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 with 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)

NOTE: 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 a maximum of 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. For the most part, they should be okay; we 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 on Fullscreen 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 Uscreen, and if you notice that it is going too slow, take a look at our troubleshooting upload 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 will take transcoding and the more likely buffering will be experienced initially for your 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 users.

If you would like to speed up the uploading process a bit, you might want to consider using Dropbox to upload your videos by using 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 we would suggest -9 dBFS.

Tip: Make sure you are using one of our supported browsers before you begin uploading your videos to Uscreen.

To upload your videos, 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.
