# Video specifications

> Review the requirements for video creatives with Unity User Acquisition.

Video ads use in-game video through an embedded webview to market an app. While an ad only requires one video, uploading a video for each type of screen orientation (landscape and portrait) yields better optimization. When a creative contains both, Unity's valuation algorithm selects the best orientation to display. Note that with Unity, all video ads must also include an end card.

> The Apple App Store has unique rules for creatives. To adhere to Apple requirements, only depict the Apple App Store logo in creatives for iOS apps. Refer to [Apple's marketing guidelines](https://developer.apple.com/app-store/marketing/guidelines/#badges) for more information.

## Video creative specifications

Video creatives must adhere to the following specifications:

* 60 s or less
* H.264-encoded MP4 format
* 16:9 pixel ratio for landscape videos, or 9:16 pixel ratio for portrait videos
* Recommended file size is 10 MB. Maximum file size is 100 MB. Videos are re-encoded to work with various bitrates. The final video shown will be optimized for the user's available network speed and cache settings.

> **Note:**
>
> The current version of long video ads (30 to 60 s) is a beta release. The features and documentation might change between now and the next release.
