Using the latest AUR developer version (1.0.1.r3.g621) (on Antergos Linux) the program opens and runs just fine but after I am done recording and the encoding/processing occurs my system comes to a halt.

My CPU is at 99% (intel i7 4770K Quad Core) and my RAM which would be 3/16GB is now using 15/16GB. It then takes almost 5 minutes (if not longer) for the recording to actually finish processing.

The video ends up being fine, but I must say it being 15MB is a bit much (not sure if this is related to the issue or not). I know of other software that does the same thing and the same length video would be 1.5MB.

Hoping there are some logs I can find for you to help you figure this out. Let me know!
