View Full Version : A good deblocking filter for DivX -> MPEG-1/2 ?

Hello,

does anyone know any decent deblocking filters for DivX to MPEG-1/2 conversion? I've heard that SmartSmoothHiq is a good one but the Avisynth version is rather slow compared to the VirtualDub one. I've got some older DivX compressed files that need to be converted to VCDs or SVCDs, hence the question. BTW, does FFDShow decode the clip or is it the lousy DivX5 decoder if I use Avisynth to frameserve?

I'm open to any suggestions, I know you guys have _the_ knowledge:)

AVIsource will use the original DivX5 decoder, and DirectShowSource will use ffdshow.

Hi,

You really need to to deblocking and deringing during the decode and not as an auxillary process. This is because you need parameters which are internal to the decoder to switch on/off and effect the level of postprocessing within a block.

If you need postprocessing then use one of the filters with it.

@hakko: Thanks, I probably wouldn't have figured that out myself..

@dattrax: The idea to use ffdshow is just to ease the filtering process as the quality of the decoder and especially the postprocessing is much better than the original DivX5 one. I'm not sure if it works like this, but I'd suppose that it will, using DirectShowSource as hakko said.
