Color Space question

[Ripe73]

HI!

I want to clear up one thing,when i use GKnot and do the project i use YUV in Color Space but if i want to use VFAPI must i use Color space RBG when i save the project???
And what will happen if i dont do it?

[Doom9]

for gknot and in general mpeg2dec/avisynth yuv2 is a must (it is also the default).. for the rest.. it doesn't matter.. vfapi will convert to rgb anyways

[Ripe73]

okey thanks DOOM9

Hey Doom9,
Isnt yuv2 alot faster to work in then rgb though?

[Nic]

Yes YUV is faster but VFAPI only deals in RGB...

That was sorta my point, whats the advantages of using fvapi then?
What does it do that avs wont?

[Ripe73]

Some filters can only be used in VFAPI mode

Also, AviSynth is a memory hog compared to using VFAPI. On a 128MB machine, if I really needed to multitask, I'd have to go the VFAPI route. An AviSynth encode would just be too painful and the constant swapping would slow down everything, including the encode. Even on a 256MB machine running XP, with VFAPI it's much easier to use the computer for other things (100+MB memory footprint with AVS, 20MB footprint with VFAPI).
