Ran 4 test runs using DVD2SVCD on a DVD music video that is about 7 minutes long.

CCE ran twice as fast as TMPGenc

CCE Q5 = 121,341KB
CCE Q40 = 115,420KB (semi-blocky)
CCE Q80 = 102,885KB (blocky - vcd quality)

TMPG CQ80 = 125,072KB

All settings were same except for Q value for CCE

Max bitrate = 2500
Min bitrate = 300

SVCD

MPEG-2, SVCD, 480 x 480

I am playing around with CCE since it is way faster and time is a premium on a shared family computer! My wife kkeps complaining about encoding time!

After all this experimenting, SVCD's play the smoothest on my player. KVCD's sometimes stutter and lose sync. Might be the GOP I am not sure.


The Doom9 forum is not too helpful, all I get is moderators saying I am not following rules..........

I love KWag, he don't get on people for being chatty

about "KVCD's sometimes stutter and lose sync":
try encrease the audio kb(128 to 160),just a little
some player don't like low audio bitrates.


thanks for the infos telemike!

Hey, CCE"s Q factor has nothing to do with TMpeg"s CQ factor.

Have a look at the CCE"s user"s manual:

"...Q.factor: 1-40, Priority is given to image quality over compression rate.."

Increasing the Q factor u got high compessed files with bad quality image.

really right VILLA21


CCE and Procoders are champions for mpeg2!
for this reason i post this:
http://www.kvcd.net/forum/viewtopic....44e9a6b90e1ab7

cos one of my dreams is "tranpose" the Kwag's templates
to CCE and/or Procoder. but don't know how can i do it.

this could be fantastic!

I am amazed at the speed difference of CCE over TMPGenc. Though I can't control CCE as well as TMPGenc like I can with ToK and CQ.

Yes, it works opposite as in TMPEG. Lower the value, increases the file size and quality. You can use the file prediction method (100%/10%) and it will work with CCE. I tried it the other day, and it produced the correct sample size
File size target is file size target, no matter which way we look at it, even though some (incorrect) statements related to file size prediction by some users at the doom forum insist that Q vs. CQ statements are not the same. It's not the same encoding algorithm, that's for sure, but the outcome after finding correct CQ(TMPEG) or Q(CCE) targeting a constant file size is the same result

The Q range for CCE is 0-300 and the lower the value the less compression. It correlates fairly well to TMPGEnc CQ actually. For example if you use a Q of 40 in CCE you can compare it to, roughly, a CQ of 85 in TMPGEnc by this formula: (300-Q)/3 = CQ. By the way Jorel, in the latest versions CCE you can edit the matrices and save them as presets.
