VirtualDubMod Crash W/HuffYUV

Postby SrgtWilco » Tue Apr 03, 2007 11:53 pm

Okay, so when I export from Premiere Elements using HuffYUV to compress, and then load that file into VirtualDubMod, I run into a problem: Whenever I hit a certain frame, the program will freeze and say it has to close. Another scrap with HuffYUV is that some of the frames I did look at had these red bars in about the upper ten pixels of the screen...and lastly, putting in an avisynth script such as this:
#ASYNTHER Default (AVISource)
AVISource("C:\Documents and Settings\Dad\Desktop\Test - HuffYUV Compression.avi")
TFM(pp=0)
TDecimate(mode=1)

will get me an error message reading "Avisynth Open Failure: TFM: YV12 and YUY2 data only"

Help on any (or preferably, all three) of these problems would be greatly appreciated.

All right, well I'm not sure about this, but generally you're video editing program uses the RGB32 colorspace. TFM only supports either the YV12 or YUY2 colorspaces. Thus, you'll need to change the colorspace of your vid before using TFM. Add something like ConvertToYV12() to your script before you perform the TFM

Err, wait, actually I think ConvertToYV12(interlaced=true) since you're dealing with interlaced footage

What's your video's resolution? Preferably, both height and width should be even multiples of 16.

Also, you can force HuffYUV to use YUV mode by setting its RGB compression option to "Convert to YUY2", which will prevent you from having to convert it later in AVISynth.

And barring all else, sometimes you can get a bad export. Simply following the advice of the others should take that very random variable out of the equation.
