cce video bitrate problem

[DSLGuy]

hi guys, I have a problem with cce 2.70 sp. Every time i do a 2 pass vbr encoding, the output video bitrate is 9800. I don't set it to that. I use the the video calculator to determine the average and leave the max bitrate to 9000. I use fitcd to generate a resize script. The only setting i change in cce is:

uncheck audio setting.
in picture setting uncheck low in detail setting
quantizer characteristics set it 28 cuz i read on a forum when doing an xvid set it between 27 and 30
block scan oder set it to zigzag

and that's all i use. So I have know clue why its doing that

What are the actual bitrate values you are using in CCE ?

Have you checked the true bitrate with Bitrate Viewer or G-Spot ? CCE might simply be writing 9800 to the header, instead of the actual bitrate.

i used 4857 for th average and the default 2000 for the min and the default 9000 for the max and after it encoded i checked with gspot and it said 9800 for the bitrate. same thing when i opened it in TMPGEnc DVD Author 1.6 it said 9800 for the bitrate. so i don't know

Most programs will report the max bitrate and not the avg bitrate,is the file size bigger than it should be?For 2 hours at 4800 the file size should be around 4.17 gb.

Enable full file scan in Gspot and it should parse the file and determine the average bitrate. Even so, it's often not right. VirtualDub is better at it.

[DSLGuy]

the reason why i was getting 9800 in gspot because i was using a older version of it because once i update it... showed the right bitrate of 4857. but that doesn't explain why TMPGEnc DVD Author 1.6 saying its 9800 when i go to author it i get warning about it won't be standard dvd but after i author it and burn it... it plays fine in my 5 year old dvd player lol... i jut wanna know why TMPGEnc DVD Author 1.6 is doing that

[jagabo]

There is a header in MPEG files that gives some idea what the bitrate is. With VBR files that value is usually the highest bitrate. Or just some arbitrary number. That's what you are seeing.

Yep, you have the "For DVD" box checked at the top of the main CCE screen. With that default setting CCE always sticks that 9800 figure in as the max bitrate. It means nothing and you can safely ignore the TDA warning.

If for some reason you might want to get rid of that figure, you can open the M2V in ReStream and change the 9800 to anything you like. It'll still mean nothing, but will get rid of the silly TDA warning.

Or, in CCE you can uncheck the "For DVD" box and then you'll get a figure for the max bitrate you set, 9000 in your case.

quantizer characteristics set it 28 cuz i read on a forum when doing an xvid set it between 27 and 30

That'll be an interesting looking XviD with an average quant of 28, not unlike a cubist painting. A 28 setting in CCE will produce a decent quality M2V.

That's an optimistic view,
I think the only way to describe quant 28 as, is: ugly

He's not talking about quant settings though,
but of the bit allocation per complexity slider.
If I recall, the 27-30 range is off a doom9 guide.

OK, thanks 45tripp. But if it means something different from what I thought for XviD, doesn't it mean what I (and he) thought for CCE - a Constant Quant encode with the Quant set for 28?

[Delta2]

Quant Characteristic determines if CCE gives priority to image details, or evenly colored areas.

The lower the value, the more priority will be given to details, which could result in pixelization or banding in other areas. A high value will result in good looking evenly colored areas, but could result in edge artifacts.

I leave that choice to users, it all depends in people eyes

Now it all comes back. Thanks Delta2. I had set mine to zero so long ago that I had forgotten what it was called. Nothing to do with constant quant encodes at all. It's I who was confused.
