This exactly what I have found. Playback on a MacPro 3.33GHz, 6 Core 2010 Macpro and 24 GB shows the CPU idling at almost 80% when playing back a three camera angle Pro Rez 1920 x 1080 multi cam clip. Playback constantly drops frames and is even worse when an LHI AJA Kona card is brought into the mix. I remember this became much worse when FCPX 1.03 and 1.04 were released. By contrast a 2.93 GHz 7iCore IMac with only an 800 Firewire and 12 GB of RAM plays back the same clips without any problems

I am using ATI 5770s in both MacPro 2008. In the 3.GHz machine, I have an AJA LHI feeding a HD TV monitor. Performance is even worse when this is activated.
Incdentally, I just took the entire project and event files and hook them up to an earlier iMac….2.93GHz Intel Core I7 with 8 GB of memory and ATI Radeon 5750. The multi cam played fine! I was using a Lacie Big Disk Raid 0 (two 2 TB drives inside) and only FW 800! This iMac does not have thunderbolt.
Now I don’t understand why this work so well. Is it the processing power in the iMac? Seems like you don’t need a top of the line iMac

As I said, I am trying to find the line in the sand for MacPros and FCP X. Which MacPros cut it and which don’t

Footage is 1920 x 1080 29.97
Apple Pro Res 422As read under get info for one of the files in the optimized folder

Are you sure?
I have been running some tests with a gig I just did. It was three 5Ds, one hour and a half recital. All footage converted to Pro Res using FCP X optimized. Additional audio added in. Pluraleyes to Multicam clip.Loaded as a project and finished editing on the iMac. So then I copied ALL files to each of the Macpros. On one MacPro, early 2008. 2.8Ghz 16GB Ram, 0 Raid system reading 160 mbts/sec I was getting dropped frames continuously. I tried a similar equipped MacPro, early 2008, 3.GHz, and same trouble. Only with the IMac did the multi clip play without incident.
Now go back to my original question, will a six core, 2010 Macpro be able to do it? It is quite obvious to me the two early 2008 MacPros can’t because their processor power is not fast enough.
I love MacPros, but plainly there is a line in the sand where older ones simply can’t perform to the level of a modern day, fully loaded iMac. I am trying to find that line 🙂 -
The only solution I have heard about is to have everything synched as you have done, Then delete your video by break apart each clip. Then make a compound synched track of your audio, bring this back into FCP and synch again with your original video clips. Then in the angle editor you will have one loudspeaker clip for sound and whatever video cameras you have. You can break apart the compound audio clip to adjust the audio levels within.

It appears that the MXO2 when working with Premier CS5.5 on Mac Snow Leopard cannot handle multi clip editing too well. Despite my attempts to make it easy on the MX02 and Premier, by importing only Pro Res 422 LT files ..1920 x 1080 29.97, the resultant multi cam display of three tracks plus the time line is distorted initially and then becomes frozen.
A check of my permissions indicates real havoc. They must be run and corrected and my machine rebooted before I can do anything more with Premier.
Premier itself runs fine on my machine and does multi clip just fine too, but not when in a Matrox timeline.
Is this a problem with drives….and drive speed? My raid drive indicates a speed of about 120 Mbyts/sec. Maybe the MOX2 mini only works with raid drives capable of at least 250 Mbyts/sec
But maybe not, since things seem to work so much better in FCP 7.03
Maybe all the Adobe hoopla is really only for Windows users and not Mac users.
And, I really don’t think upgrading my OS is the answer at this point.

No, I haven’t tried, but I was wondering if you used a blank video clip for the entire length of the Zoom audio clip and marry them together somehow (not sure how to do this), would you be able to fool FCPX into treating it as a the base video clip from which it can synch all the other clips…I know that Pluraleyes has the same issue in FCP 7 if you are doing multi clip.
Would love to resolve this somehow…can’t find anything in any tuts or posting about this workflow other than here!!!

This issue is similar to one I am trying to resolve in FCPX. In FP7, I have been using multiple cameras and multiple audio tracks. I put everything on the timeline without edits and get Pluraleyes to match everything up. Works like a charm, BUT until recently I never used FP7’s multi-clip feature. I just used the Pluraleyes Sequence to reveal each camera as I wanted. I jused the razor tool a lot and j shorten clips to reveal others or used the edit function to cut out clips on a particularly track, always watching to see if my actions put me out of synch. I kept a Zoom audio track and deleted the audio camera tracks when they seemed a bit echoey or not that good, or I simply disabled the audio tracks. Not particularly fast, but worked for me.
So, how do you duplicate this work flow in FCP X..it seems from the posts here that it might be possible by following the steps here?
What would a do about the single audio track from the Zoom? Connect a Gap clip to it and make FCPX think it is a regular video clip that it can use as the underlying storyline?
When out on a shoot, I always audio record the whole thing in the best quality possible and use that instead of the camera mikes.

Import your 5D MK11 footage with the Canon plug in and top resolution. Use an HV30 or HV40’s HDMI output to capture the XHA1 footage at the same resolution. When you do this, there is less rendering for FCP. You will need an import card to feed in the HDMI signal. I use the Matrox Mini. You don’t have to do this but it makes for easier editing and less rendering.
