«Size Mode: Fit» + «Preview Scaling»

I have a feeling that this bug must have been spotted by someone else before. But I didn’t find any mention of it. So sorry if it’s a duplicate.

What is your operating system? Windows 10
What is your Shotcut version? 23.06.14 (also in 22.12.21)

Can you repeat the problem? If so, what are the steps?


  • Project size: 1920x1080

  • Preview Scaling: OFF

  • Add a clip smaller than the project in the timeline. In my case, a 600x646 JPG image.

  • Add a Size, Position & Rotate filter:
    The clip is resized to fit the height of the screen.

  • Change Size Mode to Fit:
    The clip is displayed in its real size…

  • Change Preview Scaling to 360p:
    In the preview, the clip fits the height of the screen again.
    It will look as expected after exporting though.
