Disabling scenecut detection doesn't lead to any particular artifacts, 
just general wasting of bitrate. (Effectively it _increases_ the number 
of I-frames, but without the corresponding increase in seekability. 
Because scenecuts encoded as P-frames are just as big as I-frames, but 
then you also add the evenly spaced I-frames due to keyint.)
