Re: first impressions of QC

ouch, reading between the lines does that mean that we won't be getting these kind of features because they can't be handled by the Quicktime player framework?

No, no, I just meant that one of the goals for the first version was to be able to take a composition and ask it to render a frame at an arbitrary time as that simplifies support in QuickTime. But it's true you can always create compositions that are not deterministic if they download data from internet or depends on user input. So it comes down to defining conventions, I guess.

also, just curious and I realise you might not be able to answer this, will future Quartz Composer releases be only limited to os releases (ie a future version will come bundled with  10.4.x ) or will it be updated separately to the OS?  i've just realised that tiger included an API freeze which means I'm now horribly scared that you can't update the QC api in a way that would break applications that use it, does this mean what we've got is it?

The general rule is that 10.x.x updates only have bug fixes and new features are reserved for 10.x versions.
Furthermore, binary compatibility must be preserved, so yes, updating the API in a way that would break older compositions is not acceptable. However, new patches or features can be added in the future, but composition files that use them won't run properly on older Quartz Composer releases.
