Newbie question on YUV12, AVS, V-Dub (From non-newbie)

[homerpez]

I'm not a total newbie at this stuff, but this question makes just me feel like one again. :scared:

I moved to a new machine, where I'm having to re-install codecs, programs, etc. Trying now to encode a movie from a HUGE .mkv 1080p file to a 720p one.

I used graphedit to create the filter graph (in this case, Haali -> Cyberlink H.264 Filter), this part seems to work.

I then try to use the "ConvertToYV12()" line at the end of the avs file:

DirectShowSource("Untitled.GRF",audio=false,video=true,fps=23.98)
Spline36resize(1280,544)
ConvertToYV12()

Virtualdub mod says that it does not support Yuv12 colorspace when I try to open it - where on my old machine, it did. Is there something special I have to install to get Yuv12 support in V-Dub (mod)?

If I try to open the .avs WITHOUT the "ConvertToYV12()" line, the video shows up, but I can't scroll anywhere from the very beginning of the video- it locks up.

Help please?..... :thanks:

One simple way to get YV12 support is to install Xvid or DivX.

DirectShowSource() does not allow seeking. Try DGAVCDec. Or save it out to a lossless intermediate file and then open that.

Hmm...

I think in my case it must be the first one... I do have the whole CCCP codec pack installed, but not Xvid as a standalone (which is on my old box, along with FFDshow and the rest). I suspect this may be the problem.

I do recall using Directshow source before though... and it did allow me to "seek" (I would drag the slider over and a second or two later, a picture would show up)...

Thanks for the tip on Xvid... I think this will put me back in business. Appreciate it!

It depends on the codec, some support seeking, some do not.

As you said... looks like Xvid solved the Yuv12 problem... thanks!

Seems the seek problem is solved by adding "seek=true" to the avs line. Seems I'm back in business :)
