Here's my post-render workflow:
input: rec/*.tif rec.wav
phase0: convert to png
mkdir png
cd rec
find -iname "*.tif" -exec convert {} ../png/{}.png \;
cd ..
phase1: lofi ogg
ffmpeg2theora -p videobin -f image2 png/%08d.tif.png -o rec-v-ld.ogg
oggenc -b 96 -o rec-a-ld.ogg rec.wav
oggz-merge -o rec-ld.ogg rec-v-ld.ogg rec-a-ld.ogg
phase2: hifi ogg
ffmpeg2theora -f image2 png/%08d.tif.png -o rec-v-hd.ogg
oggenc -b 192 -o rec-a-hd.ogg rec.wav
oggz-merge -o rec-hd.ogg rec-v-hd.ogg rec-a-hd.ogg
phase3: dvd mpeg
ffmpeg -f image2 -i png/%08d.tif.png \
-pix_fmt yuv444p -f yuv4mpegpipe - |
y4mscaler -I sar=1/1 -I bg=RGB:255,255,255 \
-O preset=dvd_wide -O bg=RGB:255,255,255 |
mpeg2enc -f 8 -q 2 -b 8000 -o rec-v-dvd.m2v
twolame -b 224 rec.wav rec-a-dvd.mp2
mplex -f 8 -V -o rec-dvd.mpeg rec-v-dvd.m2v rec-a-dvd.mp2
phase4: lossless archive
tar --create --owner=0 --group=0 --gzip --file png.tar.gz png/
flac --best --verify rec.wav
notes:
/usr/bin/oggz-merge used to be called /usr/bin/oggzmerge
ffmpeg* probably supports tif directly, maybe it'd be quicker...

[PD] encoding tif sequence (GEM pix_write) on linux
