Summary0002956: obscure effect does not work when keyframes are used
DescriptionThe obscure effect works if you add the effect and move to the first frame of the clip and adjust the box. see obscure.png attached

But if you move off the first frame and double click to add a keyframe the effect stops working. obscure_bug1.png and obscure_bug2.png

As you can see in the screenshots the interface to the keyframes is missing in this effect - it does not look like keyframes in the other keyframeable effects. For example there is no add keyframe icon or jump to next keyframe widget.
 I dunno if the two issues are related.

Keyframing in this effect is pretty important so we can track around where in the shot we need to obscure.

Still have this issue on kdenlive 0.9.5+git20130202.95231df4-0ubuntu0~sunab~precise1.

The rectangle migrates with the keyframes. But there is no pixelation inside it. And no proper keyframe gui.

This still effects me in 0.9.8. on ubuntu 14.04 64bit I thought it might have been fixed because the release notes said some keyframe issues in some effects were fixed.

according to XML effect description, obscure is not supposed to be keyframable?!

hum, sorry, "geometry" properties can always be animated. however it seems this functionality is becoming deprecated in MLT? (in favor of mlt_animate)

obscure filter has geometry "fixed", so the bug it that the on-monitor rectangle/path editor allows you to move!
I believe I saw somewhere the way to do what you are trying but can't find at the moment.

you now are not allowed to break the fixed filter by wrongly adding keyframes.
I keep the bug open to think of finding a workaround (something to do with automask?)

continuing to discuss with mantis ;-)
in mlt/demo/mlt_obscure you can find the obscure filter is used in combination with region filter + composite.
so it is possible to have obscured zone from any shape with any trajectory
=> your mission (if you accept...) is to see what can be done with Kdenlive UI?!

So I just tried playing with region filter and I can not understand how it works. I can't find any doco on it. If you know how it works can you explain it to me - and I will add it to the manual
