hi,

I recorded some car races from NTSC TV signal, the quality is awesome in
MPEG. However, i had to split to file into several pieces & now when i
join them & try to save with VirtualDub, anything in the video which is
moving gets interlaced (for lack of a better word). whatever object is
moving gets white lines across itself. Happens with different encoding
programs, different video files. I've come to the conclusion that it is
the codecs i have installed. just the way they encode by default. Not
meant for fast motion. i could be wrong.

anyway, that's why i need to know what is the best & free fast motion
video codec out there.

thanks

I'd say that interlaced is a pretty good word for what you're seeing.
If you're intending to view on a PC, then deinterlace it.

Try increasing the video bitrate setting.

What you're seeing is the interlacing properties necessary for proper TV
display. If you intend to watch your videos on a TV, leave them alone.
They will look perfect on a TV. On a computer screen, they will have lines
through them on fast motion, but on TV they will look perfect. If you never
want to watch them on TV, then choose a different codec when you capture;
one that de-interlaces the video, such as mpeg1. Alternately, get an
program like WinDVD 5 that will play the interlaced file as if it were
de-interlaced (progressive mode).

Brian thanks for replying. i dont think it's bitrate problem because i
captured it at DVD quality, something around 8000 Kbps.

Will, thanks for replying. I've looked for an option to deinterlace
with Virtualdub with a few different video codecs, but nothing.
couldn't find it.

Sanman, thanks for the detailed explanation. I dont plan on watching it
on TV, onyl PC. I recorded it as an MPEG, not sure if MPEG1 or other,
though.

thanks again, i'll get back to you with my results.

You described it as "interlaced", and probably that's exactly the
problem, namely: that mpeg-2 supports interlaced, but Avi doesn't.
When watched on TV, it should look alright, but not on the computer
monitor.
