Video File Requirements

When submitting video files, ensure they meet these requirements.

  • Primer on formats: Audio and video codecs determine the language in which the sound and picture data is stored. The file extension describes the kind of container around the data. Codecs and file extensions are mostly independent, with the notable exception of Windows Media which is both a codec and a file format (WMV).
  • Accepted file extensions: .MPG .MPEG .QT .MOV .WMV (do not change your file extension of your files unless you actually convert the file)
  • Accepted video codecs: MPEG2, MPEG4, Sorensen, Windows Media, Cinepak, MJPEG.
  • Accepted audio codecs: MPEG1, MP3, AC-3, AAC, AIFF, WAV, Windows Media.
  • File size: Video files must be less than 50MB.
  • Bitrate: At least 3 Mbps for video and 192 Kbps for audio.
  • Dimensions: For best results, submitted videos should be at least 400 x 300 pixel resolution.
  • Recommended format: Every video is different, but we have found that Windows Media files with 4 Mbps variable bitrate encoding have great quality and compression. Another good alternative is the MPEG4 codec inside a .MOV file, .MPG file, or .MPEG file. Format conversion: Atlas can assist you in converting your high-resolution video files into one of these formats that can be uploaded into Atlas. You can transfer your video files to us using our FTP site or send us a data DVD. Contact your support manager for more information.
