I am cropping a video sequence by checking the "crop" box and taking off, say, 200 pixels on both sides. Unfortunately, the resulting video is stretched to accommodate the initial aspect ratio.

How do I avoid this stretching? I just need to crop the video and then "Drop-over" another image or video.

  • $\begingroup$ Did you use Image Offset as well? It might change your Images size, so that you'd have to scale it again, but prevent the stretching. $\endgroup$

  • $\begingroup$ @Samoth I am using the X/Y offset change for the video to move it to the corner, but want the background image fullscreen. $\endgroup$

I use the VSE transform addon when you have added your strip press T and it'll be scaled with the correct aspect ratio, then G, R, S grab rotate scale the strip. see the docs for more options

  • $\begingroup$ How to install the addon? The readme file does not seem to specify. $\endgroup$

    $\begingroup$ like any other... download the py, in user pref/addon tab click install from file and select that file (VSE_Transform_Tool.py) then click on the checkbox to activate. Save user pref to make it permanent $\endgroup$ Commented Mar 13, 2016 at 14:48
  1. Add a Transform Effect strip
  2. Set the Blend Mode to Alpha Over
  3. Use the Position slider to control the right hand cropping
  4. Tick Image Offset under Strip Input
  5. Use X to control the left hand cropping

Similarly for the Y axis
