I have about 40 Video8 tapes that I need to transfer to DVD and would like to find a good filter to use in virtualDub to denoise. I have transferred tapes before but have never used any filters so have no idea about what would work best. For info, my workflow is as follows:
Playback via Sony CCD-TRV78E > Capture via Canopus ADVC110 > Capture to AVI with WinDV > Denoise in Virtual Dub > Encode to DVD via TMPGEnc Video Mastering Works 5

What kind of noise? Can you give us a short, unprocessed few seconds of sample? If you don't know how to do this with VirtualDub, let us know. Otherwise, one can only be very general:
Camcorder Color Denoise
NeatVideo
temporalsmoother ( Virtualdub built-in filter)
Many image problems like noisy interlace, compression artifacts, etc., that result from capturing analog source to DV-AVI can't be fixed without degrading the image. More are listed here http://rationalqm.us/mine.html#virtualdub and here http://www.infognition.com/videoenhancer/filters.html.Your best bet is to try to learn some basic Avisynth if VHS-to-DV is the only way you can capture the source.

I don't suggest NeatVideo. It's too aggressive, even on the milder settings. You quickly get "plastic-y" video.
CCD is ideal for chroma noise.
There are several denoisers, both temporally (interframe) and static (intraframe).
But without seeing a sample, I won't even hazard a guess. Video varies far too much for it.
Avisynth may also be a wise move. Again, it depends on the video errors.

Thanks for the replies. Sorry for not posting a sample yet. I have been waiting for a new power supply for my camera. I have recorded a sample but just realised that the video 8 tape I used was the only one out of the 40 that was recorded in long play so it's probably not the best to use as a sample. I will record from another tape but I will be away for work for a few days. Will post a sample on the weekend.

Sample attached. I can redo if it's too short or not an appropriate sample.

On a video like this, the noise is more grain-like than noise-like. I'd be very hesitant to remove more than a limited amount.
- Perhaps a 2-frame radius on a temporal NR in VirtualDub (Temporal Smoother filter).
- Then mask the overscan.

Is it normal that the video has like transparent vertical lines through it which makes the edges jagged? What causes this?
