I rendered some video effects that I want to overlay on top of some video footage in the video editor. The video effects are imported as an image sequence.

Turns out the video effects are too transparent. I can duplicate the image sequence and stack them to increase the opacity, but is there a better way? I tried the curve strip modifier but it can only adjust RGB.

Here is a screenshot of my current setup (edited to remove personal info), all the clips are in "Alpha Over" mode.

  • $\begingroup$ Ok that seems to work, thank you. Is it equivalent to the image stacking I was doing before? $\endgroup$

  • $\begingroup$ I don’t know what you mean with equivalent, but I think it is a very similar effect. $\endgroup$

  • $\begingroup$ I guess I'm asking is "mathematically", does changing the multiple/saturation have the same result as stacking images $\endgroup$
