Question Divx 5 vs Divx 3

Is it normal for encoding with divx 5 to take longer than when encoding with divx 3. (Using GKnot)

Reason why, i encoded a movie 114 minutes long for 2 cd's and it took about 3 hours and 37 minutes (using divx3), than i encoded a show 119 minutes long for 2 cd's with the same resolution (using divx5.02 with the pro settings) and it took 4 hours and 47 minutes.


Also, does it make a difference in encoding speed if i set the processing level for virtualdub from "normal" to "higher" or "even higher"

Thanks, Robert

Divx 5 is more resource intensive than divx 3.11 alpha.

---I think it would speed up encoding, however your system may become unstable.

NO divx5 is not supposed to take longer!!

you simply should NOT compare different material

each and every film/dvd is different thus do not compare the time two different titles take, but use the same material for speed comparison or take it for granted, that A took longer than B

different filter/resizer may be an additional factor
or the use of for example psychovisual enhancement (crap anyway imho) may slow divx5 down.

Enabling B-Frames and GMC does slowdown encoding a bit. And Q-pel slows the encoding alot.

No, this setting won't speedup encoding by more than 1-2% unless you got some other high priority CPU intensive task running.

Well you guys were right, i did a 6 minute video clip and it took 13:32 with divx 5 (without psycho. vis. enh. and quart. pix.) and 14:47 with divx 3 so divx 5 is actually faster.

But the strange thing is that the compressibilty check is alot faster in divx 3 than it is in divx5.

Also it seems as if divx3 has become slower ever since i installed divx 5 and replaced the decomb.dll file with the newer version.


Thanks, Robert
