Hi guys,
I am a bit concerned with my ability to deliver/playback HD footage.
Right now, most of my delivery is DVD (easy as I just convert to SD) and web.
For web, the sweet-spot for me is to compress to a pretty low res file and use H.264 which gives really really nice results for small file sizes.
However, I am reaching the point where I might need to deliver full HD-sized files for some short films.
I tried encoding H.264 at 1920x1080 (although for some reason, FCE reports it as 1880x1060 or something odd). I chose a bitrate of 10,000 bps (average) and high quality.
OK, so I get an 88M file for my 1.5 min movie (not wretched) but when I try to play it back on a dual 2.0G Mac G5 with a 24" LCD, I dont think I have the horsepower to actually play it at full frame rate -- the footage looks very jerky and disorienting.
When I play back the smaller files, they look great.
So does anyone have any suggestions on how to encode for great playback on machines with reasonable CPU power? (Or maybe I am just doing something wrong with the encoding)
