Hello.

I believe cropping is not working. Here is parameters line I used:
-vf "crop=in_w-960:in_h,scale=1920:1080:flags=bicubic,shanacrop=DAR,setsar=1/1"

And the resulted video has cropped left & right bars with "crop" filter, but not cropped top & bottom with "shanacrop" during scaling down to 1080p and changed aspect ratio. So output is squashed. Please see attached screenshots.
Arguments other than "DAR" produce the same result.

P.S. I used to be able to crop 16:10 video to 16:9 with GUI settings in some previous version, but now cropping setting seems to do nothing. And I am also unable to find download for older versions on this site, which is a problem as well.

Thank you for your development.

    You're doing crop ⇒ resize(scale) ⇒ crop. It's not a good work flow. Instead, do all the crops via [right click] > [Set segment/Crop] seeing the result in advance, and then do the resize.

    DAR means the display aspect ratio of the source. In resizing, Aspect: None or Padding (letterbox) is recommended. Don't do cropping there, 'cuz it will yield an unexpected result sometimes.

    DAR means the display aspect ratio of the source.

    Is it? I was pretty sure that it is aspect ratio of ouput (at least in terms of ffmpeg), and it sure did act like that in previous ShanaEncoder versions. Setting output resolution of 1920x1080 and croping = DAR yilded for example 16:9 centered crop of 16:10 video without distortion.
    Even if I now set "shanacrop=16:9" or any other argument, the output is still identical. Does not seem right and very confusing.

    I was using this setting for simple reasons:

    a) it is located in main "Quick settings" menu, so seems like a logical way to do it.

    b) it requires no calculations in case you need centered picture output

    Thank you for pointing to "Set segment/Crop" menu, I was completely overlooking this submenu. It works well as a workaround.
