Grain in VirtualDub

Post by tobias_of_doom » Thu Mar 13, 2014 4:28 pm

Disclaimer: I'm really new to this!

I've created an AVS script to use my MKV video in VirtualDub. It only has one line, FFVideoSource("video.mkv"). When I open that up in VirtualDub, there is a lot of artificating, which isn't present if I open the video up in Media Player Classic.

Here's what it looks like in MPC:

And here's what VirtualDub is giving me:

You can see what I'm talking about specifically next to the sweat drop directly under his open eye--a big block of gross artifacts (to say nothing of the color, but one problem at a time). I've looked into RemoveGrain or trying to use LSMASHSource, but the former doesn't fix the problem, and the latter won't even load (and I do have the DLL in the AviSynth plugin folder and the registry recognizes this as the correct folder). I've looked through a couple of guides, but I'm at a loss as to what to do, or why the grain it's present in VirtualDub yet not MPC.

Thanks for reading! Looking forward to your advice!

While solving with LWLibavVideoSource would be best, simply updating ffvideosource will do.
Here's the latest build: https://github.com/FFMS/ffms2/releases
Just change the ffms2.dll in the avisynth plugins folder, it will be enough.
You can also update ffmsindex.exe and ffms2.avsi if you wish.

I am having this same issue. I did what you said for ffvideosource and it doesn't seem to go away.

I can't get LWLibavVideoSource to work. Is there something I am missing?

Can you take a screenshot of the exact error you're getting?
Sometimes it's just an Avisynth install gone wrong:

Maybe try installing 2.6.0 alpha 5 (currently latests build, at the time of writing) instead of your current version, and see if that helps.

I just discovered that Handbrake fixes this. I hope that is a good method because the blocks are GONE!

Nope...you are degrading the quality by reencoding...all you need to do is update ffms2 and install the latest AviSynth version, just as mirkosp said.
