Hi all,
I did a search for this problem and saw a few people have had it happen but I'm curious as to solutions.
Today I recorded 30 minutes of footage on my Z1 at 50i without pressing stop. I now want to capture all of that 30 minutes to my PC using Aspect & PPro at 25i.
So first I tried it with Scene Detect off - (given that there are no scene breaks anyway). And the result was a sync problem. In fact, the audio was clearly out of sync with the video from the very start of the clip.
After my research on the forums today I am currently trying it again with Scene Detect on but I doubt it will work, given that I did not press stop.
So I have a couple of questions here:
1. Why does the problem occur in the first place? (In my case the video was ahead of the audio - which seemed the opposite of what I'd have expected)
2. What is the maximum amount of footage I can capture before sync issues start to pop up?
3. Do I need to always be thinking of this problem when I'm capturing so that I make sure I press stop every few minutes on the camera so that when I capture with Scene Detect on I avoid the issue?
4. Or do I make more work for myself in Post by manually capturing 10 minutes (or whatever the maximum is) at a time?
This is quite an annoying problem and I forsee many problems in the future - I had planned to use my Z1 as an analogue->DV convertor and transfer all my home movies to my PC - but now I can see it may not be just as simple as plug it in, press record and go have a beer, come back in 2 hours and it's done...
