Tips & Warnings

  • The MP4 or H.264 codec options help ensure compatibility on Mac-based computers. AAC is an audio codec with similar compression standards as an MP3.
  • A bitrate is the amount of information played per second. Higher bitrates result in higher-quality video, but certain programs or devices may be unable to play video with too high a bitrate.
  • Allow up to several hours for any feature-length content to convert.
