Could that explain why I can't get a smaller m2v file when increasing

Ok - so it's not going thru an analog conversion and does not have
analog noise to worry about.
Hello everybody,
The Cinelerra version I use is the "Community Version".
There's a problem with field order with the version I use, and that's
ONLY in batch rendering mode. The field order information of the project
wasn't use correctly when rendering in batch mode. I don't export as
MPEG2 from C

Note that at least in cinelerra 2.0 there's an checkbox in the "mpeg2"
rendering dialog box which says something like "bottom first field o

Pick a number between 2 and 8 :-) There are higher values (up to 31)
but in practice they're not used (not often).
Folks think of "-q" as being "quality" and in

But I want a magic "use this for high quality" switch! Can't I please
have a magic switch? I think it would make my videos so much better without

Probably not a big difference. The lower limit is mainly used by
mpeg2enc's dynamic GOP sizing logic. If 6

Hello,
I use mpeg2enc and mplex to create my DVD from videos made with
Cinelerra. Cinelerra outputs an YUV4MPEG stream which I encode "on the
fly" with mpeg2enc. Here's the pipe I use :
/usr/bin/yuvcorrect -T INTERLACED_BOTTOM_FIRST | /usr/bin/yuvscaler -v 0
-I ACTIVE_702x560+8+8 -M BICUBIC | /usr
