Analogue Capture (Drop frames problem)

[Darwin]

Hey guys,

My capture system:

WinXP SP2
P4, 3.4Ghz
Radeon x800 Pro
1GB pc3200 Ram
Pinnacle Mediacenter 300i capture card.
620GB (3x hard disks)

First of all i've read the newbie guides here at doom9. However, my "capture" problem persists.

I've got a camcorder (an old one) and i'd like the contents of the old tapes to be captured on my computer. The best quality possible (got more than enough space :) )

camcorder---cable---computer---virtualvcr---output[file]

I got connection though an analogue tv cable...it's fine when i see the video being played in virtualvcr, however when I start recording the video to my system, the video seems to lag a bit once in a while and i can see that my frames drop, which is very weird cause my system should be able to do the job fine. Here's a log of virtualvcr:

Frames Dropped2: 359!! That's so much that audio/video goes out of sync! the file was about 40gb, but i don't really care about size i just want the video to work (without the frame drops) at my computer after my capture :/

btw. right when i turn on recording a few green flashes occur - and that would also show in the final video.. :/

Feel free to ask for any other system stuff...Thanks for any help provided.

Well I gave up doing AVI capture just because of this problem. With ATI MPEG2 hardware encoder there is never any dropped frames,NEVER!!

But back to your problem. For $10.00 you can buy Leadtool's MJPEG encoder which I have used with VirtualVCR which is excellent. No dropped frames can be done in other .AVI codes but requires much fine tunning of your complete computer, bios, and operating system. Use Win2000Pro instead of XP.

To lead you by the hand is really not possible. I wish you good luck.

Could be a lot of things, but often it's Windows' Power Options trying to turn things off or other background programs using CPU. Make sure the Display Properties->Screen Saver->Monitor power->Power options are set to "Always On" for "Power Schemes" and "Never" for the other three boxes. Then delete anything you don't need starting with the PC from the Start Menu->Startup folder. Then use the Run box on the Start Menu to type "C:\WINDOWS\regedit.exe" and go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run and delete any entries under this for third-party software you don't need starting with the PC. Make sure the "Resample Audio dynamically" box is checked in VirtualVCR. Reboot and see if you still get frame drops.

Thanks for the advices..

I bought the PicVideo Mjpeg codec, so now i hope everything works out.

I'll get back to you in this thread with my results
