I have a Canon SX130IS and my SO has an A720. They both have the
option to record video. The SX130 records 1280 X 720 @30fps in h.264
format and when it is uploaded to the Mac, it appears as a .mov file.
Let's see, a spec sheet says "H.264 + Linear PCM (stereo)"
When I play the videos (from either camera) in Quicktime they're
horribly choppy. The host machine is an MDD 1.25GHz single
processor.
Before I go delve into the software configuration, etc. Does playing
this kind of video simply require more processing power than the MDD
can provide? Would dual processors make any difference? I have a
1.33GHz dual processor card from a Xserve that I could install.
Anybody playing videos from their Canon camera with acceptable
performance on a G4?
Apple's h.264 codec, in QuickTime, is not very good. Try VLC.
Use a tool such as Activity Monitor to watch the cpu and memory...
fwiw, I can play some h.264 on my 933-MHz QuickSilver G4. But,
depending on the compression used, sometimes it skips a bit even in
VLC. My solution then is to either re-compress it, or transcribe it
to something like mpeg-2, using ffmpeg.
