Hi bandicam,
I really enjoy using bandicam and some of its unique perks (like lower cpu footprint), however it is missing one cool feature that is available in other video recorders like fraps and xfire. It may be called different things in other video encoders, such as Record loop, loop buffer, or flashback.
basically, flashback will save a certain amount of frames (e.g. 15-30 seconds worth) in the ram, when you start recording it will write what is in the ram, and continue recording the live gameplay.
Basically it will allow you to start recording after something "cool" happened, and still have the "cool" thing in the video.
Please consider implementing this in a future revision, it is quite useful!
