How to apply crop to a whole film roll?

DT 3.8 on debian 11 (current)

I did a timelapse but my lens was a prime. The camera was on tripod/fixed position. The whole set is in a separate filmroll.

How can I apply the crop from the 1st frame to all the other frames (224)?

Thanks

  • crop the first image
  • copy crop via shift+ctrl+c from the first image
  • select all images
  • paste with ctrl+v

Crop the first image. Go back to the light table, select that image, under history stack, press selective copy. Select only the crop module. Select all of the images in light table, ensure mode is set to ‘append’ not ‘overwrite’, press selective paste, and select the crop module. That will apply the crop to all selected images.

I knew that it was possible, but I couldn’t figure it out.

Thank you
