<div dir="ltr"><div class="gmail_default" style="font-size:small">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.<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Apr 12, 2024 at 1:07 AM Andrea paz <<a href="mailto:gamberucci.andrea@gmail.com">gamberucci.andrea@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">In CinGG compiled with ffmpeg7 I find "strange" behavior that I do not<br>

Using a greenscreen image, as the top track and any<br>
media as the background track, we need to apply the ChromaKey HSV<br>
plugin. We can see that the "Alpha Offset" slider does not produce<br>
any change. It does not work.<br>
If we repeat the same test with appimage, the slider works normally.<br>
<br>
Can you verify if this is also the case for you or does it depend on<br>
me or my system?<br>
<br>
I have also tried other plugins that use the alpha channel, and also<br>
patchbay overlays, but everything works fine.<br>
