Smart rendering iMovie DV clips to avi

Is it possible to use Vegas to convert DV files imported from the stored media in an iMovie project on a Mac to avi files, without recompression?

A somewhat related question: with old 4x3 D8 clips stored as .avi files, Vegas correctly sets the pixel aspect ratio to 0.9091. With DV files imported from the Mac, Vegas sets the pixel aspect ratio to 1.0000. Of course this can be adjusted in Vegas, but is there any way of always reading such files with the NTSC pixel aspect ratio?

There seems to be three potential problems--first, just reading the Mac-created files on a windows machine, second, opening the files in Vegas and third, whether they will smart-render or recompress. I'd suggest that you simply "try it" or upload a sample clip to Dropbox or something for testing by forum contributors.

I agree with wwaag.

FFMPEG would be able to transform dv.mov (quicktime) to either .DV stream or DV-stream.avi (DV inside and AVI container) Even better would be to get the DV stream to DV.mxf, then Vegas would not recompress untouched footage.

Are you sure that these are DV files? It sounds like you are reaching into the internal files controlled by the iMovie project and ripping them out. Depending on how they were imported, they may not be DV anymore even though the source was DV. These may actually be stored in the Apple Intermediate Codec (AIC) format that iMovie uses.

I would make sure that you absolutely know what codec these files use before you do anything. You can use the Movie Inspector (Ctrl+I) in QuickTime to determine what codec they use.

BTW, Vegas Pro can edit DV QuickTime files so there is actually no reason to convert them to AVI except for improved performance.
