hello, here is a "benchmark" on MacOS 10.4.9 PPC with 1000 frames =20
(decoder ffmpeg / encoder mpeg2enc):
2 versions : 1.8.0release and 1.9.0rc2

Computer:
uname -mpsrv
Darwin 8.9.0 Darwin Kernel Version 8.9.0: Thu Feb 22 20:54:07 PST =20
2007; root:xnu-792.17.14~1/RELEASE_PPC Power Macintosh powerpc

command line:
ffmpeg -v 0 -i '/Volumes/Video_4H/_A_ENCODER/_BA_VO/the_invisible-=20
fte_h.640.mov' -aspect 4:3 -r 25:1 -s 720x576 -vframes 1000 -f =20
yuv4mpegpipe - | mpeg2enc -v 1 -f 8 -a 2 -b 7000 -q 5 -R 2 -P -o =20
test_mpeg2enc_180r.m2v -F 3 -I 1 -n p -z b -g 9 -G 15 -S 9999 -s -M 2 =20=

&> test_mpeg2enc_180r.txt

-------------

Bench with verbose -v 1:

v1.8.0 release : 132"
v1.9.0rc2 : 101"

-------------

result is good (no artefact but with -q 5), you'll can check them =20
here (16Mo each one):
the two verbose(s) are on my site too (some Ko only)

PS: I took the 1st video I found (don't worry about "jerks" or =20
interlacing warning, it's an progressive NTSC encoded in PAL ;-))

bye
