Bug Description

After cutting a clip some parts of the clip become black.

1. Ubuntu 12.04 64-bit Dutch
2. OpenShot 1.4.3-alpha3

Steps to reproduce:

1. Drag a clip (movie or image) to the timeline (any format)
2. Cut it 2 times
3. Push play or drag the playhead

Result: some parts of the clip shows only black in the preview window

As far I can trace it back, this is introduced after version 1.4.3-alpha1 of OpenShot.

Thanks for the bug report, I can reproduce this. It's related the new "Length" attribute we have added to the XML. I'm investigating. Thanks!

Ok, thanks, I just found out that it also ocuurs with the trim function: if you trim the clip, it turns black at some point.

Yep, I see that also. I think I might have just figured it out. I just checked in a "potential" fix... but I'm still testing it.

This is now fixed. But apparently it broke the original bug, which caused us to add the "length" attribute in the first place. So, I'm moving on to that bug now.

That's great, just tested the cutting and trimming and it works again without errors, thanks! Also exporting works, so I don't know what the other bug is but all seems fine.
