Encoding Guidelines and Recommendations

MediaCore accepts most major video and audio codecs available today and will seamlessly convert those files to enable playback on mobile and desktop platforms, but to get the best looking result and minimize the risk of conversion and playback issues, we recommend you follow these guidelines for audio and video files uploaded to MediaCore.

Container Formats

Audio should be packaged as .m4a or .mp3, video should be packaged as .mp4.

Audio Encoding Settings

  • Audio-only files should be encoded in MP3 or AAC-LC format.
  • Audio streams inside video files should be encoded in AAC-LC format.
  • All audio should be 44.1kHz (though if the source material has a different sample rate, use the original) in stereo (2 channels).

Video Encoding Settings

Video streams should be encoded with:

  • H.264 + high profile + CABAC
  • 16:9 aspect ratio
  • 4:2:0 Colour Space
  • Progressive scan (no interlacing)
  • Square pixels
  • Constant frame rate
  • Frame rate should match the source material

Recommended video dimensions and bitrates:

854x480 at 2,500-5,000 kbps
1280x720 at 5,000-10,000 kbps
1920x1080 at 10,000-20,000 kbps
