Need help with denoising for VirtualDubMod

[8thSin]

I want to rip a DVD and add SSA subtitles using VirtualDubMod. There are a lot of random white dots on the video, and the original video seems grainy.

I know next to nothing about encoding, but I have a friend who does, and he sent me a sample.
The problem is, his computer runs on Linux, and he uses Mencoder, which seems to have limited support for SSA subtitles.

This is his setting

mencoder -oac copy \
-ovc lavc \
-ffourcc DX50 \
-ofps 24000/1001 \
-vf softskip,crop=704:456:8:8,scale=704:400,eq2=0.9:0.9:0:1.05 \
-lavcopts vcodec=mpeg4:autoaspect:nr=150:mbd=2:v4mv:trell:vpass=1:vbitrate=1600 \
-aid 129 \
-o /dev/null dvd://1

I have no idea what that means, but if someone can help me translate those settings into VirutualDubMod, that would help a lot.




I found many denoising filters in this page (http://www.thedeemon.com/VirtualDubFilters/detailed.html#30), but I don't know which one is the best. My friend tells me his filter is "decimation with filtering".

Here's a small segment of the video ripped with VirutalDubMod with no filters, single pass.

And here's my friend's rip, 4 pass, with "gentle denoising and gamma filter of 0.9", it's much clearer and richer color.

Please tell me if there's some other filters you think I should use to make it look better.


Thanks in advance.

You can try my Smart Smoother filter.

He also resized to width=704.

Bumping the color saturation a little helps too. You can use my Hue/Saturation/Intensity filter for that, or the internal HSV filter.

My filters are here:

Thanks for the recommendation. I will try it.
