Quality Test - Pulseman (Wii VC/Genesis)

under video compressors i get "normal" for both huffyuv and ffdshow codec/encoder.

under directshow filters, ffdshow video decoder is cranked, 0xF77A0000. "avi decompressor" which i'm assuming handles vfw stuff like huffyuv is only at normal. so i guess installing huffyuv won't solve people's problems ... unless we also lower ffdshow's merit, lol.

I am encyclopedia

Cables arrived. Just wanted to check in one last time before I start recording attempts.

Quote:

The pixel_type parameter (default "YV12") allows you to choose the output format of the decompressor. Valid values are "YV12", "YV411", "YV16", "YV24", "YUY2", "Y8", "RGB32" and "RGB24". If omitted, AviSynth will use the first format supported by the decompressor (in the following order: YV12, YV411, YV16, YV24, YUY2, Y8, RGB32 and RGB24). This parameter has no effect if the video is in an uncompressed format, because no decompressor will be used in that case. To put it in different words: if you don't specify something it will try to output the AVI as YV12, if that isn't possible it tries YV411 and if that isn't possible it tries YV16, etc ...

On a Win7X64 VM with only CCCP installed:

_source.avs:

Code:

avisource("pulseman.avi", pixel_type="YUY2")

= No ghosting for this particular video.

Of course, if you have a true yv12 video, forcing the pixel type isn't going to magically fix things. Though it's not a perfect solution, it may be better than nothing. So between this, getting people to install the huffyuv codec, and quality tests, we may end up with few problems. What do you think?

is there a foolproof way to tell the colorspace of a given input video? and then force decompression using that colorspace every time. so like norichan avis are all yuy2, and it determines that, and then sets pixel_type to "YUY2"?

Not that I know of.

After thinking about it some more.. I would rather not start forcing pixel types. Who know what other problems could come up. I think we should just include the attached huffyuv+installer and tell people to make sure to install it with Nori.

There is an INSTALL.bat and UNINSTALL.bat in the same folder as the huffyuv 2.2.0 files. You must run-as admin for it to work, since it's writing files to windows\inf and windows\system32 / windows\syswow64. I included an isAdmin check so it shouldn't mess up when installing the huff files.

I tested in virtual machines for Windows XP Pro/ Vista Ultimate / 7 Ultimate in 32/64-bit versions for each and it seems to work. avisource("pulseman.avi").info shows yuy2 once the codec is installed.

yo ballofsnow, have you gotten your installer to work on windows 8? ive even disabled UAC and tried right clicking it and running as administrator, but it still complains about not being administrator.

Windows 8 deprecated a command that was used to check if admin. I just made it a warning now that you need to be admin. See attached, works on my Win 8 x64 system.
