I could try this myself (as I have Final Cut Pro X), but have you noticed any degradation in performance when using ProRes 422 in iMovie '11 (assuming you've tried it of course AppleMan)? In other words, does iMovie perform just as smoothly as when using Apple Intermediate Codec as the editing format?
I guess it will depend on hardware. My MacBook Pro is getting a little long in the tooth, being an Intel Core 2 Duo (2.66 GHz late 2008/early 2009), although I do have 8 GB Memory and dedicated Graphics - NVIDIA GeForce 9600 GT with VRAM 512 MB. Final Cut Pro X works reasonably well with this setup (a little slow), so I guess iMovie will cope OK with ProRes 422.
To me it looks slightly better than AIC, but I am not sure I could pick it out in a blind taste test.
Karsten says he has noticed some quality issues with titles. I don't think either of us have tested extensively.
Once I had Final Cut Pro, it made sense to use Final Cut Pro on most things.
For all my iMovie Events and Projects, Final Cut Pro can see them as AIC and edit them.
For any new shoot, I do a camera archive and import into FCPX. Then I usually edit in FCPX. But if I need to do something quick and dirty in iMovie, I would import the ProRes files to an iMovie Event rather than reimport as AIC.
Hardware could make a difference at the edge cases, but for most, it should just make it slower.
There are two theoretical advantages to ProRes 422, but in my view, they do not make a huge difference for iMovie.
1) You get chroma sampling of 4:2:2 rather than 4:2:0. But does this matter, since my original AVCHD files are 4:2:0 anyway?
2) You can do multiple renders of the same clip without losing quality. But with iMovie there is only one render pass.
I haven't done extensive testing on this, and given my backlog, I probably will not anytime soon. If you do, please post!
My gut feeling is I could get a better quality improvement by moving from my interlaced camera to a progressive camera than from editing in iMovie in ProRes. But that is an opinion uncluttered by data.
Thank you very much AppleMan for that very useful information. Unless I start using Final Cut Pro X more, I probably won't have a requirement to use ProRes in iMovie. I was just a little curious as to how well iMovie handles it, in the event that I ever need to use it. But, as always, our own individual testing is the best way to go I guess!
I have edited a few projects in Final Cut Pro X using ProRes 422, but am still coming to grips with it. I feel more comfortable with iMovie '11, so for the meantime am continuing to use it for most projects (I have a huge backlog as well - perhaps we spend too much time here!).
iMovie handles the type of projects I work on very nicely, and I probably don't need all the extra bells and whistles available on FCP X. Having said that, it does have some fantastic features (way beyond iMovie), which have recently been complemented by the update to version 10.0.6 (Chapter Markers is a minor but welcome addition). All the pros must be feeling much happier with it now, as it must be close to fulfilling all their needs.
All this has got my mouth watering to start some new projects in FCP X - as they say, practice makes perfect! I've been reading (and bookmarking) Larry Jordan's FCP X articles mentioned in his newsletters - that's keeping me in touch with how to use many of the useful features
Thanks again for your valuable comments AppleMan, and apologies to the OP for getting off topic slightly!
Hi John. I have tried Larry Jordan's training, the MacBreak Studios stuff (really good), and several others. I have found that I keep going back to some manuals from a guy named Rothermich that are quite good, and if you get them in a bundle, they are not expensive. I hop he updates them for 10.0.6.
Thanks again AppleMan! I've purchased Edgar Rothermich's FCP X Bundle 1 comprising 3 separate PDFs - a massive amount of information, clearly presented, well illustrated, and certainly great value ($7.99 for the full bundle - hard to pass up).
A quick look through shows that Edgar has put a huge effort into producing the manuals, with attention to detail. Now I just need the time, patience and energy to work through them, perhaps just concentrating on the main areas of interest. Sigh - looks like my backlog of projects will keep growing.
hello john.. i already understand that you have the same same laptop that i...
but i have so many crashs with fcpx...
do you install any special driver for "our" geforce???
i can't find any driver... and some people tells me the fcpx works with open cl..
the fcpx are the only software in my macbookpro with crashs...
No, I don't have "any special drivers" for the NVIDIA GeForce 9600 GT graphics card - just whatever came with the MacBook Pro.
When I use certain effects in Final Cut Pro X I do experience crashes (but can't recall which ones caused the problem, although I think Bokeh Random was one of the troublesome ones).
This article by Larry Jordan may help to solve the crashing problem:

Hope this helps!
