Hum you seem to have a problem for encoding more than 5 hours for less one
minutes. After that, it is normal that you have a file of ...............0
mb. :-(
Update your version of mlt; Even it is for Ubuntu, this faq eve can help
you  https://answers.launchpad.net/openshot/+faq/1861
After, I wondering if you should not update ffmpeg, like you are on Debian
I'm nearly sure that you are using this dirty fork : libav or avconv full
of bugs.
For the cursor it is mlt, for the export ffmpeg even mlt can be the issue.
