Thanks for taking the time to read my message.

Here's the deal. I have some .avi files (ripped from DVD I'm assuming) and I want to burn them back to DVD using TMPGEnc, but the videos' quality has been damaged/lessened and the movie has, what I believe are called "artifacts", in it. They are not so bad that you can't watch the movie, but they are noticeable and obviously annoying.

Also, they are not constant throughout the videos and are usually limited to the bottom-right third of the screen.

Of course, I'd like to get rid of them and I'm wondering if TMPGEnc will do that automatically or through some configuration changes, or if there is another better tool to use, or is it not possible to do so.

Thank You.

Hi,

I'm not aware of any software to remove artifacts from an original. Basically you can only get as good a quality as the original AVI.

The best way to do it is to use AviSynth and one of the many noise removal plugins to frameserve to TMPGEnc. It requires a little research to determine what filter or combination of filters will do the best job, but in general what you need to do is smooth out the picture. The downside to this is that you're pretty much guaranteed to do some damage to other areas of the picture that you may not want to smooth. It's also possible to filter only certain frames of the video this way.

You can find a guide for AviSynth and its official editor (AVSEdit) here:
http://www.afterdawn.com/guides/archive/avisynth_tutorial.cfm

There's a section on noise removal, which is what you need to do, but the filter used for an example (Convolution3D) isn't really the best choice. I've generally found that Deen gives good results with little damage to the good parts of the picture. Unfortunately the best source for learning AviSynth (the AviSynth forum on Doom9) is down right now so you can't pick the brains of the experts there, but between the guide in my link and the AviSynth homepage (http://www.avisynth.org/) there should be enough information to get you started.
