I have a similar problem - when I try to record I keep getting the message UNABLE TO RECORD CHECK ENCODER OPTIONS.
I jiggle around with the frames per second and ticked record in low quality but get the same message each time .
I cant find any help anywhere to get round this - so far spent two hours trying to make a five minute tutorial video.
I am on the point of uninstalling and trying something else
Moderator can you post a solution to this
