Created attachment 152359 [details] Effect panel SUMMARY I'm trying the Audio Spectrum Filter effect for the first time. The effect works as expected. But when I tried to apply different Angles to the keyframes the values weren't saved to the keyframes, e.i. all keyframes have the same values. That happens to other parameters, too. STEPS TO REPRODUCE 1. Enable the audio mixer. 2. Apply Audio Spectrum Filter to the master control. 3. Add some keyframes into the effect and change the value of the Angle in different keyframes, see attachment. OBSERVED RESULT The angle of the spectrum display is changed respectively, but for the entire timeline. EXPECTED RESULT The angle of the spectrum display should change from one keyframe to the other SOFTWARE/OS VERSIONS Windows: 10
Thanks for your report! I can confirm this behaviour. However it seems it is wrong that the UI shows the keyframe widget at all, since the audio spectrum filter does not support keyframes yet. BUT I started to implement this upstream in MLT with https://github.com/mltframework/mlt/pull/827 We can make this available in Kdenlive as soon as we depend on MLT >= 7.10
I just quickly checked on the comment on your git merge request: > jlskuz commented 26 days ago > this affects audiolevelgraph, audiosprectrum and audiowaveform Will this effect the possibility for opacity as well? I was about to open a bug report but just realized from the supplied screenshot here that the "Audio Spectrum Filter" doesn't show "opacity" while the "Audio Level Visualization Filter" (that's what meant by audiolevelgraph?) actually does -- seems crooked to me! However I would very much appreciate if this would also support opacity-levels though... :)
