0002805: Crash on applying filters to "stabilized" mlt videos.

Notes
(0008554) marcinm (reporter) 2012-10-28 20:41 edited on: 2012-10-28 20:43	Kdenlive crashes even on cutting such a film - it's enough to drag onto timeline a stabilized video, apply zoom and pan (Polish "przesun i zbliz", settings width 1300, height 720, size 101,5% checkbox allowing for distorting is checked, background color - black) filter and then cut this video. Kdelive crashes every time I try this. This is 100% reproductable on this project.

(0008556) marcinm (reporter) 2012-10-29 08:59	No, I happens only on 0.9.2 that I use on daily basis (great product!). Maybe in git versions it has been fixed. Sorry I cannot experiment on a production system. Neither I would install an experimental version onto it. I think that this bug has something with processes that start immediately after drag a video onto timeline. If I leave project for at least 15 minutes after import and drag onto timeline, it works. Strange.

Tried 15 times, crashes 15 times. I can tell that video stabilization cannot be used in kdenlive, because it makes this application totally unstable (with segmentation fault as noticed in crash reports).

(0008792) ptitmain (developer) 2012-12-15 17:43	I am testing stabilization with "transcode" method and kdenlive 0.9.3+git20121211 + melt 0.8.7+git20121211. I have no issue combining a stabilized clip and the pan and zoom effect (using transcode or videostab). But, I have a similar problem here with stabilized video and the speed effect. I am currently testing with Steps are: - stabilize a video using transcode method - put the .mlt generated clip into the timeline - add a speed effect to 120% or 50% putting 120% reduce the clip to a width of zero putting 50% makes kdenlive crash
