grain remover for vhs transfer

[dtvhacker]

what is needed a correct matrix? and anything? else to remove grain from a vhs transfer is this possible with dvd rebuilder if so what files work best and properly since alot of you guys are experts in the video field i figured id ask ya first i noticed you guys said it can be done on dvds with grain but i figured id ask first since the source came from a vhs tape first

If you need to remove grain, use Avisynth and its denoising plugins, like FFT3DFilter.

Filters are probably your best option for vhs transfer - Try the Doom9 'Avisynth Usage' forum. Try a search there for your question. There's undoubtedly multiple threads about removing grain from a vhs transfer.

For basic and resonably quick results, try using DegrainMedian() or RemoveGrain(17) for quick grain removal without effecting to much of the source, for much better overall dirt, scratch and sharpening try having a look at the function RemoveNoiseMC


I know RemoveNoiseMC works perfectly with DVD-RB Pro as I've used it while playing around with it on a very bad laserdisc to DVD transfer of very old cartoons and it did a fantastic job of removing the grain, scratches, etc,etc and also sharpening the source up, plus you still have plenty of control over the settings

Be aware that for some of the newer functions and filters you MUST have avisynth 2.5.7 installed otherwise you WILL get strange errors that make no sense no matter what you try. I know !!

This link is a collection of all the filters that is needed in one file

This has different methods depending on what you want to filter with very impressive results, but is also incredibly slow as its a filter function that calls various filters and also carries out some work of its own between the filters

So its not really one filter, but a collection of filters all doing different things to the source which is one reason why its so slow


When I say slow, I'm talking very, very slow even running dual core AMD 6000+, but time is not an issue to some of the guys that write these filters or functions, its the final quality that counts

how do i get dvd rb to use a filter iv looked around on it all i see in avs is a for a text filter

You need DVD-RB Pro, I believe (haven't used the free version in years). Go to the Options tab in the right half of the main window. Double-click "Filter Editor" and add your filters line by line, then click "Save & Exit." Then you'll see "Filter Editor (Active)" in the list. To clear the filters, just go into the editor, delete all the text, and save again.
