DVCPRO HD export issues
My problem: exporting a self-contained QuickTime from a DVCPRO HD 23.98 timeline. What happpens is I get back a master file with .av files associated with it, and the master file is not the right frame size. It is bigger. I have split screen layers in the original time line which must be the issue, so when itry to control the export via QuickTime conversion, I get the right frame size, but the sync is way off. The frames do not match my original timeline. My system: Intel Mac Pro 2.66 with 6 gigs ram, FCP 6.0.1.
Thanks,
Matt

Do you have enough hard drive space on the drive you are exporting to?

Regarding the av file extension:
I’ve only seen the export turn the QT file into a file with the .exe extension. OSX see’s it as a Unix file. You can rename it it with .mov and it should be fine or re-export as below.Regarding the export Frame size:
This is a known DVCPRO HD bug in FCP 6.01. Make sure you export your file by checking “recompress frames”. This will then take about 3X realtime for your file to export, but the frame size will be correct.

[Andy Edwards] “Regarding the export Frame size:”
My analysis is far from complete, but I think this only happens when there’s no filter of any type on a clip and you export. You can put a dummy filter on a clip (like a desaturation filter with a value of 0) and then export. That way, you won’t have to recompress, which is losing a generation if you check that box and takes forever and a day as you have found out.

Thanks, I had guessed this was a bug– just one I had not heard of. Thanks about the recompression trick.

Is it possible that the hard drive you’re exporting to is PC formatted? On a FAT-32 PC drive, files larger than 4 GB aren’t allowed. I’ve never tried to export a big HD file to one, but it’s possible that FCP and/or Quicktime is automatically creating the AV files to get around this size limit.
I’ve got another possible workaround for the 1280 v 960 bug (which hit me for the first time yesterday and boy was I mad). Export your movie as you normally would (without checking the recompress frames box). Bring that movie back into Final Cut, open it in the viewer, and hit export Quicktime movie again. This second Quicktime movie that you exported will be the proper size. It takes a while to export, but I suspect it’s faster than recompressing all frames, although I’ve not done a time test. I also don’t notice any quality difference between the original movie and the replacement, which is not to say it isn’t there, but I haven’t been able to see one.
