Finally I understand the world again!
Hello @TimLau I couldn’t quite figure out from all that was said on this page about Normalize (Two pass) and also from what you write to me.
Now I know why: there seems to be a bug in the effect.
If I have already applied this filter and change the volume by Compressor EQ or whatever, then Normalize seems to go haywire. It makes some values that never seemed logical to me. Of course I have done analysis, but still totally illogical behavior. It doesn’t raise or lower the volume, as would be expected.
But:
But if I Normalize “Remove selected Filter” and then re-apply it, it does exactly what it is supposed to do: It then works correctly.
My Shotcut version is ARCH-22.01.30 on Linux.
It is too early to make a bug report, I need to investigate the phenomenon more.
Yes, the error occurs again and again. Also with shotcut-linux-x86_64-220306.AppImage.
Nromalize works properly only if it is applied last (“Add a Filter”). It does not matter where it is placed. “Move filter down” does not bring any improvement. You have to “Remove Normalize filter” and then select “Add Normalize filter” again. Then it works fine.
I have just reported this bug.
