Undersizing using 2.70.2.0

[jdobbs]

You have to be careful in comparing values.... Q in CCE is not just "Quantization" -- it is one of those mysterious CCE values that means "Quality" and includes quant but not just quant. For example, if you do one pass encoding in CCE and set the Q equal to 10 you might get quants that are 3.

No worries. If the above quote is anything to go by I wouldn't have been able to understand it anyways.

Have Cinemacraft responded to your support request yet? I would have expected them to have done by now, especially with the money they charge for the product.

Yes they answered, but only are concerned in bugs and they don't consider this a bug.

They also mention saturation and said the encoding engine was improved and totally different of that used in 2.66/2.67 versions of CCE.

They claimed that CCE 2.70.2.4 has an inmpoved engine and thus results can't be comapred on bit level to previous versions.

As far as I subjectively see the quality of 2.70.2.4 I have no complaints at all.

It's still a superior encoder in my opninion but I also have to do more testing on HC 0.16 encoder.

But as long as HC is beta I just do not wanna make my backup's with it, because it is not impossible that HC has bugs and my backups will also have them.

I try it as I really deeply respect someone to be capable of building such a complex piece of software.

No I mean Q in bitrate viewer.

And I don't ever use OPV or something like that.

Still I wonder the max bitrate of 1219 Kbit/sec over a 120 kbits source.

That is really of interest to me.

[jdobbs]

DVD-RB assigns MAX_BIRATES of 1219 Kbits/sec after prepare !!!!!!

This is far too high and now I wonder what CAN happen in other cases....

JDOBBS , you told me the source was inspected as GOP-level and that bitrate determines the MAX_BITRATE for that segment.

But 120 Kbits source results DVD-RB in believing the max is 1219 Kbits/sec for a segment !! Apfraats, please stop talking all this nonsense! The maximum bitrate setting also has other considerations that will be allowed within DVD-RB in order to give VBR some room to work.

You are way over your head here... but unfortunately those who don't understand these things are reading your posts and don't know the difference.

I ask again. Please stop this obsessive nonsense. I am familiar with the knowledge levels of people like Hank315 and DragonGodz... and to argue with them about MPEG is really, really a futile effort.

I remember only a few days ago that you said "JDOBBS is wrong, there is no such thing as saturation". Now here you are talking as if you are the "Lord of Knowledge" on the saturation issue.

I understand that you are trying to learn from these posts and test the outcomes... and that's fine, but arguing with people isn't helping you learn.

[apfraats]

My only goal is to learn by testing and trying.

I admit I haven't youre level of knowledge, I wish I had.:)

But some statements are done and I just want to test them and most of the time you use extreme situations to get things clear.

I also told in my previous post, if you read carefully, that it could have something to do with a minimum maximum bitrate you use for some reason.

I just ask to try to understand.

So if you simply react to my post saying:

Apfraats, DVD-RB uses a minimum setting for MAX_BITRATE to give room for VBR encodings and that level is xxxxx Kbits.sec

has more use then throwing peronal remarks at me.

I'm just learning, trying and testing, and yes, making mistakes is part of that proces....

[jdobbs]

Maybe it's the language barrier, Apfraats, but believe me -- your remarks are very personal and often offensive.

No harm, no foul. Let's move on.

[apfraats]

That's what I don't want to be, believe me.

It's indeed my limited vocabulair and I know I have a way of making short statements but I don't mean any personal issues by that.

I even try to convince as many SHRINKERS as I know to use DVD-RB-PRO because of it's superiour quality, I never complain(ed) about that.

My starting level here , a long time ago, was even the question 'SHRINK or DVD-RB ?'.

So I have learned a great deal........:)

Indeed let's move on.....
