avisynth -> mpeg2 which encoder etc.

[hanfrunz]

Hello everyone,

i have quicktime files of a lot of tapes, 30-40 min each. I use a batchfile to create an avisynthscript for each mov that burns in a timecode. That works very well. After that i encode each avs to mpeg2 for dvd authoring (~4.5Mbit/s). Right now i use the old mainconcept encoder to do this. But you can't do batch processing very well, i always have to load the avs, choose a preset add to list. I'd like to use a commandline encoder like mencoder, ffmpeg,... for the encoding. Can anybody recommend an encoder/presets? My goal is to encode as fast as possible, the quality must only be "okay", because it's just for preview. I use a quadcore intel machine with win xp. Right now i can get about 3x22fps with three encoders running at once. I tried mencoder with very simple settings from the manual, but i only got about 3x17fps. Are there encoders optimized working with avisynth? Would it help to convert the colorspace from yuy2 to yv12 in the avs-script or should i let the encoder do the work?

Maybe someone made the tests, i would have to do, before
