Add blank video track to audio

Is there a quick way to add a blank video track to an audio-only file.

I have a handful of audio-only files that I am going to be multicliping to video files, and I've figured out an easy way to do this, IF I can get a blank video track attached to the file.

Basically... change my .wav file to a .mov file with a blank video track.

I'm trying to do this in compressor because I need to do this in batch, but I can't seem to get it to work. pulled in the .wav files and applied QT ProRess 422 with audio pass through and i get this error when I submit:

Failed - 3x Can't transcode to QuickTime, source has no video or audio

Any help would be great! Thanks.

Final Cut Pro 7, Mac OS X (10.7.2)

Set up a Timeline in FCP using the codec you want.

Drop the .wav onto the Timeline. Export to QuickTime with Current Settings.

Note that you will have Sequence timecode on this clip. You might want to change the Sequence start tc to match the source tc of your .wav file.

Thanks. I actually just figured that out in the past bit. Seems to be the ONLY way to do this that I've found.

Sadly there doesn't seem to be a batch way of doing this. Have to take each clip one-by-one. If you can think of a way to batch do this (wish Compressor did it somehow) let me know. I have a lot of clips to do this with and it will take quite a bit of time with this one-at-a-time method.

Thanks for replying!

Other apps like QuickTime and Compressor just take the input file and spit out a modified version of it.

Final Cut Pro has to be able to play out to tape, for example. If you were to master in Assemble mode to tape, it needs to provide video signals too, so that signal is there by default. Although you can turn it off when exporting as a file or Insert editing.
