Hello, I am rendering HD 1920x1088 footage to yuv4mpeg (video only) and use the following pipe:
mpeg2enc --verbose 0 --multi-thread 4 --aspect 3 --format 3 --frame-rate 3 --video-bitrate 28000 --nonvideo-bitrate 384 --interlace-mode 0 --force-b-b-p --video-buffer 448 --video-norm p --keep-hf --no-constraints --sequence-header-every-gop --min-gop-size 6 --max-gop-size 6 -o % This renders without problems to an m2v file. Now I have an Intel Core i7 920 processor, which is a quad core and can accommodate 8 threads. Changing the parameter for multi-thread to 8 does not make the rendering faster. On the contrary, it becomes even slower. Now I read in the link below that using the multi-thread option in fact gains very little with mpeg2enc. Does anyone have experience with this?
