[kdenlive] Problem with new keyframe import

[Harald Albrecht]

Hi,

I'm running into two problems with the new keyframe import system. Drag 
and drop with the new graphical display is great! Much more intuitive 
than the old Ctrl+Click method. This surely is another big improvement 
to Kdenlive usability.

In a test project I have a clip in my project bin. I then add an auto 
mask effect to the clip in the bin. Next, I run analyze so I get the 
movement data for keyframes. Then I drag and drop the analysis data from 
the properties of the bin clip onto an affine transition. The new import 
dialog shows up and I press okay.

Unfortunately, the imported keyframes of the affine transition are 
completely incorrect. Both a) temporal as well as b) in space (X, Y).

a) It seems that the temporal position of keyframes dropped on an affine 
transition is always relative to 00:00:00.0 of the source clip, but not 
relative to the beginning of the transition. For this to work, the 
import would need to know where to start from: either I'm missing here 
something important or there's a general bug in here. When I instead run 
an auto mask analyze on the clip region from the timeline, there are 
fewer keyframes, yet still incorrect in their temporal position.

b) while the import dialog correctly shows the X, Y movement data, all 
final imported keyframes have X and Y set to 0. Locale bug? I don't 
know, but these are integers, so there may be something else buggy here.

With best regards,
Harald
