Summary0002816: Composite transition behaviour counterintuitive with 3 tracks
DescriptionHi,
The behaviour of the Composite transition with 3 tracks is rather surprising as compared to other common applications. I couldn't find any documentation to determine if it's a bug or intended to work this way.
Basically, if your top track has a 100% opacity but is above to other tracks with a non 100% opacity Composite transition between them, you will see the lowest one mixed with the top one (the middle one being absent). What I would expect would be to see only the top one.
Steps To Reproduce-Create a new projcet
-Add 3 clips to the project
-Put One clip on each video track, all starting at 00:00
-Add a composite transition between the 1st (top) and 2nd track with default settings ("over" and 100% opacity). Extend the length of the transition to cover the whole lenght of the clip
-you can see that only the top clip is visible in the result
-Add a composite transition between the 2nd and 3rd track with default settings ("over" and 100% opacity). Extend the length of the transition to cover the whole lenght of the clip
-you can see that still only the top clip is visible in the result
-Set the opacity of the lowest transistion to 75%.
-You can see in the result that the top clip appears with an opacity of 75%, the bottom clip with an opacity of 25%, while the middle one is absent.
Additional InformationPlease tell me if you want me to add .kdenlive file and screenshots.

The new Affine transition provides with the expected behaviour.
So this bug could be cloded.
