Summary

0001782: Adding pan & zoom effect to a clip turns it completely black

Description

In some cases adding the pan & zoom effect to a clip makes it turn completely black even though the effect is using its default values. The problem is related to the length of the clip, specifically, if a long clip is trimmed to a shorter length.

Playing the project in melt gives the same black output, so I think it could be an MLT problem.

I am using most recent kdenlive and MLT as of this morning, but I have seen this in previous versions too.

Steps To Reproduce

- Open the attached black-pan-zoom.kdenlive project. The project has a single color clip with pan & zoom effect.
- Play the project and note the image is completely black.
- Examine settings for pan & zoom effect in the clip and note they are default values, so the clip shouldn't have been affected at all by the effect.
- Disable pan & zoom in the clip and play the project. Note the image is no longer black.
- Re-enable the pan & zoom effect in the clip and play project. Note the image is black again.
