What format are you trying to capture and how are you doing it (firewire, other)?

Thank you for responding :)
Camera is Canon HV30 and I'm running windows 7 and yes I'm using firewire too. I'm trying to capture HDV video from tape.
Living in Norway I'm using PAL system.
I can capture the whole tape or parts of it by start/stop.

Capturing HDV by setting TC in/out points is not something I think will work, at least not over firewire.

So if I understand right, it's only capturing DV I can use timecode?

Yes, DV is all independant frames, HDV isn't.
You need to capture a whole GOP of data from a HDV tape to ensure all the frames can be decoded. That creates a problem if your in/out points are not aligned to the GOP.

The same utility that captures HDV also is used to capture over SDI. The latter should work just fine with TC but HDV VCRs with HD SDI interfaces are not cheap.

Thank you very much for explaining it all to me.
First I thought I did something wrong, but I understand now.
I have to save some money to buy me some interface stuff :)

"I have to save some money to buy me some interface stuff"

A few years back I bought a Sony HVR-M15P VCR and I'm very happy with it. It will not capture any tapes that contain progressive footage, no problem of course with "PsF". Sony have since released a new variant of that VCR which seems to handle most but not all of the possible ways HDV is written to tape.

A similar VCR with HD-SDI and 9 pin control is way out of my price range. Add to that the cost of the HD-SDI interface card for the PC and the disk arrays to handle to data rate and it all gets a bit silly.


All of that said it's not a big deal as I've never found a need to batch capture anything.

I have to look into that Sony HVR-M15P VCR.
And again, thank you for being so helpful.
