Hey there,

For the first time while playing a 1080p Quicktime .mov trailer saved on my hard drive, I realised that incredibly only 20% CPU was being used as opposed to the crazy CPU spikes with other 1080p formats....

Does Quicktime 7 accelerate any other formats, or is it just .mov?

If so, is there a quick way of transcoding videos from other formats to .mov? MPEG Streamclip and Quicktime Export take an absolute age with other 1080p files!

Thanks for any help!

    Quicktime is for now needs a fast CPU and that is what you have...As for now as faster encoding for Quicktime, not really.

    Quicktime X that comes with Snow Leopard will take advantage of the video card for acceleration. And for encoding video too. This will make encoding faster. Leaving the cpu to take care of other business. Something that some of use have been awaiting for for a long time.

    Thanks for the quick reply man! Really appreciate it...

    So does the hardware acceleration currently only work with .mov files then? Because there is a clear acceleration compared with 1080p MKVs etc.

    Also, has Apple mentioned exactly which formats will benefit from hardware acceleration in Quicktime X?

    The new Windows Media Player on Windows 7 plays even 1080p .m2ts files at only 10% CPU thanks to the amazing hardware acceleration!!!
