BTW I'm running this in 64 bit.

OK, I finally had a chance to look into it some more. I'm seeing 2 big problems when running in 32-bit. You need to tell Core Graphics that the byte order is 32-bit host order (in addition to pre-multiplied, alpha last). Then, after you've done the work, you also need to swizzle the color channels from RGBA (the only order that Core Graphics will accept for 32-bit rendering) to ARGB (the order that Motion expects to get back). I'm updating the sample right now. I'll send you an updated .mm file later today after I've checked it with some other people.
One thing, though - I'm only seeing color channel order problems. I'm not seeing any garbage like you are. I wonder why? What size project are you testing with? I've tried 720p and NTSC DV, and don't see any issues. I had thought it might be a rowBytes issue, but I would have thought testing at DV size would have caught that.

Hi Darrin
Any idea why this isn't working properly? Motion bug, SDK bug or another issue?
thanks

Thanks for the update. I'll add the new info to the bug.

So I found out the error was specifying kCGImageAlphaPremultipliedFirst rather than kCGImageAlphaPremultipliedLast.
This does stop the console errors but the result on screen is just a different type of garbage https://skitch.com/martinjbaker/fgppd/2ndtest
Same garbage pixels issue happens with the Scrolling Rich Text Example as well.
thanks

I'm trying to get the CGFxPlug example running but not having much luck. It builds fine and appears in Motion 5 as a generator, but when I add it to a new project, rather than a red rectangle I get this https://skitch.com/martinjbaker/fgj7w/cgfxplug
This looks to me like a bug in the sample code. Please file a Radar for it. I suspect I know what the problem is. I'd bet that we're not properly setting up the CGContext for 32-bits per channel or something like that. (That's just a guess from looking at your picture - I haven't actually debugged it yet.)
