Recommended Quality Settings
Video compressing 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 is the most recommended format to provide the best user experience)
Even though Uscreen supports various video formats, not all browsers, programs, and devices can play a particular video format, so MP4 is the safest bet when it comes to video format.
Resolution: 1080p/2K or smaller - videos less than 2048x1152p are considered standard (this is also the recommendation for the horizontal ratio)
Codec: H.264 video codec (this is the most common codec and supported by almost every device)
Frames Per Second: 20 fps - 60 fps (23.98 fps is a good option)
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 (The higher the bit rate, the less compression, which results in overall higher quality. However, be aware that the higher the bit rate, the larger the file size.)
Closed GOP (group of pictures)
NOTE: We recommend ensuring that your content doesn't have color transfer functions like "smpte2084" (also known as Perceptual Quantizer or PQ) used in HDR video.
Although Uscreen does support 60 fps, some Roku and Chromecast devices do not. If your users are experiencing stuttering issues on these devices and your content is rendered at 60 fps, the solution is that you change it from 60 to a maximum of 30 fps and replace the video.
It is important to note that large, uncompressed files or files in a different format, like FLV or M4V, will take longer to encode because we essentially need to encode these files in another format to work on older devices. For the most part, they should be okay, but we strongly recommend using the above guidelines when uploading videos to avoid any issues. Read our guide to understand more about different video formats and why we recommend MP4.
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.
Transcoding Your Video
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.

Upload a Video
To upload your videos, navigate to the Content tab, and on Videos, 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.
