|Max file upload size:||100 MB|
|Video dimensions:||Minimum height of 144 px, up to 2048×1080 px maximum.
Note: We recommend uploading videos that are 1920×1080 for 16:9 content and 1440×1080 for 4:3 content.
Avoid uploading UHD (4K) video or higher resolution. See Transcoding Videos Using Handbrake if your videos are larger.

- Ensure that your video files include audio. If your video does not have any audio, you will not be able to upload it.
- Upload the highest quality version of your video file. For ads hosted with AlcanceMG, the system automatically transcodes the video into all necessary formats. See Transcoding Videos Using Handbrake if your original file is too large to upload to the DSP.
- Upload only a single size for each video. The DSP automatically creates copies for each size used by your ads.
Third-party VAST 2.0 or 3.0 is also accepted. Only InLine Linear ads are accepted; Non-linear and wrappers are not accepted. VAST from a third party server must contain at least one MP4 media file, but it is strongly advised that the following be in the VAST:
- MP4 high bitrate
- MP4 low bitrate
- FLV high bitrate
- FLV low bitrate
- (Optionally, but preferably) WebM high bitrate
- (Optionally, but preferably) WebM low bitrate
“Low bitrate” is around 400-600 kbps, “High bitrate” is around 1000-1200 kbps.
Multiple bitrates are recommended for broadest acceptance, with at least one version with a bitrate less than 400 kbps for mobile compatibility.
Ideally, the low bitrate versions are encoded at a lower resolution (i.e. 640×360 for 16:9 video, 640×480 for 4:3 video) if the high bitrate version is at a higher resolution. This is because the quality of a high-resolution video at low bitrate will be poor, and some devices, especially mobile, may have difficulty playing very high resolution (i.e. 1080p) video.
For more information, see Chapter 2 of the IAB Digital Video Format Guidelines.
