Alternative to FRAPS for mac?

[Asele]

Just looking into LEGALY FREE alternatives to FRAPS for mac users. Without AV capture software, running at 42 ping with 100 fps on avg with all game settings maxed in most pre-VP raids. Exceptions: opacity for all spells is reduced to about 30% and /show 1 is normal to reduce clutter. Pretty much raid with everything else maxed at a resolution of 2560x1400. Would like to find alternative software that doesn't up my ping much if at all due to system resource monopolization while maintaining those same settings.

I'm running an early 2013 rMBP 15" on a 27" thunderbolt display with the game client running in a wineskin rather than a windows VM, although I am willing to consider the windows VM if that is necessary. Just drops battery life from 5.5 hours of gameplay in wineskin to 90 minutes with windows VM. I am unwilling to "permanently" commit HDD space to windows and use Bootcamp.

Suggested apps?
