Summary

0001363: Box blur effect in combination with keyframes generates black frames

Description

When applying the box blur effect to a clip, black frames are generated when a keyframe is set to the blur value 0.

Steps To Reproduce

Add a clip to the project, and add the box blur effect to this clip. Set a keyframe at e.g. the start of the clip with blur value 1. Add another keyframe, say 1 second later, with blur value 0. Render the project and replay the video. You will see that at 1 second into the video, a number of black frames are observed.

Additional Information

When observing the problem, the source for my clip is AVCHD-encoded video (16:9 anamorphic 1440x1080@50i from a Sony HD Camcorder), and I rendered to H.264 (16:9 anamorphic 720x576@50i).
