Anyone know of plugin for Premiere Pro (relative newcomer) that will allow me to zoom in and pan on a 4K image in an HD timeline as if it was live. I could do it all in the motion tab but the feather gets tough.
Not aware of any plug-in, I just use Adobe Motion with keyframes. Ease In/Ease Out can help create natural-looking movement between keyframes when starting and stopping "camera movement".
If I want to cut between different shots, like wide to close, I will place a CUT in the video clip and just have different position and scale settings between the two clips, so no keyframing needed there.
