Description Mario Becroft 2018-01-01 08:17:31 UTC

Effect Groups cannot be used in Bin effects. When editing Bin effects for a Project Bin clip, a Group can be created containing one effect, but dragging other effects into the group does nothing.

Furthermore, if a Custom effect is created that contains an Effect Group, this Custom effect cannot be added to Bin effects.

Steps to reproduce problem A:

1. Add at least one clip to the Project Bin
2. Drag any two effects from the Effects pane into the Bin effects
3. Create an Effect Group by choosing Create Group from the topmost effect's hamburger menu
4. Drag the 2nd effect into the newly create Group.

Expected result:

The 2nd effect is moved into the Group with the 1st effect.

Actual result:

Nothing happens. Furthermore, after clicking away from the Bin clip then back to it, the Group has vanished and the 1st effect remains, ungrouped.

Steps to reproduce problem B:

1. Add at least one clip to the Project Bin
2. Drag a clip into a Video timeline track
3. Drag any two effects from the Effects pane into the newly created timeline clip's effects
4. Create an Effect Group containing both effects
5. In the Effect Group hamburger menu, choose Save Effect
6. Select a clip in the Project bin
7. Drag the newly-saved Custom effect from the Effects pane to the Bin effects pane.

Expected result:

Custom effect is added to the Bin effects.

Actual result:

Nothing happens.

Versions:

Kdenlive 17.12.0

MLT 6.4.1

KDE Frameworks 5.40.0

Qt 5.9.3

Secondary issues:

A way around the inability to use a saved Custom effect with a group as a Bin effect would be to set up the required effects on a single clip, then Copy that bin clip and Paste Effects to another Bin clip. But there is apparently no facility to copy and paste Bin effects whatsoever.

I've also noticed a minor, probably unrelated issue: Right click on a Custom Effect containing a Group and choosing Delete effect does nothing. Custom Effects consisting of groups cannot be deleted from the kdenlive GUI. They can be deleted by the rm command on the relevant Custom Effect file in the filesystem.

Clarification--it is possible to copy Bin effects between Bin clips, by dragging an effect from the Bin effects panel onto a clip in the Project Bin panel. But again, because effects cannot be grouped, this has to be done one effect at a time. I can still find no way to simply copy all bin effects from one clip to another, which is my main purpose here--set up one set of bin effects for a given camera and apply it to all the files from that camera.

I change it to Refactoring Version. And change it to wishlist.

We close this bug as we track it in Gitlab under https://invent.kde.org/kde/kdenlive/issues/4 for re-implementation.
