file length shortened after export
I’m working on a project in ProRes422HQ. When I export and convert the final project to H264 (using export as Quicktime Movie with custom setting set to H.264 compression) the final export when played back in Quicktime ends just prior to where it should. About 30secs too soon in my case. I’ve tried several things to try and resolve the problem but the same thing happens on each attempt. Finally I just used LAN rez in exports using quicktime conversion to get the thing up for preview. It’s not a frame rate issue is it? any ideas? BTW just downloaded 10.6.4 OS.
thanks.

How do we know, you have not given us the frame rate of your seq or the H264.30 secs short out of a 1 hour movie, a 60 sec movie? For major codec changes I would either export the movie with current settings and then use compressor to make the H264, or you Export with QT Conversion.

sorry. 30secs short of 2.5min. I never changed the frame rate so that probably isn’t an issue. I exported the timeline in current format as a Quicktime Movie and imported the export into a new timeline to be converted to H264. I will use compressor to see if that helps. I wasn’t sure if this was a software issue or just something inherent in prores down-conversions… if anyone had seen that before.

Sorry, I’m confused on with what you are trying to do, you export a movie to bring it back into FCP to export a movie?
Why not give specific settings of each step.
The normal method of conversion it to export as self contained with current settings, then take that into Compressor and export to the needed codec.

well I tried to just export from the timeline to H264 from prores422HQ. But the file ended up being appended. So I exported with current settings and tried converting the exported file from with in final cut pro ..seemed to be as easy as using compressor stepwise. But yeah. I could have done it with compressor. I’ll have to try that to see if the error keeps happening. My question was really asking why would the file be abbreviated on export from FCP. It was a 2:30 length file that for some reason on export was abbreviated to 2:10 . I repeated it several times to test. rebooted, etc…
