Virtualdub always outputting RGB

[mahsah]

...even when I choose "fast recompress" and "yv12" in the lagarith codec settings, when I try to open it in megui, it still says it requires converttoyv12().

What am I doing wrong?

[neuron2]

when I try to open it in megui What does "it" refer to here? If an Avisynth script, post it.

Well, without seeing the script I can't tell for sure, but it sounds like you're using DirectShowSource when you should be using AVISource.

I don't know what version you use but i've been told the yv12 format is only well supported with vdub mpeg2 in "direct stream copy mode". As soon as u try to use a filter, it'll be RGB.
