Example

Steps to Reproduce:
1. Create a new project:
   - Set resolution to 720x960.
   - Set framerate to 30fps.
2. Add an image:
   - Use an image with dimensions 720x960.
3. Render the project:
   - Export the video to a file with the default settings (or specify if any settings were changed).
4. Observe the issue:
   - A black border appears around the video in the rendered output.

Additional Test Case:
- Added an image with dimensions 1080x1920:
  - Observed a black border surrounding the image in the rendered output.

Expected Behavior:
- No black borders should appear around the video or the images, as they match or exceed the project’s resolution.

Additional Information:
- The Kdenlive project file and setup are included in the attached archive for reference.

Thank you for reporting. I get a correct result following your steps. See my Kdenlive project attached using your images.

Your project file seems to have a different setup which leads to the strange result. Does my project file match your expectations?
