fixing grainy capture?

[downer]

I am capturing a vhs->advc-50 with iuvcr.

It seems that the capture has no dropped frames but the avi produced seems a bit grainy. Is there something I can do to clean this up maybe in TMPGenc befroe i encode it?

I know avisynth might be good, but i am not sure how to use it. How about VirtualDub?

Thanks

The recommendations I've received from this forum is to let VirtualDub do any resizing and filtering. Just what I've heard.

Try the filters in virtualdub, the temporal filter helps a lot with tv captures.

Just remember any filters used in vdub use RGB colour space. If you cap in yuv vdub must convert it first to RGB. Avisynth works in both colour spaces and the filters for clean up of grainy or "NOISY" caps is just as good if not better than vdub, skipping the conversion can speed up encoding times
Just for your info

I have no problems using virtual dub filters on YUY2 mjpeg captures.

What filter do you use in Avisynth to clean up noise ?

For caps from VHS I use: temporalsoften(5,2,3)
For noisy caps off broadcast television I use:_2DCleanYUY2(0,4,2,2,0,2,2)
Don't forget 2d clean uses a seperate .dll you must load seperatly
