Scaling large images down quickly (Premiere)
The only real problem about the way Premiere handles images? It brings in all of their beautiful megapixels - but the scale is at 100% - meaning large pictures are HUGE - with their edges far outside of the frame area....
....unless you select them and choose Clip > Video Options > Scale to Frame size.
Then all of them are scaled down (making it easier to animate!)
