When working with someone who is preparing QuickTime movies for use with Pro Tools, ensure that you communicate the following:
QuickTime DV movies can be either complete (consolidated) Quicktime files (where media is copied into a Quicktime file) or Quicktime reference files (where just a small composition is in the Quicktime file which references the original DV files).
When exporting from Avid, always use the Apple DV codec. Do not enable “Use Avid Codec” in the export dialog. If an Avid-codec DV movie is imported into Pro Tools, you cannot play it unless you have installed an Avid video peripheral.
Pro Tools does not support audio from a DV Stream file. DV Stream files contain the entire data stream that has been transferred or recorded over the FireWire cable from a camera. In this type of file, the audio and video data are stored in an interleaved fashion, as opposed to a QuickTime file where audio and video are stored separately.
