    Santa got me a new 5G 60 Gb iPOD couldnt wait to get all my episodes of "tripping the Rift" on there. :p

    30 Min episode the dam thing is still trashing away after 3 hours (only 50% done) and the CPU fan is going like an industrial vacume cleaner. :eek

    Thought this iPOD video idea is a total sham.

    Searched the net and got this freeware "iSquint" converted it in Real Time with no dramas :eek:

    Quicktime Pro a bit like .Mac wish I hadnt forked out all the money now :mad:

    The h.264 codec, used in QuickTime Pro 7, is very complex and takes lots of cpu power to encode. Thats the reason it take such a long time.
    iSquint use a different codec, x264, which seems to encode faster than h.264. I dont know if the quality is comparable though.

    I'd agree Quicktime Pro is a pretty awful app. There's a bug where when you export non-square DV video, it comes out as 320x213 and doesn't recognize DV pixel aspect ratios. The slowness, as the above poster mentioned, is due to H.264 and as yet, until it can interface with a video card GPU, it shall remain pretty slow, even on a dual G5.

    You can try Podner can encode to MPEG-4.

    At the moment I am trying various compression levels and also with with H.264 ticked in iSquint and its still making a much better job of it.

    er um comparable quality on an iPOD screen:eek:
