Updated over a week ago transcodes video and audio into different resolutions for playback. Just upload a high-quality file, and we'll make sure it looks great and plays back great. The original file is always stored for download.

  • Codec: H.264/H.265 (HDR-only)

  • Format: MP4

  • Profile Level: closest is High 4.0

  • Bitrate: HD is maxed 4Mbps, and SD is maxed 2.2Mbps

  • Framerate: same as the source

  • Interlaced videos: interlace videos are de-interlaced to playback on the web. The original interlaced video is available for download.

  • Color Space: Rec 709

Audio proxies

Audio specs cover both audio-only and audio-video files

  • Codec: AAC

  • Format: MP4

  • Bitrate: 128 kbps

  • Channel layout: Stereo (single channel, see below)

Multichannel support does not support multiple audio tracks. Only the first track would be extracted when downmixing to a stereo file. Therefore, we recommend flattening it into one channel before uploading to

However, when multiple audio channels are sent as a stereo/3.1/5.1/ 7.1 channel layout on the same audio track, all channels will be played back in the player.

If a file has more than 8 channels, the transcode will not be able to play it back in, but the file will still be able to be downloaded and played locally.

NOTE: Channels 1-8 & 16 are supported, 9-15 are not supported.


Q: What about formats of other asset types? How are they converted?

A: Image types are converted into JPEG and PDF and AI file types will convert to PNG.
