insanely high bitrate yet low qua

[Daedalus01]

Hi

wat im doing is ripping scenes from different movies. These scenes are fight scenes so involve alot of movement.

My problem is that since these scenes last 10min MAX, i dont really care abt file size so want to max out the Divx quality. I use gordian knot to encode, but no matter which bitrate i choose (1500-10000) the final video always turns out blocky when there is lots of movement (e.g Kiss of the Dragon when he's fighting all those karate guys)

how do i improve quality using Divx? i know i can use uncompressed but the filesize is 2 big

thanks

GK couldn't open the log file it seems, the encoding wasn't done properly, as you can see.So obviously, it's going to look horrible ;)
If you redo it, do you get the same error?
Bitrate: 6144 k(=1000)Bits/s Maybe it's too high? :confused: though DivX 5 can go up to 10000kb/s, or so I read, (only DivX ; ) is limited to <6000) .

And on another note, if it's only high motion, you should give a shot to XviD, it's better equipped for it IMO :)
Though you would need to update your GK to make use of the latest XviD,or even DivX 5.1.1,or anything that's remotely modern for that matter, because your version is pretty outdated(understatement, it's prehistoric :D).

FPS: 29.970

Nor can I find any indication that you IVTC'd down to 23.976fps. Unless you Force Film or IVTC, it's always going to look like crap, no matter how high the resolution, and no matter how high the bitrate.

Did you have a close look at the vobs to make sure the blockiness isn't in them also? If it's in the source, then the .avi won't look any better.

[piscator]

A few other remarks.
1) I see you used quite an old version of GKnot (0.27.0.13). Current version is 0.28.8. So time to update :-)

2) A bit of a mess between DivX4 tags and DivX5 tags in the logs. I know, just tags. But another reason to update!

3) I assume you also use the NEWEST DivX 5.1.1 codec?

4) A bit rate of 6144k is ridiculously high. As I recall I never had a movie above 2000k for max quality.

If you want to go for max quality and really don't care about file size. I suggest you do a single pass Quality based encode with Quantizer 2 (use GMC and B-frames if you wish, but no PsyVis).

Or a little bit more sophisticated. Do a compressability check. Do a multipass encode and aim at 80% quality. Use GMC, B-frames and PsyVis fast.

And, of course, don't forget to cut the borders and use for resizing Lanczos.

Both methods should give superb quality.

ok with latest gordian knot qua is perfect.

but now there is another prob, i noticed virtualdubmod now encodes at 4-5fps, whereas b4 it was at least 15fps

my cpu is an xp2100

[Daedalus01]

dont worry all fixed. after reformatting fps went up to 27 again

thanks for all replies :)
