Editor crashes with some video inputs

[lkiesow]

We have some instances where the editor completely crashes when trying to edit a video:

• Pausing the video playback in the editor will jump back to the beginning
• There is no background for the timeline
• Seeking (after playback) will crash the whole editor

My guess would be that this is caused by duration bein null in edit.json.

[lkiesow]

Can confirm that the problem is the missing duration
