Aspect ratio default?

[Lalico 1]

Hello everyone, first of all, I want to say that I love this program so much that I bought Premiere... I would like to know if there's a way to set the "aspect ratio" adjustment to a default value of my choice. Having to change it for every video is tedious, and if I don't, it doesn't make full use of my screen. Thank you very much.

It would also be cool if a video area could be defined i.e. like 2.35:1 and then an aspect ratio applied within this area.

Then IMAX movies would play within the defined area only for 2.35:1 screen users. I think Potplayer can do this.

This would avoid the need for aspect ratio detection tools.

This can also be done with a custom 2.35:1 resolution, but way easier if it can be defined.

Are you wanting to crop or stretch the frame?

I would never use such a feature.  Most film lovers would probably not want to stretch or crop the original format.  I would guess that if you explained to your group friends who would be watching, that you want to crop or stretch and squash the movie / TV show, that they would prefer you did not do so.  This desire to fill the screen is limited to very few individuals who do not seem to notice that actors look like alien creatures or that entire parts of the film are being cropped out and faces are cut off during the movie.  If I was a guest, I would thank the host and just walk out.  I have better things to do with my time then to watch a program that is not in the original aspect ratio.

Neither.

If a 2.35:1 aspect ratio movie is playing on a 16:9 projector & 2.35:1 screen with the lens zoomed in to fill the screen width then define a 2.35:1 video area within the player so when a 16x9 scene appears the 2,35:1 height is maintained.

It would be a virtual resolution and is simply a constant height constant.

This can be also done with a custom 2.35:1 resolution or a crude solution is just turn cropping on the projector for imax but the top and bottom are then cropped.

@generiqsomething like this I believe.

Not possible. If your display is 16:9 you'd either have to stretch or crop the frame to fit the screen. Using --panscan=1.0 will adjust the frame to fit the screen dimensions while preserving the aspect. It will crop the frame as needed when in full screen. So at 2.35:1 the hight will be preserved and the width cropped. And 4:3 will be the opposite. This of course will be dependant on if padding (black bars) are encoded into the frame. Then the calculation will be affected. Other than that, there is zoom or fill. Or even --video-aspect-override, which will also change the aspect (stretching or squashing). Black bars again affecting the output. To achieve what you want would require a complex script that could analyze the image for padding, correctly calculate their removal and then probably apply panscan. There are scripts that can remove padding from mkv files but I'm not sure about other containers. And then that would depend on the containers having the correct frame dimensions of the video. Then there is also what would happen to other videos of different dimensions?

A custom 2.35:1 resolution is probably the easiest option then or cropping for the few movies with varying aspect ratios.

The 4K galaxy quest release fixes this problem with 3 different aspect ratios but all within the 2.35:1 framing. Looks odd on 16x9 displays though.

@Lalicosorry to hijack your thread.

This is different. That script is written to adjust the changing aspects throughout the video based on when the changes occur. You would need a data file that it reads to determine those times. And I believe that Dynamic fit, does that

Yeah probably not worth mucking round for a few movies.

Sounds like the padding needs to be corrected.

This would require --video-aspect-override, resulting in the change of the frame dimension (stretching or squashing) 

Or do you simply mean you want your choice to persist for every video? Like an option at the player level like with subtitles

Looks like panscan is already implemented. I've never tried those options before now.

This script might do what I’m explaining.

You want the dynamic options.

Put it in the scripts folder

[Mahinepua 58]

Sounds like dynamic cover is the setting to try.

I’ll try the latest autocrop2 script also.

Not really much of an issue, can’t be bothered firing up the projector most of the time anyway. First world problem lol.

Mine is better than autocrop 

[Mahinepua 58]

I'm sure it is.

Do I need to set a custom resolution of 3840 x 1634 to make dynamic cover work with a 2.35:1 screen?

I think the autocrop script can do this without changing resolution by setting the 'canvas/screen format' instead. This is what I was referring to in my post above by limiting the vertical video height to an aspect of 2.35:1 on a 16x9 screen then zooming out when a 16x9 frame is detected to fit the reduced height. 

Of course it will need to detect black bars to do this as 4k 2.35:1 movies are 16x9 encoded.

. Cinemascope canvas:

• Set screen format (screen_ratio). e.g. 2.4 or 2.35
• Set the desired zoom option (zoom_min_ratio)

Esto requeriría --video-aspect-override, lo que provocaría el cambio de la dimensión del marco (estiramiento o aplastamiento). 

¿O simplemente quieres decir que quieres que tu elección se mantenga en todos los videos? Como una opción en el nivel del reproductor, como con los subtítulos.

Exactly, that's what I want—an option for the selection to apply to all videos.

The dynamic crop feature aims to address all cases where the regular "Auto" fit mode would lead to have black bars at both top-bottom and left-right, depending on the current video output area. It works dynamically and follows resizing of the app in windowed mode.
In full-screen mode, it's the same: It eliminates black bars, so you have them either at top-bottom or left-right - but not both. The resolution of the screen is the reference for this, as it is taken as the output area of your display. If your display resolution is not representing the desired output area, then yes - you need to change it.

The autocrop script has various modes of operation, but by default it aims to "detect" the aspect ratio of the content video and then locks in to it. You can also define this up-front (or define a number of possible ratios from which it should try to choose one.
On the way to detect this, it can switch around a number of times until "it is sure" about it. You can also configure it to keep switching dynamically, but this is always delayed (until "it is sure") and the switching can be quite annoying.

The dynamic crop feature in the Emby Windows app works differently: 

• It is configuration-free
• It doesn't try to lock-in to a certain aspect ratio and always adapts dynamically
• It dynamically adapts to the current output window size
• Adaption is happening INSTANTLY, it doesn't have any delay, waiting "to be sure"
  This is made possible by additional image analysis and plausibility checks

When you want to compare, try a movie with lots of ratio changes (e.g. 'Oppenheimer')
