Hey guys, weird stuff happened to some P2 Footage that I am using. It was loaded yesterday and converted to quicktimes in fcp. Unfortunately it was put on two drives and I was asked to consolidate it onto one, which I used Media Manager to do. When I opened the new project it seemed that some of the clips were messed up with digital hits or all gray. Now if I open those clips in qt player they are fine, but in the browser there seems to be files with the same same plus a "-1". All the problem files also say "av" after them. If I try to import the clips into fcp without the -1 clips, then I keep getting an error message that says that those files are missing. But when I import those files, they play messed up and then fcp freezes. Anyone know what I can do? Why do the files play fine in QT player?

I found out it has something to do with files over 2gigs or something and possibly drive formatting...anyhow I have found that if I don't try to play the clips in FCP but import them then export them as linked movies the linked files will work. Lame and time consuming, but glad I figured out a work around.

Unfortunately I was not there when this was all done, and it looks like they did not keep the mxf files, they just plugged the card reader in and converted to quicktimes and ditched what was on the cards...which I would never have done.
How do I make it a ref file from QT pro? I see the option for a "hinted movie" or a "quicktime media link", but I don't think these are the same thing as a ref file. This what I tried to do from FCP, and it looked like it was working...at least I could actually see the picture rather then just digital noise...but unfortunately I realized (after I had done them all) that they freeze when you try to play them in fcp. The only way I was able to really make it work was to export a qt movie from QT Pro, but I want to keep them DVCPROHD, and isn't that method just recompressing them and degrading them?

If you do a Save As you can create a ref video. I just tried it with a DVCPro HD clip and it plays and has the same parameters as the original.
If you Export (Movie to QT Movie), you have to write an entire new clip and I don't know if there is any loss. I tried that, too, and a quick look seemed to show no obvious problems. The only difference I could see was the four tracks of audio from the original track were made into a stereo track. The frame rate remained 23.98 fps.
You might also try to post this on the Panasonic P2 forum.

Hey John,
Thanks a bunch for the help and for doing tests; I really appreciate it. I forgot about the "save as" bit in QT Pro, but of course! I am going to give that a shot tonight. By the way, in the audio export settings I found a place to make "four discreet audio channels" and it seemed to maintain 4 separate mono audio channels when I brought it into FCP.

How are your drives formatted? Mac OS Extended?
All the best,

Jeesh, this is not my drive nor did I think to see how it was formatted, but when I do a "get info" it says "MS-DOS File System (FAT32). Which doesn't sound right to me...though I don't know much about drive formatting, sadly.
Re: Darn by Tom Wolsky on Aug 7, 2007 at 10:44:45 pm
There's a 2G file size limit with that format on a Mac. The drive needs to be reformatted as Mac OS Extended, which means copying everything off it, reformatting it and copying everything back.
