ASP postprocessing shoot-out

[temporance]

Has anyone ever tried comparing deblocking/deringing of the various ASP decoders? I would be interested to read more if there have been any independent experiments.

Yes, I did :search: but could only find encoder comparisons.

This post today by videomixer9 seems to be the most thorough test there is:

I'm quite surprised that no-one else has spent any time looking at this.

Hopefully when I have some time, I'll make some tests of my own and post the results here.

This might not be the answer you're looking for in this topic, but in my opinion no postprocessing is the best postprocessing. :D Obviously this depends on the personal taste, others may have different opinion, but i simply hate the smoothness what postfiltering causes, while i can tolerate some blocking. Postfiltering is only beneficial at low bitrates, where there are many better choices than the ASP codecs anyway.

Postprocessing=NULL is a perfectly valid option and should be one of the candidates in any comparison. Personally I don't believe it's the optimal choice: a well tuned PP algorithm should only remove block edges: there is no reason why a side effect should be over-smoothed images.

Can I ask which decoders (and versions) you've experienced that lead you to this opinion, Tommy?

Xvid, ffdshow with mplayer's and Nic's method, an older beta version of divx 6, and years ago divx 3.11. As i said, this is a personal preference, i just never liked the looks of postfiltered videos, the disapperance of the subtle details has always bothered me (and i experienced this with all of them), especially in near-transparent encodings, where artifacts are rarely an issue anyway.

I like SPP deblocking in ffdshow at level2 and 85% strength
