Description Veps 2022-11-03 22:24:24 UTC 
SUMMARY
Adding two (or more) "Alpha Shape" effects to a clip will overwrite each other so just the last effect effects the clip.

STEPS TO REPRODUCE
1. Stack two videos on the timeline
2. Blur top clip for example
3. Add two "Alpha Shape" effects to the top one

OBSERVED RESULT
Only last one gets applied.

EXPECTED RESULT
Both should be effect the video, otherwise there is not reason for an effects stack (adding multple/same effects).

SOFTWARE/OS VERSIONS
Windows: 7

Thank you for reporting. I cannot confirm the issue. Following your steps.

Both Alpha Shape effects appear in the effect stack. Using Kdenlive 24.12.0
Please try with the current Kdenlive version 24.12.0 to see if the issue still exists.
BTW: Kdenlive 24.12 runs on Win10 and higher only.
