Jerky playback of captured DV files

[markyd]

Help.....I'm pretty new to this, have searched the forum but can't find an answer to my question anywhere.

Is jerky/jumpy playback of captured DV on the PC due to the quality of the capture (even when no dropped frames are counted during cupture)?

When I capture DV video to my PC it ends up looking jerky/jumpy. It looks like there are dropped frames, but no dropped frames are counted during capture.

I've tried Premiere pro 7.0, WinDV and DV Studio 9 and all seems to do it to some extent. Premiere seems to do this more than WinDV or DV Studio9, but I'd really like to use Premiere.

I've tried 2 firewire cards, a VIA chip based one and a Pinnicale one, and it happens with both.

I've tried shutting down antivirus etc.


Studio9 with the Pinnicale card gives least jumpy capture, but it looks like there are horizontal lines in the video, is this what people call comb lines? Is this a problem?

PC is
AMD Athlon XP 1800
786mb RAM PC2100
7200rpm, ata133, 160GB HD
so I'd have thought it would be up to it?

try to use Ulead videostudio, you can download it and try it.

looks like a set-up problem, but try it anyway. leave the field as LOwer field first, that might be a problem too.

your pc is good, that is not the problem, don't need e better one.

I'll occasionally see jerkiness when previewing even with a 3ghz and 1mb of ram. Most likely your system is choking.

You could hit ctrl-alt-delte and see how much of your CPU is being utilized when it's being previewed. Since evething else is pretty good on your system that is probably the culprit.

In any event if it's just a case of your system not having aenough juice for previewing it won't carry over to the final files.

The horiziontal lines are because video for TV is interlaced. It's actually parts of two frames instead of a single frame. Here's an example, look at the singers face, it will be more evident where there is movement:



Good place to start for some good information is digitalfaq.com Many of the basic concepts of video are explained there in detail such as interlacing.
