I encountered the same bug after importing a video stabilized with this command:
``` transcode -J stabilize -i art-01.mp4 -y null,null -o dummy transcode -J transform -i art-01.mp4 -y xvid -o art-01-stable.mp4 ``` Removing the clip didn't bring back my tracks but the preview is fine. -- You received this bug notification because you are a member of UBUNTU - AL - BR, which is subscribed to OpenShot Video Editor. https://bugs.launchpad.net/bugs/1073844 Title: Thumbnails, clips and tracks gone (but preview is fine) Status in OpenShot Video Editor: New Bug description: I use openshot 1.4.3 from the bazaar repository on Ubuntu 11.10. I accidentally deleted a cut part of a clip on a track. Afterwards I pressed ctrl+z to undo this change. The clip was restored but at the same time all thumbnails from the project file window, all following clips on the same track and all tracks on the bottom of this clip's track were removed. I thought it was just a display glitch as the preview still worked just fine. Thus I saved the file (as I made many changes from the last save) and opened the project again. Unfortunately the following error message pops up: There was an error opening this project file. Please be sure you open the correct *.osp file. The command line shows the following text: /home/myusername/openshot/openshot/classes/sequences.py:781: GtkWarning: gdk_pixbuf_scale_simple: assertion `dest_width > 0' failed new_pixbuf = pixbuf.scale_simple(remaining_pixels, height, gtk.gdk.INTERP_NEAREST) Traceback (most recent call last): File "/home/myusername/openshot/openshot/windows/MainGTK.py", line 2508, in on_hsZoom_value_changed self.project.Render() File "/home/myusername/openshot/openshot/classes/project.py", line 221, in Render self.sequences[0].Render() File "/home/myusername/openshot/openshot/classes/sequences.py", line 171, in Render MyTrack.Render() File "/home/myusername/openshot/openshot/classes/track.py", line 94, in Render MyClip.Render() File "/home/myusername/openshot/openshot/classes/clip.py", line 287, in Render self.RenderClip() File "/home/myusername/openshot/openshot/classes/clip.py", line 1163, in RenderClip pixbuf_width = pixbuf.get_width() AttributeError: 'NoneType' object has no attribute 'get_width' Thumbnails, clips and tracks are still missing as described above but the preview works fine (the project file has not been moved to another location). I conclude that the project information is still there but is not displayed. Unfortunately the project is not editable for me that way any more. Please help me to fix this as I already put several hours of work into this video project. The project file is attached. Please tell me if you need more information.
