The QxControl User Manual has an expanded explanation of Timelapse, from explanation to configuration and use. But Here we will talk about the export of tiemlapse video that has been recorded.
Exporting Timelapse footage will be very similar to exporting standard footage in Timeline. There are however, a few additional options we want to make note of in this section. To get an export started, choose Create Clip (scissors icon). Next, provide a name for the clip, and then toggle the “Is Timelapse” option to “yes”.
You will then see an option for “Timelapse Duration”. This means how long the clip will be after exported. This is NOT the range of the clip. Example, I want to set a range for three days of Timelapse activity, and I want the exported clip to play for 25 seconds. This option will make that exported clip 25 seconds in length. 
This clip will then appear in the Clips, accessed via the left hand menu.
