TMPGEnc: Is noise reduction a good idea?
 

I regularly encode from Divx .avi's using kvcd templates in tmpgenc. Sometimes the divx sources can be a little noisy. Would the noise reduction filter in tmpgenc help with this, or is it there to limit block noise in your output file?

Try using Fluxsmooth. It's much better and far far faster than TMPEG's noise filter :wink:

I think the best approach -- nonsensical as it might at first sound -- is to try to remove as much of the existing noise as possible, then add some back in to low-detail areas if you need it :).

Ohh.. with the Blockbuster filter? or Undot? I've read some of your posts on that, but haven't made any attempt at it yet.

Using Blockbuster.

It's not non-sensical, because the noise you're adding is different from the noise you're removing.

The noise in the source (blocks, ringing, solarization, etc.) is highly correlated to the source (that is, you have the "ringing" - mosquitoes - following the edges, etc).

The blockbuster noise on the other hand is non-correlated, or "random".
