what effects handbrake encoding times? or CPU power/usage in MacBook pros? today i began encoding a movie, i tried 3 different movies - and they all had the same experience - handbrake was quoting up to 6 and a half hours - even stayed this way after %25 of the encode was done. i knew something wasnt right. in my mind it couldn't be because the macbook was in clamshell mode in my 'bookarc' with the external monitor plugged in. but it seems it was! when i unplugged it and used it how i usually do - handbrake has not quoted the same encode as before as 3:32 for time. this is the same movie that it quoted me for 6 hours on. the avg FPS in clamshell was between 4-6. now in my usual use of the laptop its back up to 12FPS. what is going on?
