# What are video ads formats and what do I see in report?
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.

**WHERE DOES VIDEO APPEAR**
 
**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)**
**Example of video campaign 2 (length: 1.16 min., VTR: 45%, CPV achieved: $0.004)**
**Example of video campaign 3 (length: 1.00 min., VTR: 6%, CPV achieved: $0.06)**
**Example of video campaign 4 (length: 15 sec., VTR: 82%, CPV achieved: $0.002)**
**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.
