You do it right. You're movie seems to be too complex for the codec. Generally I have a file that is 8Gb per hour or movie.
BTW, Rendalunit just informed us that there is no need to use such trick anymore : avs2.5.3 as an improved Directshowsource taht handle very well MPEG1 as soon as you kill the audio.
(be carrefull : I means 1 hour of movie in
VCD resolution. Is that what you have ?)
So just use :
Code:
a=Direcshowsource("movieone.mpg").killaudio()
b=Direcshowsource("movieone.mpg").killaudio()
a++b
