Removing Grain/Noise From Entire Disc?

[meeshu]

I have some DVD's (with episodes of TV series) which are just starting to fail, so I'm backing up these discs before it is too late.

Each DVD disc typically has four episodes. Some TV series episodes seem to have grain/noise in them, and I'm wanting to remove (or at least minimize) them.

I'm using DVD Rebuilder when reducing the DVD-9 DVD down to DVD-5 size DVD as required, although some DVD's may be "copied" to another DVD-9 disc as required also.

Ideally the grain/noise filtering should be done for the entire DVD disc with four episodes while copying or reducing via DVD-RB, and without having to extract each episode (manually) and applying filtering to each episode and then having to re-author the entire disc.

So the filtering should be entirely automatic after starting the copying or reducing process (a one click process).

Is this possible? If so, how?

A manufactured DVD shouldn't fail for at least 100 years unless they're improperly stored or handled. Are you sure your drive or player isn't what's failing?

You're definitely not going to find any one-click solution.

Both the standalone DVD player and computer DVD writer have problems with some DVDs. Most of my DVD collection play fine, it is just a few DVDs that are starting to cause playback issues.

The suspect DVDs have not been mishandled. There are no indications of scratches, smudges, nor marks of any kind. The DVDs have been stored within their original cases.

It is understood that some good quality DVDs may last up to one hundred years, but if some of my DVDs are not of good quality and/or were not manufactured properly, then their lifetime may be considerably less.

Regardless, some DVDs have grain/noise due to lower quality source, and it is this grain that is wanted to be removed.

Actually there seems to be a one click option that appears to be working. On experimenting (and it is still ongoing) using DVD-Rebuilder (on one click process mode), and using grain/noise reduction/removal plugins and scripts for AviSynth, it has been found that DVD-RB and AviSynth does indeed minimize/remove most grain/noise from the DVDs! So it seems I may have answered my own question.

Just a bit disappointed that there have not been more comments from others with more experience in using DVD-RB and/or in noise filtering. I know that there are, or were, some members who are experts or quite experienced in their fields of filtering and DVD-RB (and other similar programs) use.

If you removed the above qualification you'd probably be offered loads of suggestions.

I can't speak for everyone but I've not created/authored a DVD video disc in years, unless I needed a format for a family video grandma could play, and I've never created a Bluray video disc.
Many here would do exactly what you don't want to do. Rip out the individual episodes and output standalone files for each such as MKV or MP4.

Can you add your own Avisynth filtering to the process when using DVD Rebuilder? I've never used it myself.

Depending on the picture quality and/or amount of noise, I'd either use QTGMC (http://forum.doom9.org/showthread.php?t=156028) in progressive mode for denoising (assuming a progressive source), maybe followed with a moderate amount of LSFMod (http://avisynth.nl/index.php/LSFmod). Or there's SMDegrain (http://forum.videohelp.com/threads/369142-Simple-MDegrain-Mod-v3-1-2d-A-Quality-Denoising-Solution), or TemporalDegrain (http://avisynth.nl/index.php/Temporal_Degrain). The first is a deinterlacer but it makes a very good noise removal filter in progressive mode.

All noise removal will be some sort of compromise between removing noise and removing fine detail, the idea being to keep the ratio as favourable as possible.
Some small examples attached to this post (http://forum.videohelp.com/threads/373389-Noise-Reduction-Advice?p=2404032&viewfull=1#post2404032) of a noisier than average source.

Most people here like to 'fiddle' with video, so you may not get a quick fix for what you want, a non video specialist site would be more likely
to provide a quick fix.
I can only suggest taking a look at HandBrake or one of it's offshoots, very easy to use (last time I tried it about 3 years ago), and very capable,
dont know (but assume) that there is some kind of denoise control included. (I really was impressed with what handbrake could do), If I recall
correctly, it could re-create a DVD including all menus to output MKV, dont know if can re-create DVD ISO but might be worth a look at least.

EDIT: Handbrake is closest thing that I have seen as a 'one click fix' type thing for DVD and zero prior experience in video editing.

(In my opinion) denoising should be done carefully, with attention to detail and applying only just enough processing to help the video without overdoing it. If you denoise en masse with some 'average' setting, half the videos will have too much noise reduction, ie unnaturally smooth, time-smeared, color-banded, etc.

You are gonna a get a lot (if lucky) more answers like that.

EDIT: Mind you, you mention DVD Rebuilder, and then say

kind of contradictory.

Settings=>Options=>Filter Editor
In the opening editor you can insert your preferred avisynth noise filter(s).

But maybe the avs filter option is only available in the DVD-Rebuilder PRO version, I am not sure.

Comments noted, thanks.

Using DVD-RB Pro version.

The procedure for entering scripts within DVD-RB for use with AviSynth is already known, thanks. The current degrain/denoise scripts were previously entered via DVD-RB Filter Editor, and the results so far seem to be quite good. Results are certainly much better than the quality of the original videos.

The "one click" procedure is done via DVD-RB after setting up various parameters including AviSynth scripts. Then after clicking the "Backup" button, DVD-RB will then automatically prepare files, encode them, rebuild them, and either save resulting video in ISO format or burn the video directly to disc. This is all done without requiring any further input.

I'll bite.... what noise filtering did you end up using?

The script is based off this (http://forum.doom9.org/showthread.php?t=171328). Full credit for this script goes to the original author, of course. This script requires about five .dlls to be installed.
