AutoGK and Oversize

[BxWrapper]

<post accidently deleted> sorry from lenox

[BxWrapper]

Well, with the same setting, the old trusted GK gave me target bitrate for video 1434 kbps which output final size (including audio) of 1,400.39 MB for 2 CD setting. Offset by only 0.02% :).

[len0x]

first, try 1.25 (1.23 had very borked DVD2AVIdg version)

[BxWrapper]

The oversize still happened for AutoGK ver. 1.25. I still got 3 CDs for 2 CDs setting:

CD1: 697 MB
CD2: 698 MB
CD3: 256 MB

I got this kind problem for all AutoGK version, I just raised it now. It seem related to how AutoGK decided to set the target video rate which was 1696 kbps for 187751 frames. Seems too high.

I confirmed this problem never happened for DVD ripped. Regards.

[len0x]

tell me - is number of frames from AutoGK logs is the same as in GK when you do that manually ?

p.s. also what is the framerate of original source ?

[BxWrapper]

GKnot detected 187735 frames (as opposed to 187751 detected by AutoGK) and 25 FPS. And I confirmed the source was PAL (with very high interlace content, but that's another story). I am using GK ver. 0.28.7.2.

When I included audio 128 kbps, GK gave me predicted target bitrate of 1423 kbps. Actual was 1434 kbps since audio is mp3 vbr.

Regards.

[len0x]

If the source is PAL then how come you made this:


0xC0 - Audio - MP2 / 2ch / 48kHz / DRC / English / Delay: 0ms
0xE0 - Video - MPEG-2 / 720x480 (NTSC) / 16:9


Last line should be:
0xE0 - Video - MPEG-2 / 720x576 (PAL) / 16:9

Also watch out for 16:9 ratio - it means that source is anamorphic!

[BxWrapper]

I guess that was my mistake. I should apologise for that. So, this explains all the previous problems since I was using the same template !

I will never know if AutoGK parses all this information to make a decission. I thought stream ID is solely the primary important since DVD2AVIdg makes available other information.

Good help and thank you for time.

With new DVD2AVIdg available I'm planning to change that, but atm its how it is.

[BxWrapper]

@lenox,

I made another test with the corrected info and indeed it was the problem. For 2 CD, I now got a perfect size.

CD1: 698 MB
CD2: 697 MB

I thank you again for this nice piece of software (you must have heard this a lots) but but nonetheless it is going to save my time to transcode captures since they dont' quite deserve a manual treatment.

Regards,
