Anybody had any success using the GIMP-GAP for encoding mpegs of a
reasonable size?   I downloaded it and tried it out on some 1200 frames i
had archived from some playing I'd done several years ago, but it kept
either crashing or creating mpegs that were over 3 times the size I'd like
to see.

The stills are about 77.4 megs worth of .pngs, 320x240.   Cmpeg created a
5.6meg file from that.   Granted, that file is lossier than the 18 to 22meg
files that GIMP-GAP produced but control over size is one of the things I'm
looking for.   It seemed like anything I tried to reduce the bits/sec, play
with parameters etc just made the file bigger (or the GAP to crash).

Any ideas suggestions?

Thanks,
Charles

PS,
Correct me if I'm wrong but I'm guessing the GAP is fairly new based on the
file dates at ftp://ftp.gimp.org/pub/gimp/plug-ins/v2.2/gap/ and my not
seeing anything on it when I did a search in these newsgroups.

Here's from the readme:
The GIMP Video menu 2.2.

The GIMP-GAP (GIMP Animation Package) is a collection of Plug-Ins to
extend GIMP 2.2 with capabilities to edit and create animations as
sequences of single frames.

(note i never used GIMP-GAP)
it probably stores the video as a sequenc of seperate images becouse that
makes editing a 1000 times simpler. It alse means there is no
frame-to-frame compression so the resulting animation is just as big as the
input images, unless you set it to a lower quality.

these days I juse a simple linux command:

ffmpeg -hq -b 1000 -i "filename%3d.png" -y "filename.mpg"
(high quality, 1000 kbit/s)
