Captured TV Program is choppy

[ione]

Hi, I am new to analog capturing. I have recorded a program on TV using Sony DV TRV-33 (alongside analog VCR and TV). When I played back the program on the camcorder, the output was excellent. However, upon transcoding (using firewire and WinDV), the output mpeg file was choppy (for both audio and video). I wonder what's wrong: I have many HD space (41GB.) On the other hand, nothing seems to be wrong with the firewire or PCI card, as I have tried to transcode other footages taken with the camcorder---and the output was excellent! Please help. Would really appreciate your response.

Firewire and WinDV will only create a DV-AVI file. What process did you use to encode to mpeg? List tools and any guides you followed.

sorry i meant to say AVI as my output file. i used one of the WINDV guides on DVD-guides.com - (It's how to capture video from DV guide). http://www.dvd-guides.com/content/view/33/59/

WinDV does not transcode - it simple copies the video data into an avi container on your HDD.

When you transferred the footage, did WinDV drop an frames ?
When was the last time you defragmented your HDD ?
What are you using to view the avi file ?

yes it dropped A LOT of frames. last time I defragmented my HDD was just this week. I am using Windows Media Player or VideoLAN to view the AVI. hope this helps.

Dropped frames = choppy playback. Each frame dropped is one you don't have in your video.

Thanks for the link. I followed what most of the thread suggested (defragment, remove internet/LAN, etc.) but to no avail. Just to double check, I redid copying the recorded DV footage that I successfully copied using WinDV from before.... And this very same footage is now dropping frames. So it's not just the analog source that's dropping frames now. What could have gone wrong? When the very same DV footage wasn't dropping frames a couple days back?

Just a long shot. I had similar problem. I opened my case and my fans were choc full of crap.
CPU was overheating.
