Quicktime file with DV video

I used the Life Flix Macintosh app to save DV video from my DV camcorder to my Macbook. This app uses the Quicktime file (.mov) file container. The video codec, however, is DV video.

I copied these files to my Dell laptop and tried to import them into Sony Movie Studio (Platinum, version13.0, build 879, 64-bit). The version of Quicktime on this laptop is 7.7.8 (1680.95.71).

This import fails. The message is "Warning: An error occurred while opening one or more files. The number of channels is not supported."

I thought maybe the Quicktime file format was the problem. So I used ffmpeg to convert to an avi file format (same DV codec, same audio codec). Movie Studio also fails when trying to import the avi file. The message is "Warning: An error occurred while opening one or more files. An error occurred while opening a codec."

Anyone have any ideas? Problem with the particular variant of the DV codec?

Some more stuff I discovered:

Quicktime can play these Quicktime files just fine. So can the VLC player.

VLC shows this codec information in the Quicktime file:

Stream 0:
Type Video
Codec DV Video (dvc)
Resolution 720x480
Frame Rate 29.970030

Stream 1:
Type Audio
Codec PCM S16 LE (s16l)
Channels 2F2R
Sample Rate 32000 Hz
Bits per sample 16

The audio has 4 channels. Normally DV is stereo so that is probably the issue. If you have QT pro you can delete the two rear channels.

The camera was apparently set for 4 channel at 32000hz rather than 2 channel at 48k.

Quicktime Pro will also convert your QT DV to something more usable.

You are correct.

I used ffmpeg to copy the video stream and to convert the audio stream to stereo (2 channels). Still has the Quicktime file container. The import action works now.

Thanks for the reply.
