I have two videos, one is 1920x1080 and the other is 640x480. I would like to scale the 640x480 one even smaller and overlay it in the corner of the larger one.
How can I do this in the VSE?
For preserving the aspect ratio and the original size of your SD Overlay strip you might need to check
Image Offset in the
Strip Input properties as well as your SD Overlay strip is not the same aspect ratio as your FDH Base Video (and as your project
Dimensions in a
Properties View should be).
With the SD strip selected Add an
Effect Strip -
Transform with an
Blend in the
Edit Strip properties. And finally transform its
Scale (for preserving your aspect ratio you should check
Uniform Scale) under the
Effect Strip properties.
Instead of changing the
Percent (as per default) you can change the
Translation Unit to
Pixels in the same
Effect Strip poperties if needed.
There is a great Tutorial of that on YouTube from Mikeycal Meyers.
