Video Capture
I had problems while capturing my HD videos from my camera to the computer. It captured all the video but there’s some audio problems. It didn’t seem to capture the whole audio. It will capture some parts then it goes mute and no sound. It usually happens when I have a long continuous video like a speech, church mass or something. Secondly, I just see these green bars(pixels?) appear to my video then goes out. Is this normal? How do I fix it? Do I need to capture the video again? or what should I do? Help! 😀

Is the capture utility reporting that there are dropped frames? Green bars and no video may indicate dropouts on the tape. Do you reuse tapes? Are you using HD tapes? What HD camera? Have you tried another capture program like HDVSplit? The more information you can give us, the more likely someone can make a recommendation.

Sometimes it reports me that there are dropped frames, but sometimes it doesnt. No I do not reuse tapes. I use new tapes everytime. I use the sony DV tapes. My camera is a Sony HDR-FX7. No, im only using Vegas’ capture system.

This is not a good sign. There should be no dropped frames. You should be capturing to a non-system drive (i.e., not C:) and you should have a fixed swap file size and your capture drive should be defragmented and have plenty of room.
Since you said this happens with long captures, I’m guessing that either Windows is reallocating the swap file (because it’s not a permanent size) or searching for hard drive space. Since HDV uses a 15 frame GOP, a single dropped frame drops all 15 which is a 1/2 second glitch. You don’t want to drop frames with HDV.

If the drop-out cannot be seen on your cameras LCD when playing back then it’s not the tape. If it can, then I would seriously consider using HDV tapes which are more robust and less prone to dropouts. Today they are only a few dollars more and worth the peace of mind.

Is HDVSplit freeware? It appears to be.
If so, can I use it at my company?
I’ve used it in the past and found it performed better than Vegas’ capture utility where I’ve also experienced drop outs without frames being reported as dropped.
During long captures, scenes will occassionally split even if scene detection is turned off and I’ll lose a few seconds of video.
I’m often able to just recapture the section that was dropped and mix it back it but it’s time consuming.
If HDVSplit is ok to use commercially, I’d rather just use that.
thx!

Yes it does appear to be. There is no way to buy it.

That’s a question for your company lawyer.

I assume you are referring to the Sony HD capture utility. Yes, that’s a known bug. 🙁
