Quicktime - playing 1080p 60 fps from a Sanyo Xacti HD2000
I've recently purchased a Sanyo Xacti HD2000, and I've got a question about playing back the highest resolution (full HD, 1080p at 60 fps) in Quicktime - basically, it doesn't work! I've posted a video of this symptoms here: http://www.vimeo.com/7999031
From reading some other posts here and on Vimeo, some people seem to suggest that this is because the computer doesn't have sufficient power to deal with this resolution of video, and you would need a quad core processor to play it back. Is this right? It seems a bit surprising - the computer doesn't seem to struggle to play it (other than all the weird artifacts!) and the CPU doesn't max out when I attempt to play the video.
I've also (I think) been able to use MPEG Streamclip to export the video into a .mov file at 60fps, and this seems to play back ok (though I'm not clear whether it is in fact playing back at 60fps properly).
Does anyone have any insights into this? Better yet, does anyone have any solutions?! (Other than not shooting in 1080p60 I guess...!)
Thanks,
Chris
