Kdenlive 0.8.1 SVN 5751

I'm new to Kdenlive. Therefore, I do not know if a recently-discovered behaviour of Pan & Zoom is by design, or is a bug.

1 Drag a clip onto the timeline
2 Add Pan & Zoom effect
3 Add a number keyframes & set parameters for screen at each keyframe
4 Change the duration of the clip

...and all the key-frames added just disappear. Is that designed-in behaviour?

I needed to be able to extend that clip yet keep all the existing settings, so I did an experiment:

1 Copy the existing project with Pan & Zoom, key-frames in place:
$ cp ei.kdenlive ei-test.kdenlive
2 In `ei-test', change the clip length & save the project
3 Check the diff:
$ diff ei.kdenlive ei-test.kdenlive
...

4 Copied the original line 320 back over the changed project file in gedit

...re-opening Kdenlive, the test-project opened fine, and with no errors. All the original keyframes were back in place, but the clip was now at the length that I wanted. It was a bit of a hack, but has allowed me to continue with my work. I think it also answers my original question:- this is a bug.

hi

do you think that vi is the usual way to do video editing ?

but if you find a bug you do a good think !
