02 / what you get

What happens to your data

Kept

  • The main video and one audio track of the VOB file you upload are used
  • 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
  • Interlaced footage, typical of DVD, camcorders and TV recordings, is de-interlaced so there are no comb lines on moving objects
  • Surround sound (5.1) is kept when the source has it
  • The result is usually smaller than the original, because H.264 compresses much better than older codecs

Good to know

  • DVD menus, chapters and subtitles are not converted.
  • A DVD is split into several VOB files (VTS_01_1.VOB, VTS_01_2.VOB and so on). Each file converts on its own, so join them first if you want one video.
  • Copy-protected commercial DVDs cannot be read.
  • 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.

VOB vs MP4

VOB

A VOB file is the video format found on DVDs: it holds the movie, audio tracks and menus in one stream. Ripped DVD folders are full of them, and converting to MP4 makes them playable anywhere.

Used in: DVD movies · Ripped DVD folders

MP4

An MP4 file is the most universally supported video container — plays on every device, browser, and platform. The default choice when you're not sure what format to use.
