DivX 5.0 Guide Work

**khp** · 5 Mar 2002, 11:51 PM

Doom9 has beat us to it

Any guide work will depend heavily on which tools are used.

Which tools are u interrested in using ?

I am currently working on some side by side comparisons of divx4.12 and divx5.0 using different settings (B-frames,QPMC and GMC) will post results when done.

kind regards

As promised here is a short comparison of the divx4.12 and 5.0 codec.
I have used 1-pass constant quality (100%), in order to use filesize as an objective measure of codec quality. All the encodings were done without audio.

Divx4.12 filesize 1.48GB (1,590,431,744 bytes)
Divx5.0 Basic 1.47GB (1.580,339,200 bytes)
Divx5.0 Q,G 1.34GB (1,446,283,264 bytes)
Divx5.0 B,Q,G 1.04GB (1,124,216,832 bytes)

B = using B-frames.
Q = using Quarter pel motion compensation.
G = using Global motion compensation

The filesize reduction gained from using B frames is quite impressive, if the quality is indeed unchanged.

Comments are very welcome.

did u do this with the pro version or the basic one?

i noticed that the pro version causes some nice probs, as it only plays well in the new playa and causes some crash too

Finally, DIVX 5 is better than 4.

DIVX 5 still sucks (a bit) because the quality isn't great, lines everywhere! yeh, sure the file size is down but not as good as 3.11alpha!

Yeh, I done some tests too and yeh, DIVX 5 is the next thing to DIVX 3.11alpha.

But it's best to wait till a few more releases are made of DIVX 5.xx due to the bugs being solved.

PEACE AND RESPECT!

All the divx 5 tests were done with the pro version (only one that can do B,Q,G). The 5.0 Basic test was done with both the pro and the standard version and gave identical results.

I have not had any playback problems with any of the test files, using wmp6.4.

**techno** · 6 Mar 2002, 05:02 AM

hmmmmmmmmm wierd, I too use wmp 6.4

But still, the file size is the Issue.

let me say:

I create HIGH quality captured stuff, then edited in MPEG2...

Then to DIVX 3.11alpha fast motion 6000bitrate.

The quality is ACE!

File size = 15MB

But, if I do it DIVX 5, the file size is 25 (better than DIVX 4.xx) but quality is not great, even using 1 pass quality based.

There are lines on the screen, vertical and horizontal and also it plays jerky!

DivX 3.11 is nothing but a cracked version of WMV. I can't stand it when people praise DivXNetworks for 3.11 when they didn't really create it! They DID create 4 and 5, which are awesome from what I've seen. The last guy said he used 3.11 fast motion at 6 mbps - just use the new DivX at 2-pass VBR! There are so many guys out there criticizing DivX 4 becuase it didn't look as good as the stuff they downloaded, but that's only because those guys keep using 1-pass. 1-pass looks like garbage! The only reasond the 3.11 stuff they downloaded looked so good was becuase it was done with SBC in 2-pass. I've been encoding 4.12 is 2-pass and it is much better than 3.11 ever was.

DivX 5 is alot better than the last two generations od the format, it just has a few bugs right now. Don't sweat it - just wait a while for the new releases.

ok ive used Divx 5.0 and here are my thoughts.

i recorded a two part movie into premier 6.0, each half was 10GB and i used premiers batch processings utility and encoded to divx heres what the settings were:

Codec: Divx 5.0 pro 1-pass (non quality based, no extra features)
Resolution: 720x480
Audio: microsoft ADCPM 44Khz
Output files: 450MB each, thats impressive. i couldnt even get Divx4.12 to work.oh yea and the quality was perfect, no lines or anything.

big salute to DivxNetworks!!!

I know that 3.11alpha was cracked (duh).

For me, DIVX 5 is not as good as 3.11alpha because the file size is still a bit big, better than 4 (no doubt about that) but why are there lines on the screen then?

I am just wondering, I am not here to argue or blowup!

Just a freindly question/debate

I am a 3.11 codec loyalist anyway. Long live Nandub!!!

**Enchanter** · 6 Mar 2002, 08:08 PM

By the way, for those of you who installed DivX5 and who already have 3.11 installed, did the codec ask if you would like it to play 3.11 contents?

**techno** · 6 Mar 2002, 08:08 PM

nope, it didn't but plays it anyway!

**Enchanter** · 6 Mar 2002, 08:11 PM

They had better fix that in the later releases or I won't even consider replacing 4.12 for it...

**techno** · 6 Mar 2002, 08:14 PM

hehehehehehehe....

Don't even install it!
