Divx5 settings database

[ChannelK]

A lot of people appear to be asking for exact settings to use, and as everyone knows there are no exact settings for every movie, but, what about this idea.

An online data base of settings people have used for given movies. Then, when someone wants to encode, they look up the movie on the data base and use those settings. The database could include the settings people have used to get a good looking rip, and once a setting is posted, and someone else uses them and can vouch for them, no more can be added for that movie (to reduce potential size). The database could include fields for 1, or 2 cd rips for a particular movie to use in virtual dub in conjuntion with Gknot etc. Im sure this wouldnt be hard to do and include somewhere in the forum.

What do you all think?

First you would have to have two different databases - 1 for ntsc and one for pal. Then you might need one for people who encode only for tv output and one for only computer. Now who gets to set in stone what specs are the best (its all subjective).

My point is that this would be a huge database and a great undertaking to keep it updated. Then it could only be used as a reference since there will be disagreements all the time.

A better idea may be to have a forum section devoted to hard to encode movies or anime.

imho

Ok, so it has a few bugs, it was just an idea. I would think many people already use a system close to this them self, storing various settings profiles and then 'fine tuning' a profile to suit a particluar movie.
But yes i agress that perhaps your forum idea would be better, in any case, a starting point (basic settings that worked)i think would be usefull to the general population, especially those asking for settings only to be dismayed at the answers, isnt this idea what they are after.
Ps. and this is gonna sound stupid, what is imho?

imho=in my honest opinion

It would be nice, but it would be a rather large undertaking. One database for PAL, one for NTSC. People could upload vcf files and .log and .stat files and screenshots. To avoid bandwidth problems, it might be a P2P setup, or a hub on Direct Connect.

It must be a pipe dream, I suppose, for people have raised the issue before and it never got off the ground.

@ midiguy
That was a good one, I was waiting for a picture to load :D

yeah, I like to waste peoples' time.

@ChannelK,

if you want an easy and fast way to get good settings, try doing this:

Use gordianknot as a bitrate calculator, and to determine the compressibility of your movie (so you can get an optimal resolution choice).

then almost always use neutral bicubic resizing (soft bicubic on animation or on very long 1 CD materials, even bilinear for noisy animation but not for live movies).

DivX 5 settings:

disable q pel and GMC (there are some bugs with GMC with the current DivX 5 decoder, should be fixed next version though). and enable b-frames.

now the advanced parameters:

max quant: varies (make it from 8-12, do some test clips that have both high mo and low mo in them... for 2 CD rips you can probably safely go 8-10, it really depends on the material)

RC averaging: half of the total frames of your movie (so if your movie is 500 frames, it should be set at 250)

you can make everything else the defaults..

and no psycho stuff!

also, force film when possible and if not possible IVTC with decomb!

also make sure not to resize with the codec's built-in resize filter. it is shitty.

that should give you near-optimal if not optimal settings.. can't get much closer though.. so be happy :D

and sorry if I went into too much detail here..
