Video compression reduces a video's file size to improve upload and playback speed without negatively impacting video resolution, at least that's the goal. For the best upload and playback experience in Uscreen, we recommend following these video encoding and compression guidelines prior to uploading:
- Format: MP4 (file extension .mp4)
- 1080p/2K or smaller - Videos less than 2048x1152p are considered standard (this is also the recommendation for horizontal ratio)
- H.264 video codec - the most common codec and supported by almost every device
- 20 fps - 60 fps (23.98 fps is a good option)
Uscreen does support 60 fps, however, some Roku and Chromecast devices do not. If your end-users are experiencing stuttering issues on these devices and your content is rendered at 60 fps, the solution is that you re-encode the files at maximum 30 fps and replace them.
Additional items you may want to check:
- 8Mbps or less - bit rates higher than 8Mbps can cause playback issues for viewers
- 10-second max keyframe interval
- 8-bit 4:2:0 or less
- Closed GOP (group of pictures)
It is important to note that large, uncompressed files or files in the wrong format, like FLV or M4V, will take longer to encode because we essentially need to encode these files in another format to serve on older devices. However, for the most part, they should be okay we just might recommend using the above formats if you run into issues like a stalled encode.
Note: If you have TV Apps, all videos must be filmed Horizontally, or in Landscape Mode, to ensure it fits the TV Screen. This is required by Apple, Google, Amazon, and Roku.
Before we transcode your files, you'll need to upload them to us and if you notice that it is going too slow for your liking have a look at our troubleshooting slow upload times guide.
We do not recommend uploading files larger than 13GB at a time. You can certainly try to upload larger files, however, the larger the file, the longer the transcoding time, and the more likely buffering will be experienced initially for your end-users due to a larger manifest for the file. We recommend you break up larger video files and add them to a collection to avoid delays in upload, transcoding, and viewing inconveniences for your end-users.
If you would like to speed up the uploading process a bit, you might want to consider using Dropbox to upload your videos, then use our Dropbox upload option. Again, we do recommend limiting uploads to 13GB at a time.
We accept most audio formats, but some things outside of AAC/MP3 will be transcoded, which may delay the readiness of the asset. Otherwise, we take non-stereo input and convert it to stereo; for higher fidelity audio, create the content with prepared stereo audio before uploading. At this time we don't have any direct standards for loudness, but would suggest -9 dBFS.
Tip: Make sure you are using one of our supported browsers before you begin uploading your videos to Uscreen.

Navigate to Content > Videos and simply drag and drop your files into the upload area.
To make your videos available in your catalog you'll need to give them a category.
