tmpge noise filter

[Reaper88]

I was wondering how many of you use tempge's nosie filter when you covert vhs capture's to mpeg2? Also is there a noticeable difference when you use it?

Noise is a major "consumer" of bitrate, especially with regards to captured video. Noise reduction frees up bitrate to be used by the rest of the video, giving a better picture. So when you use noise reduction it may not be readily apparent that there is in fact less noticable noise, but it can still improve the overall quality of the video. Try a few test clips with and without noise reduction, but look at the overall picture quality.

Thanks for the info. I am running some test clips now and man tempge is alot slower with the noise filter. Time isnt an issue for me so it dosent matter.

I, personally, prefer all the options of different VirtualDub noise filters.

And, yes, depending on the source, of course, you can get some almost remarkable results with the filters.

I've used the noise reduction filter quite alot with some very good results on material captured from VHS tape. The best settings vary according to the type of material, so it's best to try a few settings on a short section. I had some settings which I used for doing stuff for the kids which didn't look so good when I used them on a film.
It really can be very slow though; I've had up to 30x realtime for encoding, though the results have been worth it. My computer isn't the most up to date, and I probably haven't got all the settings optimised, before someone points out that it should be much faster than that!

When i set the noise filter in tempge I used the perview-zoom and played with the settings till i found what I thought looked best. I am doing a short clip and will author and write it to a RW to see how it looks. My computer isnt the newest either. 1.2 ghz athlon, and yea my encoding is very very slow but it will be worth it if it looks better when it is done.

If you are capturing and then encoding to MPEG-2, then you are probably capturing to avi. I would recommend you to use VirtualDUB to make a pass on the captured video, while at the same time trim out unneccecary segments (start-end and in the middle).

VirtualDUB has an extensive filter library and plug-in filters are even more and better. And VirtualDUB will be much much faster in processing to clean video than Tmpgenc. Tmpgenc filters are very very slow.

It may be that you need to make an extra pass through VirtualDUB, but the overall time required will be much less if you do it this way.

The absolute "best" way to do it is make a pass through VirtualDUB and use frame serving to feed the output directly to Tmpgenc. Can be done and it's even faster, but I've never been able to frameserve reliably every time so I dropped the case there.
