Can anyone please let me know how I can change the aspect ratio of a video to a custom (not standard) ratio? or make a new project with custom aspect ratio?
I'd like to make videos of specific sizes like 400x400 or even 200x400, but I don't know how to do it in Premiere.
Thank you in advance

Change your sequence settings to "desktop"; this "unlocks" all the settings and you can enter custom values for everything
Or , from a given sequence , you can resize it when you export in AME -
thanks for your reply. I am a beginner and not sure how to change the sequence settings to "desktop". I couldn't find any setting with "desktop" option in sequence settings. Can you please let me know how to do it?
Also when you say "you can enter custom values for everything" what exactly you mean that is related to aspect ratio? I can change position and scale width/height, but again I couldn't find any setting for aspect ration except the standard options in sequence settings.
thanks -
If you have videos already that you are importing, they already have a certain aspect ratio. Then you would probably use the second option of resizing in Adobe Media Encoder when you export. There is a setting for pixel aspect ratio (PAR). If you use 1:1 , it will use "square pixels". So the resized dimensions will determine the display aspect ratio (DAR) . So it depends on which Aspect Ratio you are specifically referring to. I suspect you mean square pixels, for something like 400x400
If you are doing it the other way, you can think of a sequence as the "canvas" of a painting. So you can resize the various videos and assets to the sequence, but they might get distorted if they are already different aspect ratios (e.g. circles become ovals). Or you might need letterboxing or pillarboxing to preserve the aspect ratio (black borders), or crop out an area. For example , if you had a 400x400 sequence, 1:1 square pixels, it would be a "square". If you droped a 16:9 video (e.g. 1920x1080) onto that, it would be too wide, because the DAR is 16:9. So you would have to either distort the image (squish it so everything is skinny), or crop off the sides
To set a custom sequence, create a new sequence , hit the custom tab, and under editing mode select "desktop" -
Thank you very much, I found it. Although, in the latest version, there is no custom tab. It is "setting" and in the editing mode, there is no desktop option. It is "custom".
Now, there is another issue:
Suppose that you have a HD video captured by your camera mounted on tripod inside your room looking outside through a square window. So in the video there is a square window that is opened and the camera is capturing whatever is outside of the window. Now I want to crop/resize the HD video so that I can have just the square window in the new video. I can crop the HD video, but when I adjust the crop size it is in percentage (%) so I have no idea what is the actual size of the cropped area. So there is a big black not-symmetric area around the cropped area. If I know the exact size of the cropped area I can change the frame size to the exact size of the cropped area. so do you know how I can find the exact size of the cropped area in mm in premiere (and not in %)?
Thank you -
If I'm understanding what you're describing correctly, it's probably easier to do those manipulations in AME when exporting. You can drag the window to the region of interest and it will give you the pixel values in width, height . You can use custom settings to render out
If all you are doing is cropping video, there are many other programs that can do this faster, easier. PP is overkill for just cropping -
so no way to do this is Premiere?

This is an annoying long time shortcoming of premiere pro. Heck it would take a junior engineer at most a day to put the actual size in parentheses behind the percentages.Originally Posted by N3SH0m

Not in premiere, only by %
The proper way to do this is in AME, because that gives you the flexibility to use the entire video for other purposes. If you set a sequence setting for 400x400 (or some little window), this means all your projects based on this will be limited to that window. Setting the sequence to the full video allows you reuse the project with edits , saving you lots of work.
See post #3 . It's not show in the screenshot, but if you mouse over the window, it will show you the pixel width, height dimensions

So you could use AME to read off the pixel values, apply them to the sequence, but then you would have to reposition the main video in the sequence to fit the little "window". It's not a smart way of doing it. You might as well use AME in the first place and have many more options for this project and future projects -
I got it. thank you very much for your help.

If all you are doing is cropping, you don't even have to use PP - you can load video directly into AME to do those manipulations
(and there are bunch of other free tool that can crop easily as well) -
yes, that's right. I am not just cropping. Thanks again.
