Created attachment 186898 [details] Showing black where alpha channel and wave are in different phases SUMMARY Wave effect when applied to image or video with alpha channel, only affects the color channels and leaves the alpha channel in place. STEPS TO REPRODUCE 1. Import two images, one with alpha channel information 2. Place a solid image on V1, Alpha image on V2 3. Add Wave filter on V2 OBSERVED RESULT Wave filter ignores the alpha channel information, only applying to color information EXPECTED RESULT Alpha channel moves with the color information, not leaving black areas around edges close to borders of alpha mask SOFTWARE/OS VERSIONS macOS: Ventura 13.7.5 ADDITIONAL INFORMATION Would be nice for Wave Effect to have separate controls for wavelength and amplitude
I can confirm the behavior of the Wave effect. The areas "left" by creating the wave is shown as black not as transparent
