[Paul Dickin] “It seems to me likely that any future Mac Pro introduced in 2012 would need to have the latest iteration of Thunderbolt built in”
I’m not so sure about TB in a MacPro if it has PCIe slots. Think about the difficulties in merging the monitor connectively built into TB with a third party GPU. Would third party GPUs require a TB port? Then the high speed data connectivity would be the issue.
The easiest would be to leave out monitor connectivity, but that would confuse users when they plug-in the monitor and it doesn’t work. Can’t see Apple doing that. This whole issue may be why HP isn’t big on TB.
It may be issues like this that is delaying the MacPro. Would PCIe 3 solve it?… another reason for the delay?
I for one would gladly take an updated MacPro with PCIe slots and forgo TB. TB is an “on the desk” interface and PCIe an “under the desk” and “In the data center” interface.

[Spencer Iervolino] “This project was shot in 29.97 1080i. When I edit in 29.97 I get mixed cadences,”
You’re sure this was shot 23.98p/29.97i in camera? You are seeing 3:2 in this footage? It’s odd to shoot a live switched event in 24p/30i. If it is 30i native then you should edit in that format. If it is 24/30i then you will need to reverse telecine it to 24p.

One way to approach the problem is to segment your footage into discreet selects after FCPX transcodes everything and re-import. Take interviews: You would make selects of every question/answer. With your footage in smaller “chunks” FCPX MM becomes more efficient. It also speeds restore.

[Michael Gissing] “PAL SD will be interlaced from telecine. The two fields are identical”
Correct, but one should not be able to see any interlaced frames. They should be progressive frames created by two identical fields.
-
24fps film should have been played back at 25fps on the telecine producing no interlaced frames. Interlace means there are two distinct images making up a single frame. If you de-interlace a frame two ways: upper than lower are you seeing to different images or the same image shifted? I’d assume it’s the same frame as there’s no way to extract 50 images from 24.
If it is the same frame shifted it may be possible to shift one field over, returning it to a solid progressive frame assuming the amount of shift is constant. If you suspect it is the same frame take a short section with plenty of motion and de-interlace it upper and lower. Layer the two clips in FCP and set the transparency of the top clip to 50%. If you can shift the top layer so it matches the bottom exactly then they are the same.
Let me know if this is the case and I can tell you how to composite the two together and regain progressive frames without loss of resolution.

[David Cherniack] “AFAIK Apple has licensed prores encoding only to acquisition hardware companies (cameras, recorders etc).”
Apple has licensed Windows ProRes encode to Telestream for Episode and Vantage and Building 4 Media. I think Elemental has ProRes decode for Linux.

No need to transcode to 1080i interlaced. 1080p 29.97 “lives” inside 1080i 59.94 just fine unaltered. Remember the frame rate of 1080i is still 29.97, the field rate is 59.94. 1080i 29.97 is a more accurate name as there are 29.97 interlaced frames per second. Fields are just two images interlaced together into a single frame. In 1080p 29.97 there is only one image and a 1080i stream really doesn’t care.

You can continue to shoot in 1080p 29.97 as that is compatible with 1080i 59.94 broadcasts. Your graphics should match what you shoot and edit so they would also be 1080p 29.97.
The only reason to shoot 24p is if there are International deliverables.

[Weston Woodbury] “As already pointed out here, DaVinci and Autodesk both figured it out, and surely their video dept. budgets are substantially less than Adobe’s or Avid’s.”
Linux is fine when the software/hardware combo is a single entity and not used for any other apps. It’s more of an embedded system mind set that just is not flexible enough to run in concert with other apps. Few people use only Avid or Adobe software on their systems.
DaVinci and AutoDesk are perfect examples of a app/cpu single purpose “box”. In both of these examples having other software installed would probably need to be removed before support would begin to help you.

[Andrew Richards] “Apple will never license OS X. It doesn’t make any sense for them to license it. What’s in it for Apple?”
How about investing 101: Diversify!
Apple should not put all it’s eggs in the consumer space and rely solely on the “mob mentality” which can turn on a dime.
Apple stayed afloat serving the pro user and, given their wealth, wouldn’t put much of a dent in there current “fight to the death with google war chest” to continue serving them.
