# Video # VAST # VAST Video VAST (Video Ad Serving Template) is a video ad served inside a publisher's own video player. Instead of shipping a fixed-size creative, you supply one video and the player renders it in whatever slot it has available. That single point drives most of the specs below: because the player controls the frame, aspect ratio matters and pixel dimensions do not. #### Two ways to supply the creative A VAST video campaign can be set up either by uploading the video file to Eskimi, or by pointing Eskimi at a VAST tag hosted on the client's ad server.
OptionWhat you supplyWhen to use it
Upload an MP4The video file itself, uploaded to Eskimi. Eskimi generates the VAST response.The default. Use it whenever you have the raw creative and no third-party ad server is involved.
External VAST URIA remote VAST tag URL from the client's ad server (Campaign Manager, Flashtalking and similar).When the client serves and measures the creative from their own ad server, or needs to swap the creative without re-trafficking.
- The two behave differently once the campaign is live, so it is worth knowing which one you are working with: The specs below apply to MP4 uploads. With an External VAST URI the creative lives on the client's ad server, so they own the file type, ratio, size and duration — Eskimi cannot validate or change it. Send them the specs before they traffic the tag. - Skip offset is not editable on an External VAST URI. The "Skip after seconds" field only affects uploaded MP4s; with a remote tag the skip behaviour comes from the client's VAST response. - Tag-wrapped third-party measurement is not supported on an External VAST URI. See "Third-party tracking" below. #### Creative specifications
AttributeWhat to useRequired or recommended
File typeMP4Required
Aspect ratio16:9 (landscape) or 4:3Required
Resolution720p is a good default; 1080p is fine tooRecommended
File sizeUp to 5 MBRecommended
DurationFrom 5 sec. upwards — no fixed capSee "Video duration"
Fixed pixel dimensionsNot applicable — the player scales the creative to the placement-
The two things people get wrong: - There is no required pixel size. Older versions of this article listed dimensions such as 320x480 or 1024x768. Ignore them — VAST creatives adapt to the placement, so only the aspect ratio needs to be correct. - 5 MB is a recommendation, not a rule. A file above 5 MB will still run; it just loads more slowly, which can cost you impressions and completions on slower connections. Keep it under 5 MB when you can, but do not reject a creative for being larger. ##### Aspect ratio Aspect ratio is the spec that actually needs to be right. Supply the video in one of the following:
Aspect ratioTypical placementNotes
16:9Desktop and mobile in-stream, landscape playersThe most widely supported ratio — use this if you only produce one version
4:3Older / legacy playersAccepted, but reaches less inventory than 16:9
A creative in the different ratio is not rejected, but the player will letterbox or pillarbox it — black bars top and bottom, or down the sides. Anything important near the edges of the frame can end up cropped or visually cramped, so keep logos, legal text and the CTA well inside the safe area. #### Video duration There is no single maximum duration, and no length that is right for every campaign. What to use depends on the trade-off you want to make. ##### What the format supports - Under 5 sec. — serves as a non-skippable ad. - 5 sec. and above — serves as a skippable ad (see "Skip offset" below). - No fixed cap. A large share of bid requests accept up to 30 sec., and a meaningful share accept 30–60 sec. Longer creatives can run, but on progressively fewer placements. ##### The trade-off Length pushes two things in opposite directions: - Available inventory. The shorter the video, the more placements it can serve on. A publisher that only accepts up to 30 sec. will not bid on a 45 sec. creative, so scale narrows as duration grows. - Video completion rate (VCR). The longer the video, the smaller the share of users who watch it to the end. Internal comparisons have seen roughly 82% VCR on 10 sec. creatives against around 50% for a standard-length VAST video. So a long creative is a legitimate choice when the message needs the time and the campaign is measured on something other than completions. If VCR or scale is the KPI, shorter wins. Decide the length from the KPI, not from a spec sheet. #### Skip offset Skippability is a lever worth using deliberately. If a video can be skipped at 5 sec., a large share of users will skip it there — and the brand message never lands. Eskimi lets you move or remove that skip point. Set it in the "Skip after seconds" field when you upload the MP4. Note that this field has no effect on an External VAST URI — a remote tag carries its own skip offset, set by the client's ad server. - 5 — the default: the user can skip after 5 sec. - 0 — no skip option at all; the ad is non-skippable. - Up to 30 — the protocol ceiling for the skip offset itself. This is a limit on when the skip button may appear, not a limit on how long the video may be. Pushing the skip point out protects the message but reduces the number of players willing to serve the ad, and users who cannot skip are more likely to abandon the content. Treat 0 as a deliberate choice for a short creative rather than a default.

VAST does not support JavaScript tags, so the pixel is the standard route — but it only reports impressions to third-party platforms such as Integral Ad Science. To measure anything beyond impressions — viewability, brand safety, IVT — the VAST video has to be wrapped in a third-party tag. #### VAST Examples [![vast-example.png](https://manual.eskimi.com/uploads/images/gallery/2026-08/scaled-1680-/jVaH2z8GFVpzX2Ty-vast-example.png)](https://manual.eskimi.com/uploads/images/gallery/2026-08/jVaH2z8GFVpzX2Ty-vast-example.png) [![vast-example-2.png](https://manual.eskimi.com/uploads/images/gallery/2026-08/scaled-1680-/3l1FCLku4Dk9CBJN-vast-example-2.png)](https://manual.eskimi.com/uploads/images/gallery/2026-08/3l1FCLku4Dk9CBJN-vast-example-2.png) # Remote VAST URI ##### **How to upload Video Remote VAST URI:** **Step 01:** Log in to your DSP account > go to "***Creative Sets"*** > and click "***Add creative set"***.

For some exchanges this is a required value (i.e. DC), default is 5s. [![image-1705394296959.png](https://manual.eskimi.com/uploads/images/gallery/2024-01/scaled-1680-/UB1YZSsrEDSvvlxj-image-1705394296959.png)](https://manual.eskimi.com/uploads/images/gallery/2024-01/UB1YZSsrEDSvvlxj-image-1705394296959.png) **Not necessary:** Upload companion banners. Companion banner should be one from most popular sizes: 300x250px, 320x480px, or 480x320px. **Not necessary:** Add description and Call to action text. Default CTA is "Lear more" and this is changed only in placements, which support that. It will describe a call to action button for the destination URL. **Step 7:** Save your video ad. # VAST Video Wrapping, Upload & Execution ##### **Introduction** Wrapping a VAST (Video Ad Serving Template) URI into a 3rd party VPAID (Video Player Ad-Serving Interface Definition) tag offers several advantages in the digital advertising ecosystem. Firstly, by utilising a VPAID tag, advertisers gain access to enhanced interactivity and engagement features for their video ads. VPAID enables the inclusion of interactive elements like clickable overlays, interactive games, and surveys within the ad unit, providing a richer user experience. Secondly, wrapping the VAST URI in a VPAID tag allows for seamless integration with various video players and ad-serving platforms, ensuring compatibility and widespread distribution across different environments. Additionally, the VPAID tag provides a standardized API for tracking and reporting ad metrics such as viewability, ad interactions, and performance data, enabling advertisers to make data-driven optimizations and measure the effectiveness of their video ad campaigns accurately. Overall, wrapping a VAST URI into a 3rd party VPAID tag enhances ad interactivity, facilitates widespread ad distribution, and enables comprehensive ad measurement and optimization capabilities. --- ##### **Practical implications** To wrap a VAST (Video Ad Serving Template) URI into a 3rd party VPAID (Video Player Ad-Serving Interface Definition) tag, you need to follow a specific process. **Retrieve the VAST URI from the ad source**, which typically represents the XML-based ad response. To retrieve the necessary URI you need to first setup your video campaign on Eskimi DSP. The VAST URI will be found in the campaign's approval page under the Creatives section. Check the screenshot below: [![Screenshot 2023-05-19 at 16.35.14.png](https://manual.eskimi.com/uploads/images/gallery/2023-05/scaled-1680-/H2qxCbspypGlTHv5-screenshot-2023-05-19-at-16-35-14.png)](https://manual.eskimi.com/uploads/images/gallery/2023-05/H2qxCbspypGlTHv5-screenshot-2023-05-19-at-16-35-14.png) **Remember:** If you are planning to wrap the VAST URI into the MOAT, IAS or any other 3rd party tracker, you will need to provide VAST URI until **&preview=1**. Also please add in the end of the URL **&vastVersion=2** this will open more available inventory later, when delivering campaign. **Remember:** The original video campaign **can't** be deleted, expired or rejected. Leave it in pending status until the actual campaign ends. **If you need to upload a 3rd party VPAID tag,** it is necessary to select **Remote VAST URI** as your video type and paste the VAST URI as usual. Such VPAID tags will only run on VPAID compliant environment - mostly web publishers. To know more about VPAID check our comprehensive guide: [https://manual.eskimi.com/books/creatives/page/a-comprehensive-guide-to-vpaid-web-advertising](https://manual.eskimi.com/books/creatives/page/a-comprehensive-guide-to-vpaid-web-advertising) [![Screenshot 2023-05-19 at 16.53.17.png](https://manual.eskimi.com/uploads/images/gallery/2023-05/scaled-1680-/hm7F5YJQj7Gbf6KN-screenshot-2023-05-19-at-16-53-17.png)](https://manual.eskimi.com/uploads/images/gallery/2023-05/hm7F5YJQj7Gbf6KN-screenshot-2023-05-19-at-16-53-17.png) **Remember:** you can select VPAID viewability tracking method which will wrap the VPAID tag into Eskimi tag. By doing so advertisers will be able to track viewability on Eskimi DSP. It is necessary understand that such method will cause timeouts of retrieving the original video file from the tag, because of this the preview page (only) will not work, but the campaign will run as usual. [![Screenshot 2023-05-22 at 08.42.11.png](https://manual.eskimi.com/uploads/images/gallery/2023-05/scaled-1680-/jZBB7dtc9Jikqs33-screenshot-2023-05-22-at-08-42-11.png)](https://manual.eskimi.com/uploads/images/gallery/2023-05/jZBB7dtc9Jikqs33-screenshot-2023-05-22-at-08-42-11.png) **If you need to upload a 3rd party VAST tag (OMID tag)**, then you will need to upload the original VAST mp4 and add the OMID tag under *Verification wrapper URL.* *[![Screenshot 2023-05-19 at 16.57.41.png](https://manual.eskimi.com/uploads/images/gallery/2023-05/scaled-1680-/Hf1aJYr4CrC0QvBM-screenshot-2023-05-19-at-16-57-41.png)](https://manual.eskimi.com/uploads/images/gallery/2023-05/Hf1aJYr4CrC0QvBM-screenshot-2023-05-19-at-16-57-41.png)* **Remember:** You will need to change the VAST URI located in the tag to *{vast\_url\_enc}*. **Remember:** That for such setup you can enable OMID viewability tracking method. Afterwords, **set up the campaign** as usual. --- #### **Troubleshooting** Before any upload we recommend to first upload the VPAID/VAST tag into VAST video validator: [https://googleads.github.io/googleads-ima-html5/vsi/. ](https://googleads.github.io/googleads-ima-html5/vsi/)This is a universally used tool that allows to instantly see if the tag will be rendering properly, if all the metrics are being fired and receive errors. # VAST Video placement types/tracking options. All the options that we can track in bid request for VAST Videos are in the pictures below. [![image-1632303032934.png](https://manual.eskimi.com/uploads/images/gallery/2021-09/scaled-1680-/RyYR2qmdZckPcFJ7-image-1632303032934.png)](https://manual.eskimi.com/uploads/images/gallery/2021-09/RyYR2qmdZckPcFJ7-image-1632303032934.png) # IBV # IBV Video #### **What is IBV?** IBV (in-banner-video) format is basically an HTML5 video banner, that takes up regular banner placements, and also the IBV format follows regular banner sizes. In Eskimi DSP we serve IBV video in **300x250** size. However, other sizes are possible as custom HTML banners. --- #### **Features** **Automated upload:** When uploading IBV video to Eskimi DSP, our dashboard will take the file and will first convert the dimensions of the video to 300x250, then if your video for example is in 16:9 aspect ratio, we downscale the video and add letterboxing automatically, in order to scale the video properly to the 300x250 dimension. **Companion Banner (optional):** as well every dashboard user has the option to upload a companion banner. This is a regular image that can be shown when the video ads, but it is not required. The dimensions of the image should be 300x250, file formats: .PNG, .JPG, .JPEG, max file size: 150 kb. **Description (optional):** here you can add a short 90 character description of your video ad ( this description does not appear anywhere visually) **Call to action text (optional):** here you can change the Call-To-Action button text, which is displayed on the top left corner of the video ad. The maximum number of characters allowed is 10. **Controlling video start:** If “Play when in viewport” checkbox will be selected - video will start only when banner is in-view at least **50%** (our viewability standard is - 50% for 1s, so it’s pretty the same). [![image-1613142208205.png](https://manual.eskimi.com/uploads/images/gallery/2021-02/scaled-1680-/image-1613142208205.png)](https://manual.eskimi.com/uploads/images/gallery/2021-02/image-1613142208205.png) [![image-1613142351039.png](https://manual.eskimi.com/uploads/images/gallery/2021-02/scaled-1680-/image-1613142351039.png) BE AWARE, that this feature might impact video metrics performance, as video only will start after it’s vieawble, so video metrics might decrease (views).](https://manual.eskimi.com/uploads/images/gallery/2021-02/image-1613142351039.png) --- #### **Limitations** **Duration:** the maximum duration of the IBV video is **up to 30 seconds**. This is the maximum time, which is recommended by all exchanges. However, if you will upload a video that is longer than 30 seconds, the user will be prompted to interact with the ad in order to continue watching the video. --- #### **Requirements summary** \- File Type: .mp4 \- Recommended length of the video is a maximum of 30 seconds. If more than 30 seconds the user will be prompted to interact with the video in order to continue watching. \- Maximum Video file size: up to 5MB. # VPAID & OMID # A Comprehensive Guide to VPAID - web publishers #### **Introduction** In the dynamic world of online advertising, there are various technologies and standards designed to enhance the delivery and measurement of video ads. One important standard in this realm is VPAID (Video Player Ad-Serving Interface Definition). This manual article aims to provide a comprehensive understanding of VPAID, exploring its purpose, applications and the challenges it face in the market. --- #### **Understanding VPAID** VPAID, or Video Player Ad-Serving Interface Definition, is a standard that enables seamless communication between video players and ad units, **enhancing the interactivity and measurement capabilities of video ads**. Alongside facilitating interactive experiences like clickable overlays and interactive games, VPAID also plays a crucial role in **video viewability tracking**. With VPAID, advertisers and web publishers can track the **visibility** and **engagement** of their video ads by integrating JavaScript code within the ad unit. This code captures visibility-related events and communicates them to the video player, allowing for the measurement of viewability metrics such as full view, partial view, and non-view. By leveraging VPAID's standardised API for video viewability tracking, advertisers gain insights into **viewable impressions** and **viewability rates**, enabling them to optimise their campaigns for maximum ad visibility and effectiveness. Even though VPAID can be used across various platforms and devices to track viewability metrics for video ads. The biggest adoption is seen only between **web publishers.** Therefore, **if advertisers will use VPAID adapter or tags they will mostly serve ads on web publishers.** --- #### **How it is used** VPAID is widely used by video web publishers and advertisers to enable interactive features, track user **engagement**, and **measure video viewability**. By integrating VPAID-compliant ad units, advertisers **can incorporate video viewability tracking capabilities into their campaigns**. This allows advertisers to and optimise their campaigns for enhanced ad visibility and effectiveness. Furthermore, web publishers can leverage VPAID to offer transparent viewability metrics as a value-added service, promoting trust and accountability in their advertising inventory. --- #### **How VPAID is used at Eskimi?** Eskimi, a leading advertising platform, leverages the Google VPAID adapter to enhance their video ad capabilities, particularly when it comes to **measuring viewability**. By utilizing the Google VPAID adapter, **Eskimi seamlessly integrates their video ad-serving technology with the widely used Google IMA SDK** (Interactive Media Ads Software Development Kit) which is used by web publishers. This integration allows Eskimi to ensure that video ads served through their platform are not only interactive but also accurately track viewability metrics. **The Google VPAID adapter provides Eskimi with the tools needed to deliver engaging video ads while effectively measuring viewability**, giving advertisers and web publishers the insights they need to optimise their campaigns for better visibility and overall performance. By utilising the power of the Google VPAID adapter, Eskimi enables advertisers to achieve greater transparency and accountability in their video ad campaigns, ultimately driving more effective and impactful advertising experiences. --- ##### **Practical implementations** To enable video viewability tracking advertisers should select VPAID when uploading original VAST video or remote VAST/VPAID URI ads. See the example below: [![Screenshot 2023-05-19 at 15.20.28.png](https://manual.eskimi.com/uploads/images/gallery/2023-05/scaled-1680-/hrG8E2PC3miDfOdu-screenshot-2023-05-19-at-15-20-28.png)](https://manual.eskimi.com/uploads/images/gallery/2023-05/hrG8E2PC3miDfOdu-screenshot-2023-05-19-at-15-20-28.png) Keep in mind that by selecting this tracking method you will only search for ad placements which supports VPAID. Therefore, the traffic may be limited to web publishers which support VPAID. Also, VPAID and OMID can be selected simultaneously if a VAST video mp4 is uploaded. # A Comprehensive Guide to OMID - app publishers #### **Introduction** In the dynamic world of online advertising, there are various technologies and standards designed to enhance the delivery and measurement of video ads. One important standard in this realm is OMID (Open Measurement Interface Definition). This manual article aims to provide a comprehensive understanding of OMID, exploring its purpose, applications, key differences, and the challenges it faces in the market. --- #### **Exploring OMID** OMID, or Open Measurement Interface Definition, is a standard developed by the IAB (Interactive Advertising Bureau) to facilitate third-party verification and measurement of ad impressions. It allows independent verification providers to measure various metrics, such as **viewability**, **ad verification**, and **audience measurement**, in a consistent and standardised manner. OMID provides an API that enables measurement and verification scripts to interact with the ad container, ensuring transparency and accountability in the advertising ecosystem. --- #### **How it is used** OMID plays a crucial role in **enabling viewability measurement for app publishers**. By integrating the OMID SDK into their mobile applications, app publishers gain access to standardised viewability measurement capabilities across different platforms and devices. With OMID, app publishers can work with third-party verification providers (MOAT, IAS, DV etc.) to measure viewability metrics such as the percentage of fully viewable impressions and average viewable time. The OMID SDK allows for consistent and transparent measurement, ensuring accurate and reliable viewability data. By leveraging OMID, app publishers can assess the visibility and impact of their video ads, optimise their placements for maximum viewability, and provide advertisers with the necessary insights to enhance the effectiveness of their campaigns. OMID's standardised approach to viewability measurement in the app environment contributes to increased trust and accountability, benefiting both app publishers and advertisers in achieving more impactful and successful mobile ad experiences. --- #### **How it is used at Eskimi?** Eskimi utilises OMID for viewability measurement to enhance transparency and optimise the performance of their ad campaigns. By integrating OMID into their platform, Eskimi gains access to **standardised viewability metrics from mobile apps**. When bidding on ad impressions, Eskimi leverages OMID-compliant measurement scripts to verify viewability. These scripts communicate with the ad container through the OMID API, collecting standardised viewability data. Eskimi then uses this data to evaluate the viewability performance of the impressions they purchase, optimising their bidding strategies and ensuring that their ads are seen by the intended audience. By leveraging OMID viewability measurement, Eskimi enhances transparency, providing advertisers with accurate reporting and actionable insights to optimise their campaigns for improved viewability and effectiveness. --- #### **Practical implementations** To enable video viewability tracking advertisers should select OMID when uploading original VAST video or remote VAST URI ads. See the example below: [![Screenshot 2023-05-19 at 15.37.21.png](https://manual.eskimi.com/uploads/images/gallery/2023-05/scaled-1680-/QpWDI3uXpT53Yi7O-screenshot-2023-05-19-at-15-37-21.png)](https://manual.eskimi.com/uploads/images/gallery/2023-05/QpWDI3uXpT53Yi7O-screenshot-2023-05-19-at-15-37-21.png) Keep in mind that by selecting this tracking method you will only search for ad placements which supports OMID. Therefore, the traffic may be limited to app publishers which support OMID. Also, VPAID and OMID can be selected simultaneously if a VAST video mp4 is uploaded. --- #### **Market Challenges** The adoption of OMID faces challenges due to varying implementation timelines and compatibility across platforms. Additionally, the integration and implementation of OMID-compliant measurement solutions require technical expertise and coordination between advertisers, publishers, and measurement vendors. # Video + nCard # Rewarded video with nCard #### **Introduction** This feature allows us to show video ad and display ad together for the same "impression". Our special rewarded video traffic segment allows us to serve video+end card through companion ad attribute. While uploading video MP4 file, using VAST URI, together we will add companion ad - either static or html/js creative tag. End card gets 5s as default to view so it’s also always viewable element. If user interacts with HTML/JS tag, creative stays open till user decides to close it. In campaign reporting companion ad will have "Companion impression" and "Companion clicks" metrics under “Event metrics” part. Companion clicks also reflects on main reporting data. --- #### **Practical implementation** To create video VAST campaign with end card, you just need to follow standard video VAST + companion ad upload process we [have here >>](https://manual.eskimi.com/books/creatives/page/how-to-upload-video-ads/) just don't forget to add companion banner. Companion banner should be one from most popular sizes: 300x250px, 320x480px, or 480x320px. **Remember:** as all inventory will be delivered in-app environment, we need to select only OMID viewability targeting. [![image-1705420031378.png](https://manual.eskimi.com/uploads/images/gallery/2024-01/scaled-1680-/POsWXsQT6D0owd5z-image-1705420031378.png)](https://manual.eskimi.com/uploads/images/gallery/2024-01/POsWXsQT6D0owd5z-image-1705420031378.png) "Skip after seconds" default value can be changed but not recommended to change to 0. Value should be from 5-30s. By adding longer skip value, we are filtering supported bid requests and most common is 5s. 3rd party verification tools can be used only with static and simple HTML/JS creatives (without MRAID library support in html). --- #### **Preview** After creating VAST video creative with companion we will get separate assets preview in creative edit form. We can re-upload video for same creative. We can re-upload static companion image, we can edit HTML or just re-upload a new version of HTML zip. Real creative preview will be showed in campaign preview page, where companion ad will be delivered after video.

Our special [rewarded](https://manual.eskimi.com/books/rewarded-video-campaign/page/rewarded-video) video traffic segment allows us to serve video+end card through companion ad attribute. While uploading video MP4 file, using VAST URI, together we will add companion ad - either static or html/js creative tag. End card gets 5s as default to view so it’s also always viewable element. If user interacts with HTML/JS tag, creative stays open till user decides to close it. In campaign reporting companion ad will have "Companion impression" and "Companion clicks" metrics under “Event metrics” part. Companion clicks also reflects on main reporting data. --- #### **Practical implementation** To create video VAST campaign with end card, you just need to follow standard video VAST + companion ad upload process we [have here >>](https://manual.eskimi.com/books/creatives/page/how-to-upload-video-ads/) just don't forget to add companion banner. Companion banner should be one from most popular sizes: 300x250px, 320x480px, or 480x320px. **Remember:** as all inventory will be delivered in-app environment, we need to select only OMID viewability targeting.

Value should be from 5-30s. By adding longer skip value, we are filtering supported bid requests and most common is 5s. 3rd party verification tools can be used only with static and simple HTML/JS creatives (without MRAID library support in html). --- #### **Preview** After creating VAST video creative with companion we will get separate assets preview in creative edit form. We can re-upload video for same creative. We can re-upload static companion image, we can edit HTML or just re-upload a new version of HTML zip.

Video ad formats are the different ways video ads can be presented to users across various digital platforms. Here’s an overview of the Eskimi DSPs video ad formats: 1\. **[VAST Video](https://manual.eskimi.com/books/video/page/vast-video):** Video VAST adjusts videos based on player options and content to match the look and feel of the apps and sites. 2**. [IBV](https://manual.eskimi.com/books/video/page/ibv-video):** IBV video ads are served within an embedded video player inside a 300x250 banner placement. 3\. **[Video Remote VAST URI](https://manual.eskimi.com/books/video/page/remote-vast-uri):** A video remote VAST URI allows integration with different ad platforms through third-party tags for widespread video distribution. 4\. **Video VAST + IBV:** Video VAST and IBV video creatives created at once. **SIZE** To run video ads, we suggest to use these dimensions: 300x250, 320x480, 300X600. **DURATION** It's suggested to run video ads up to 30sec but video length is unlimited **FILE TYPE** MP4 **FILE REQUIREMENTS** Video size can be up to 5MB, companion banner - up to 50 kb **ADDITIONAL FILES (not necessary )** If you’re launching a video campaign, you might add a Companion banner. One from most popular sizes 300x250px, 320x480px, 480x320px. **WHERE DOES VIDEO APPEAR** ![Punch.ng.png](https://dsphelp.eskimi.com/hc/article_attachments/115006169189/Punch.ng.png) ![Saharareporters.png](https://dsphelp.eskimi.com/hc/article_attachments/115006126245/Saharareporters.png) **VIDEO REPORT** In the report you see impressions, clicks, CTR, reach, spend, and other general information. Additionally, you see how many users started watching the video, how many of them watched the first quartile (of the total video length), how many watched till midpoint, third quartile, and, finally, how many users completed the whole video. Also, you can see how many users watched the video muted/not muted and how many of them paused/resumed the video. You would also see split by browsers, OS, operators, age and gender, campaign performance by site/APP, by creatives, and others. **Example of video campaign (length: 0.30 min., VTR: 23%, CPV achieved: $0.018)** ![Screen_Shot_2017-06-30_at_14.32.55.png](https://dsphelp.eskimi.com/hc/article_attachments/115006139085/Screen_Shot_2017-06-30_at_14.32.55.png) **Example of video campaign 2 (length: 1.16 min., VTR: 45%, CPV achieved: $0.004)** ![Screen_Shot_2017-06-30_at_12.29.28.png](https://dsphelp.eskimi.com/hc/article_attachments/115006124905/Screen_Shot_2017-06-30_at_12.29.28.png) **Example of video campaign 3 (length: 1.00 min., VTR: 6%, CPV achieved: $0.06)** ![Screen_Shot_2017-06-30_at_12.33.52.png](https://dsphelp.eskimi.com/hc/article_attachments/115006168389/Screen_Shot_2017-06-30_at_12.33.52.png) **Example of video campaign 4 (length: 15 sec., VTR: 82%, CPV achieved: $0.002)** ![Screen_Shot_2017-06-30_at_12.22.26.png](https://dsphelp.eskimi.com/hc/article_attachments/115006138145/Screen_Shot_2017-06-30_at_12.22.26.png) **VIDEO RECOMMENDATIONS** As seen in the examples above, video campaign results may vary and CPV reached can start from $0.002 and go up to $0.06. We recommend to use videos not longer than 30 seconds, more important we recommend to pay more attention to the content of the video from the user perspective: don't try to put all the information in one video, rather try to make it more engaging, light, and in a popular format.
