exported sequence from fcp different to timeline – audio sync and video clip problems
Hi,
I am using FCP 6.0.6
I have a sequence that I am trying to export to quicktime. I have tried with and without compression and through Compressor. Every time, the exported sequence comes out differently to the timeline original (although always in the same way).
The sound is out of sync, and even more confusingly the video is different. For example occasionally a different part of a clip is shown than in my original ie. in the timeline I have someone entering a door, but in the exported sequence it shows him approaching the door instead. Or the audio is right but shows the wrong part of the video clip.
I had a lot of syncing problems with audio and video when I captured the video but I worked around that. I only mention this in case it is relevant.
There are three video and four audio channels in the sequence – perhaps that is relevant?
Perhaps my settings are incompatible?
Any help would be greatly appreciated

It sounds like you have something seriously wrong with FCP – and I suspect the line:
[Frank Cassidy] “I had a lot of syncing problems with audio and video when I captured the video but I worked around that. I only mention this in case it is relevant.
“So, could you please give a bit more details about that. Does FCP behave this way with a different project?
Best,

Thank you for replying Jeff.
I’m unable to check if log and capture is out of sync on another project as I don’t have my camera here.
I did capture other projects before without problems.
I think the log and capture problem with this project may have been because I loaded hour long tapes in one go.
However regarding the export problem, I I just opened another Final Cut project on my computer and exported a small sequence – it seems to work fine.

One other issue could be if your audio was captured at 12 bit vs 16 bit, then the audio can drift in and out of sync.
In this case you cant just spot check and notice.
What codec, format is the video?

Thanks Anthony. I think it was captured at 16 bit, but is there any way I can check.
When I look at ‘audio format’ in the project, all the ‘sequences’ are 32-bit floating point. All the imported tape footage (before it’s put in sequences) is 16-bit integer. There is also one audio-only capture at 24-bit integer. Might this be the problem?
The video is DV-Pal anamorphic. I’m not sure how to check the codec.
I’d love to get this sorted as it is video footage of a trip made by people with disabilities to the european parliament – I recorded nine hours for them and have reduced it to a half hour film, which I now can’t export.

The problem turned out to be related to the syncing difficulties in the originally captured footage. When I re-uploaded in small chunks rather than a tape at a time these were resolved and I was also able to export properly. Thanks again for the replies.
