Capturing Video to Disk with lossless frames
ok. I've tried several different capturing programs off the net and get the same results with them all. When I try to capture a 2 hour video from my camcorder, I get frames being dropped. So, by the end of the recording, my audio out of sync with the video by a varing amount (a second to several seconds). I want to just start the tape, walk away and come back to a recorded set of files.
My PC is a 900 mhz, 40 gb drive with 20gb remaining, nothing else running, matrox g200 capture card, clean HD, defragged. I can record about 15 minutes with only a few dropped frames, but it keeps building up.
I am trying to eventually get the video onto a CD in VCD format. (no problem there)
Is there such a thing as a capture program (hopefully free) that will compensate for dropped frames so the audio doesn't get out of sync by the end of 2 hours?

7200 is going to be borderline and you dont want to blow the bucks on it and find out its not gonna cut it. I dont think they make a 10k rpm ATA drive but 2 ATA 66 drives together could do the trick.
SCSI drives get up to 15k rpm these days.
Yep, and yesterday adaptec released a scsi-320 card. Dunno where youre gonna find drives for it though..heh.

So, does this mean that video capture software can't compensate for the dropped frames?
That's right. Imagine trying to drink all the water coming from a fire hydrant. You'd get a mouthfull and before you could swallow it, you'd get another mouthfull and it doesn't stop. It backs up to a point where you just have to spit it out....A dropped frame. Even the best software will choke if the HD cant keep up.

What about compression? Can the video be compressed (using CPU) when capturing - this would require less HD resources then, wouldn't it?
According to the capture software (most of them) the cpu is only utilized ~10% when capturing.

Some input devices can do on the fly compression but by doing so youre losing quality which is generally a bad idea.
You might want to try VirtualDub. You can download it at www.vcdhelp.com.
It doesn't use the native windows code for capturing and gives you a diagnostic for your system in order to determine optimum settings.
Worth a try...

Oh and there are lossless codecs out there - try a search engine.
That way you won't lose quality and will be writing less data to your HD...

you need to free up more hardisk space or get new harddisk and use the adobe premier 6 to capture a series of file 20 Min Each one of them.
But I recommend to get a SCSI Harddisk cause its faster than the IDE harddisks.

Thanks Weed. For the short term, I'm going to capture smaller files at one go and just merge them together. A bit more work, but what the hey.
