Andrea, I can verify that moving Alpha Slider in ChromakeyHSV seems to have no effect in build with ffmpeg 7.0 . And for me it has no effect with the Feb. Appimage (ffmpeg 6.1) or even June 2020 binary. Will attempt to go back further to check more. On Fri, Apr 12, 2024 at 1:07 AM Andrea paz <[email protected]> wrote:
In CinGG compiled with ffmpeg7 I find "strange" behavior that I do not encounter with appimage (which has ffmpeg6). Using a greenscreen image, as the top track and any media as the background track, we need to apply the ChromaKey HSV plugin. We can see that the "Alpha Offset" slider does not produce any change. It does not work. If we repeat the same test with appimage, the slider works normally.
Can you verify if this is also the case for you or does it depend on me or my system?
I have also tried other plugins that use the alpha channel, and also patchbay overlays, but everything works fine.
