Short description of error
Adding a movie clip to the node editor and linking it to a composite output results in a clip that gets cropped to the center of the original movie clip if the output has a lower resolution than the input.

Exact steps for others to reproduce the error

  1. Add 4k video to the node editor
  2. link a composite output
  3. set output resolution to some low res (Full HD)
  4. render

This SO was my first attempt at figuring out what's wrong. Given this "bug" is unresolved and unreported since years, I suspect it's not a bug. No blender expert here.

Thanks for the report, but it's not a bug. Such scenario acts like "canvas" type of things. This is how it worked historically in Blender and changing this will cause quite some compatibility break. Just set output resolution to the video resolution. alternatively you can use Scale compositor node.
