Hi people.
I have a little trouble capturing video. maybe anyone can give me a tip.
I am capturing small clips in full pal resolution: 768x576@25fps.
I have p3-750/512mb sdram. 40gb wd 7200. Win2000. i have BT848 card. I am using IUvcr. I know that in guide it is recommended to use VirtualDub. But i can't VD is a really cool program. I use it for everything. But i have analog cable-tv. So in VD i can't choose any channel (channel frequency). I capture in huffyuv or leseless jpeg codec. The problem is the following: Although i set a high priority to IULab's Iuvcr, anything running in background will result in dropped frames. And even if i close all the rest of process, still sometimes there're little of dropped frames, which cause to a/v desync. The only way to make this work - if i run a full defragmantation on disk, make reboot, kill all other processes and than, maybe it will be able to capture all frames.
My question is: Maybe there's some setting in windows which will encrease read/write buffer to bigger value, say, 100mb, Or maybe some program can do this? I tried other programs for capuring. The picture is approximately the same.
Thank you
