OK, guys, what should I work on? We don't have any open bugs/issues. I was thinking to work on Guest 2's language preferences stuff. But tell me what y'all want. Think big!

OK, I'm going to work on autocropping improvements and language preferences.

Please explain more. Thank you.
Also it was Guest 2 IIRC that asked for the main window navigation to remain enabled when the crop window is on display. That way you can sample around to see if the selected cropping is good everywhere. Or we could run a pass over the entire stream finding the cropping that catches all the blackness. Is that what you were thinking of, gonca?

I believe one such movie is The Dark Knight Rises.
Some of the movie is shot in a 2.40:1 aspect ratio while other parts are shot in 1.78:1
Different ratios in the same movie.
Would be good if autocropping could scan the video to find the "correct aspect ratio"
In this case 1.78:1 since that fills the screen
You are right, we can do it manually but if we had an automated way it would be easier

Please give link to purchase that disk. Thank you.

I manually scan the entire timeline (dragging the navigation slider) and look for different ratios.
You can see the top and bottom black bars appear and disappear.
It isn't that hard to do, so this is one of those "would be nice" items
Guest 2's language selection would also be useful

@gonca
OK, the movie has parts that require no cropping (no black bars) and parts that require cropping (has top and bottom black bars). What are you expecting an automated cropping function to do with that? Leave everything uncropped or crop everything? Just report on matters?

With auto cropping I would expect it to have zero cropping on the height in this case
Example
Movie has aspect ratios of 3840 x 1600, 3840 x 1800, and 3840 x 1700
Auto cropping would report a cropping value for 3840 x 1800, the largest picture area with actual data, excluding black bars for padding

OK, thank you. Makes sense. I'll have to scan the entire stream to find the maximum cropping that does not crop real content.

Gonna have an Analyze button that runs a scan of the whole stream skipping by GOP. At each GOP start frame the cropping will be calculated and then at the end the smallest crop will be set as you described.

Sounds good.

Gonna need to have Analyze mod4, mod8, and mod 32 buttons, unless you can think of a better UI. And hopefully going by GOP won't miss anything.
I already have the cropping dialog non-modal in my local build. Sensitivity has been increased to 40, which better clobbers near-blacks.

IMHO there is no need for 3 different analysises.
Once DGIndexNV becomes aware of the wider/higher resolution, it can crop to that one, applying the desired MOD.
In future it could output different DGI/AVS for every different resolution part. The need for this is that, apart from IMAX movies, some restored ones have different resolution for the recovered parts, that need different filter treatment. Having the trimmed parts would be way easier for us to work on them.
Why don't you expose that parameter?

Hi Rocky! Bit of time I haven't written you
Perhaps I have wrongly understood and I have pictured you want to run a separate analysis for every mod. Am I wrong?
I meant, a sensitivity slider in the options.
DGDecNV cropping improvement
We have now an autocrop button for each mod that works on the current frame. What buttons would you add and how would they work to support scanning the entire stream and autocropping accordingly?
If the user has to determine sensitivity per source using a slider then the process is not automatic. In any case, I do not see the need for making it configurable.

I would add one more button only for scanning. Useless to scan multiple times just to have the preview of each crop mod.
DGDecNV cropping improvement
C'mon, think it through and answer thoroughly. I have to write actual code. What will be the result of a scan and what will you do with it and when? Can't do a scan and then select one of the existing autocrop buttons, because they are implemented to autocrop the current frame.
