i'm mostly converting 4k from a phone to 1440p and cutting [backup] storage by 6x. most of these vids are < 3min, and i can do quite a few in a batch job overnight. im in no rush. it does about 4fps with the 1080p30 HQ preset with the only additional change to up the res to 1440p. i would not use it for batching feature length films, but you can do one in a pinch :D
