Change DV stream from .mov to .dv container without reencoding

[DavidCasillas]

I have been using iMovieHD to edit dv files. I frecuently export to a dv file. Now I'm using sometimes FinalCut or QuickTimePro, but when I export to a dv file the video is encapsulated in a mov file. It is a bit anoying becouse it is harder for me to view in the explorer which files are original dv files and which are the encoded versions since I now have dv and mov files (depending on which app I use to edit then) which both have dv material and then mov files with the encoded version in H264.
Is there an easy way to change the container from mov to dv without reencoding the video stream again?

If it is just for Finder browsing purposes, wouldn't it be easier to use the filename for specifying what is in the container?
My_movie_20110619_dv.mov
My_movie_20110619_h264.mov

For changing containers, QuickTime Pro's Export > Movie to DV stream (.dv) shouldn't re-encode if the source file is DV .mov.

I looked for a method of doing this for a long time. Eventually, I discovered that importing a .mov file containing DV into iMovie 6.0.4 will create a .dv file in its hidden Media folder.

After importing, I close the application, right click on the iMovie project icon, select Show Package Contents, and copy or move the resulting .dv file from the Media folder. Then I delete the iMovie project.

I think this process does not re-encode. I am not 100% sure, and wish someone would tell me how to prove (to myself, for one thing) whether I am correct.

If you try this with a later version of iMovie, please let me know whether it works by posting here. I haven't gotten around to trying it with a later version.

On the other hand, exporting to DV Stream from Final Cut Express does re-encode, even though it does not need to. I learned this the hard way, after unknowingly re-encoding by using this feature many times.

Unfortunately, this does re-encode, even though it shouldn't. I learned about this on the Apple Discussion Forum. I was in denial about it for a while, and eventually accepted they are correct.
