Can't open FCP m2v in V8 -- what's wrong?

I can' t open an .m2v created in FCP (sent to me by someone else) by dragging to the Vegas timeline. - I get the error message "none of the files dropped on Vegas Pro could be opened." The file plays fine in WMP and and DVDA will author it without re-encoding, so it looks like its compliant.
Surely this should open in Vegas?

Well, you can't open an m2v file created from Liquid or Studio either. I requested this feature a while back but who knows if it will ever be implemented.

The file will need to be encoded as one of the many compatible formats Vegas can read.

Sorry to be the bearer of bad news.

Yes, have this problem all the time- I usually end up (with smaller files) having the file rendered to an image sequence or uncompressed QT - works in Vegas then.

FCP won't read Vegas m2v either.

A possible workaround is to create a DVD in DVDA using the file (to the DVD folders stage on hard disc), then use the 'Import DVD camcorder disc' function in Vegas to import from the DVD folders.

The problem is that Vegas won't open MPEG 'elementary stream' files, only program and transport stream files.

Rather than having to re-render on the FCP machine, you may be able to convert in QuickTime Pro ($30 and well worth it for all the things it can do).

Bummer - especially since all I wanted to do was to add fades at the beginning and end of the clip, and use V8's smart render on it.

I have the m2v and PCM audio streams from FCP. I suppose that if I author a DVDA disc with PCM audio, I can then import the vobs with muxed PCM into Vegas, do my thing and smart-render out video and AC3 audio without danger of audio sync slipping, right?

Yes, that should work.

If the source files are short enough to fit in a single .vob file, just putting that on the timeline should be OK, otherwise use the 'Import DVD camcorder disc' to create a single file from the multiple vob's.

Curious thing....

I'm working on a joint school concert video with the FCP guy. He edited the first half of the concert and I edited the second half. We used the hall audio recorded by the school's sound guy.

When I got my collaborator's m2v and PCM files, I noticed that he had overcompressed the audio and then normalized it way high, so I decided I'd replace his audio with the hall audio and tweak it the way I had done with my half of the concdert.

So I took his elementary streams, authored a DVD in DVDA (no recompression or anything), imported the vob, put the hall audio on the timeline between the audio from the VOB and matched up the beginning of the audio. To my suprise, the audio was about a half second to a second off at the end, so I had to control-drag the hall audio to match up. This is for a 40 minute take.

I'm assuming that when he rendered stuff out in FCP the length changed, but is that normal?
