  M4v or mp4

  Posted by Scott Sniffen on July 8, 2010 at 3:13 pm

  I am trying to export a clip for Viddler. They spec h.264 with a file extension of m4v or mp4. Not getting good results in QT Conversion. If I choose h.264, there is no option to use an m4v or mp4 extension. If I uses MPEG-4, the results are nasty in HD. Any ideas on the best way to get a good HD file for Viddler?

  Thanks,
  Scott Sniffen

  Do not use QuickTime Conversion. Use Compressor to encode.

  Export QT Movie and drop that file into Compressor.

  Extension is just an extension name. You can change it to m4v, mp4, mov, flv, etc.

  Good question!! I have been obsessing over this for a few weeks now. I may be completely wrong here, but I have been told that all you have to do is change the file extension from mov to mp4. (And the same with a FLV file?)

  MP4 (with extension .m4a) is a Lossless codec. They have a pre-set for this in Compressor.

  H.264/MPEG-4 Part 10 is a Lossy codec and this is what I think my clients are asking for when they say mp4. They have many presets for this in Compressor.

  Vimeo also wants a H.264 codecs with the file format as mp4. Is this also just a matter of changing the extension?
