Just tried the new Dec. 07/13 built From A.D.

There has been a lot a changes, and we are going backwards,
The performances is still very poor, lucky to get 70MB/s
@ 1872x1012 23.976, 1500 frames,
Compared to the Best Built to Date
Oct.24th 2013 at 1872x1012 23.976 I Get 42 GB or about 14,000 Frame ! at 75.5MB/s
There is No Recording Frame white rect., where did that go ?
just that
ulgy Black Box.
The interface for raw record monitoring has change for the worse,
There again Oct 24th was better , it did not get in the way of view the Lv.
In the Preview Menu, when you select Canon preview mode it would before in Oct 24th built
It would turn all overlays off and leave the raw interface with buffer only displayed.
But now there is 2 semi transparent Bars upper and lower that can't be removed.
Now there is No more Clean HDMI out, unless you turn Off all overlay ,And or Global Draw Turn Off.
So with that you have no Idea on how much space free you have on the card or if the recording is about to Stop.
If I what to Use my Ninja hdmi recorder to Backup my raw recording I have to Turn Off All overlay then Record.
Before on the Oct 24th built with a hdmi recorder connected to would get a Clean out to the recorder,
With just the Raw interface in the UpperLeft hand Connor of Lv that could be crop out if needed.
Unfortunately I did not Check to see if the 42 GB Wall is broken, For I Have returned back to
the Oct 24th built, its looking like there is no more improvement that can be make to that built.
Its really looks like the 5D2 Can Not Handle the Global Draw On with Raw Recording.
I do not think that implementing a universal Global Draw on for all Cameras, is the right thing to do.
My Vote is to Go Back to the Oct 24th built Style of interface and functionality, (eg. proper hdmi support)
But I think the Dev. are trying to push the MLV format on the 5D2 and it will not work will, just not enough CPU!
There is just enough CPU to maintain the present raw format as it is in the Oct 24th Built.
Please I don't what to Sound Negative About this update and all the Hard work everyone has
done, but I would always choose to have Better Raw recording speed and large frame sizes over
Convenient On Screen displays (eg. Global Draw stuff) considering just about all Field Monitor have
Pecking, Wave from display etc... .
