[Bug 506195] Re: Rotating a video clip crops the corners

 

Hi everyone.  Bugs with MLT's affine filter (which is what does the
rotation) can not be solved in the OpenShot source code.  There are a
few different bugs, such as cropping corners when rotating that are very
frustrating, but again, not something we can solve.  This should be
reported to the MLT developers.  Thanks.

Title:
  Rotating a video clip crops the corners

Status in OpenShot Video Editor:
  Invalid

Bug description:
  This might be difficult to fix.

  Under Clip Proterties you can add the rotation effect to create a
  rotating image. Example a spinning cube. Now if I wanted to have the
  cube spin/roll across the screen I would add the rotate effect and
  under the layout tab slide it across the screen. Everything works the
  way it should but the corners of the rotating clip are cropped off as
  it rotates as the dementions of the clip don't expand to compensate
  the corners from going past the original boundaries.

  Quick fix: make the cube image with empty space around it in the
  program it was created in (Gimp). this way it will crop of empty space
  but you have a larger file to work with.

  Hard Fix: expand the Clip boundries to compensate the rotate. OR
  rotate the entire clip with the boundries so nothing is cliped.
