Fix a big that occurs when creating a demo with multiple "pauses" and "resumes"

Last night I experience the following bug: While recording a demo for my client, I had to pause and resume the recording multiple times, when reviewing the video, it looped randomly over distinct segments, normally on the segments in which I resumed the recording. While exporting showed the video as expected, it made editing and previewing really difficult, as it looped over 10 times per segment before continuing.
