Try somewhere like 2000-4000 kbits/sec for 352x288 type resolution, 4000-6000 kbits/sec for 720x576. > The is captured with the default options of ffmpeg, I've > tried ofthers, but none of them seem to be able to sync the audio > and video. > So what format would you guys use, if you had the following > requirements: > > 1) Cheap to decompress (300Mhz cyrus) > 2) Expense of compression irrelevent (2 1.2GHZ Athalons) > 3) Able to fit through a 100Mbit ethernet pipe > 4) As close to lossless as possible. > > I guess it can be done, 'cause I'm told that with TIVO, you get > good quality video. What do you think? Well - I use mpeg1, but you must have good input video quality and have to accept that you need an adequate bit rate. If I'm keeping stuff I recompress into Divx4 - mencoder (part of mplayer) is working well for me. Shrinks my files to 1/3rd original size, but Divx compression is much much CPU heavier than mpeg1.
