AGK ignores aspect ratio

[exekutor]

Hi there

i have a little problem with a series DVD. One (and only one) episode of that series is always encodet in 4:3 and thou some details on the left side (not on both sides) are missing.
However, the whole serie ist ar 16:9 and all other episodes are encodet in that ar.
The DVD is at 16:9 ar. I ripped the episodes via DVDDecrypter. The ripped files are also 16:9.
I encode with fixed witdh, but the hight of that specific episode is too high for the right ar.

Has anyone of you an idea, how to get that episode in the correct ar of 16:9 ?

[BigDid]

Hi there and welcome to the forum,

Use AutoGK hidden option (Ctrl+F9) Check "Override input AR" and set the .aspect to 16:9 or original.

Explained in the tutorial/Hidden option/aspect ratio.

Thanks 4 the reply. I forgot i did that already, without any effekt :/

[manono]

That's because AutoGK already sees it as 16:9.
[10.08.2009 05:33:46] Source aspect ratio: 16:9
However, it's not being encoded as 4:3, but 3:2 (1:48:1). Perhaps it's going wrong when scanning for the crop values. Are there places in that particular episode where there's a lot of black on the left (and maybe the right) side? That might explain the parts missing from the left side. You can force a crop of whatever you like in the Hidden Options. If you want nothing cropped, set the Threshold to zero. Read the enclosed tutorial for more options.

And you don't have the "Override Input AR" box checked in the Hidden Options, do you? Since it already sees it as 16:9, checking that box might lead to the results you're getting.

We do not know whether the thread originator got his problem solved or not. If Mr manono's reply was of help, then perhaps some thanks are due, but mostly, I suppose, a general benefit will accrue if we knew how the problem was solved in this particular case.

Regards.
