Description Roxane 2021-10-04 14:41:18 UTC

SUMMARY
The opacity slider in composite on windows doesn't seem to work. I tried with multiple wipes. If the value is 1% to 100%, it's as if it were 100%, 0% is still 0%.

STEPS TO REPRODUCE
1. add composite transition between 2 clips
2. change opacity value to any value that's not 100% (or 0%)

OBSERVED RESULT
The top clip stays fully visible until it disappears at 0%.

EXPECTED RESULT
the 2 clips should 'mix' according to the chosen wipe

A remaining comma/point decimal issue?
Does "affine" transition work properly or is it the same for any type?

Comment 2 Roxane 2021-10-07 09:29:33 UTC

I don't have affine, not ure if it's normal or not. But composite & transform's opacity works fine
