I have two videos, both roughly the same spec:
A: H.264/AAC 1920x808 24FPS ~3015kb/s
Using Quicktime player I can scrub through this movie smoothly and with fine detail. Jumping from one position to another, playback will happen immediately.
B: H.264/AAC 1920x1080 25FPS ~3662kb/s
This video can’t seem to handle the scrubbing as well. Dragging the playback head hangs constantly, I keep getting a beach-ball when jumping from one position to another.
I realise that the data rate on B: is higher, but is there anything I can do to improve it’s performance other than re-encoding at a reduced data rate?
Are there any tools available other than VLC/Quicktime media info, that will show me more detailed encoding options so I can further optimise B: based on A: if I have to re-encode?
