oh - the agenda-

well apple considers 'quicktime' as legacy - obsolete -

and so is removing it from all its products - and doesn't want any dependancy on it moving forwards- the 64 bit 32 bit performance hype is nonsense-

hence the removal of massive amounts of functionality for final cut X- all the 'legacy' stuff - the stuff that does things that people actually use...
like proper video capture- like proper video output- all these use 'legacy' obsoleted API - for which there is no equivalent replacement.
The reason they couldn't update final cut was - they killed the api's it relied on... but didn't replace them with anything anywhere near as complete


and replacing it with something that works on its iPhones and iPads.... making people use h264 -

well that causes a little problem for people who actually use quicktime to get things done.
