Log & Capture Not Producing QT File
Here’s a weird one and a first for me. I hope someone can help as I sit here with a deadline freaking out!
I am re capturing data from a FC Project file. Batch capture functions fine (except for that irritating WARNING about the devise reading non-drop and settings are drop frame.) Format is DVC Pro 50 1080i60 HD.
Here’s the issue. When I batch capture say, six one-minute files from the same tape, some are fine but some have audio out of sync as much as three seconds. It’s random. No pattern.
So, I’m trying to trouble shoot the problem. I re boot in safe mode, then re boot full. I trash the FC.plist file and the three cashe files in FC User data folder. Now, not sure if this caused the BIG issue, but now when I batch capture, or log & capture, FC performs the task, I see the video playback during capture, everything looks normal. BUT, the QT file is unreadable. The media clip still has the red slash. And if I drag and drop the QT file from the directory, FC rejects it as an invalid file. It also won’t play back on its own through QT player. It’s just a black picture.
I’m stumped. ANY fast troubleshooting input will be greatly appreciated. I’m even looking for phone support for a fee if necessary. Deadlines suck!
Thank you!

The format can’t be DVCPro50 1080i60. DVCPro50 is SD. The format could be DVCProHD 1080i60. Maybe there’s a mismatch between the deck settings and FCP input settings.
Or maybe there’s video breaks in what you’re capturing. Another cause of audio sync.And, maybe the clips were logged with a certain number of audio tracks and your capture preset or sapture settings are capturing less or more tracks.
If you capture afresh, not batch capture a sequence but log and capture, does FCP make a file that’s fine?
And finally, is your capture disk a local and MacOS Extended drive? Not NTFS or FAT32 or a network drive? Double check this.

I will do my best to answer, as I am a layman with this. Bear with me!
Not sure where I got the term DVC Pro 50. Was always in my head. The Tapes Are DVC Pro. The recording is 1080i HD shot at 60 fps.
I have a hunch about the sync problem, but I cannot replicate it to confirm because of my now bigger problem:
If you capture afresh, not batch capture a sequence but log and capture, does FCP make a file that’s fine?
It did for a while and I must have changed a setting because now I cannot log an in/out point and to a single file capture. HOWEVER, if I insert another DVC Pro tape, open another show project (this one 720p 23.98), change the “capture/input” setting accordingly, wa-la, it captures fine. I have something mismatched in the settings when I tinkered trying to figure out the audio sync issue. But I went back through and thought I returned everything to the way it was when it was working.
I realize I’m not giving you much to go on. I wish I could just start a new project file and quit chasing it, but the audio/video presets seem to stay where they are when I start a new project.
Sorry I cannot answer at a higher level for you.

What deck are you using? And are you connected to the deck over Firewire? Or through a card like Blackmagic or Kona?

The machine is (or was, it was a rental and since been returned) a Panasonic AJ-HD 1400.
I have a BetaCamSP deck and Blackmagic card which I am going to hook back up and see if it will perform a digitize edit.
