I know of four options to fade out a strip in Blender VSE: 1) Cross effect strip to black color strip. 2) Gamma cross effect strip to black color strip. 3) Animate opacity over black color strip (or over nothing). 4) Animate color multiply over black color strip (or over nothing).
Is there any difference in result between these methods? Apart from the ability to fine tune the curve of the transition when keyframes are used (in the case of opacity and multiply)? Does the gamma correction make any difference when fading just to black? Any of them looks "better" (smoother, better quality) then the other?
