02 / what you get

What happens to your data

Kept

  • Videos from iTunes and Apple devices are read
  • H.264 video with AAC audio, the combination that plays on every phone, computer, TV and browser
  • The file is set up for streaming, so it starts playing before it has fully downloaded
  • The original resolution and frame rate are kept
  • A phone video recorded sideways or upside down is turned the right way up
  • Surround sound (5.1) is kept when the source has it

Good to know

  • Videos bought or rented in iTunes are copy-protected and cannot be converted. Only DRM-free M4V files work.
  • The video is re-encoded, which is slightly lossy. Only one video track and one audio track are kept; extra audio tracks and subtitles are left out.
  • A width or height that is an odd number of pixels is trimmed by one pixel, because video encoders need even sizes.
  • HDR video (for example from a recent iPhone) is converted to normal SDR colors, and 10-bit video becomes 8-bit, so it plays everywhere.
  • Files up to 150 MB are accepted. Long or very high-resolution videos can take several minutes, and a conversion that runs past about 4 minutes is stopped with a message.
