I added a 1-minute clip into a keynote presentation and I connected to a video projector. Video format is DV 720x480, Millions, No compression, 29.97 FPS. The movie plays sluggish if I enlarge it.
Keynote presentation is set at 800x600, and my laptop is a Titanium 400 Mhz - 8Mb VRAM. I set the display resolution at 800 x 600 and thousand of colors.
However if I play the same movie full screen through Quicktime player, it runs smooth.
Does anybody have any idea why?
