Hi folks – here is an exchange I had with Canon support with respect to metadata in the hdmi stream. I was looking for metadata on focal length, aperture, and iso using Canon EF glass:

Dear Mr. Scott Williams

Thank you for your E-mail inquiry regarding the Canon EOS C100 Cinema Camera.

HDMI out footage will not contain the Metadata you require Scott. As a workaround what you may try is, towards the beginning of every shot/scene, you can set the camera to display all of the onscreen information. This will then get recorded to the external recorder. You may then turn off the display information and start the recording of your intended scene. This will then serve as a record of many of the camera settings for the scene you’re recording Scott.

Should you require further assistance, please feel free to email us or visit our customer support website at https://www.canon.ca

Sincerely,

Mike

Thanks for your quick reply Mike. I will follow up with Adobe and Atomos.

One follow up question with respect to the video information that comes
out of the hdmi port on the C100. Is it at least theoretically possible
for an external recording device like the ninja 2 to capture metadata. In
other words, does the video output from the C100 hdmi port contain
metadata (including those I described in my last email) which could be
collected if the recording device has that capacity. Let me know.

Scott.

Success. I actually revised the scale of the syntheses scene to 1 metre and everything works.

Thanks again. This site is the greatest.

[Scott Williams]

Thanks Adam. I will give it a shot.

Is it just a margins issue or is there a heat issue as well. Won’t 8 or 12 core CPU running at higher clock speeds than the Apple cards have a potential heat issue?

[Scott Williams]

I assume the point of the release was to maximize speed and performance, particularly with the dual fire pros in the mac pro, rather than feature upgrades.

[Scott Williams]

Is after market RAM generally considered very risky? Still trying to decide if I put my budget into Apple RAM when I buy.

[Scott Williams]

I got a call from an Apple Business team member yesterday who asked if I wanted the Mac Pro before the end of year and asked me to specify the configuration I was looking for.

Thanks Walter.

I just saw that same point referenced on the Tom’s Hardware site contrasting the quadro and fire pro cards. Half of learning about a system appears to be learning which information sources are trustworthy.

Here’s what I got back from Maxon support.

Hi Scott,

I hate to say this, but don’t believe what you read on that fireprographics link.

Trust me when I say that CINEMA 4D currently does not take advantage of GPU rendering, whether it’s with an AMD Firepro card, or any other graphics card.
If you have one of two 3rd-party renderers, Octane render or Iray, then you can utilize this card for GPU rendering. However the renderer that comes built in with CINEMA 4D can not take advantage of the Firepro cards. This is not going to improve your Global Illumination render times.

For C4D purposes, the graphics card is only used to display the 3D viewport. So for fast animation playback, heavy scenes, and quick viewport rendering you will want a good graphics card. However it’s not required to run C4D. You can run the application with Use OpenGL turned off in your preferences to rely on the motherboard’s RAM and processors to generate the viewport display.

You’ll only see benefit from the Firepro card while rendering in the viewport (provided the graphics drivers are stable), because it is a high-end professional card. C4D uses the OpenGL capability of the card here, and does not use the GPU processing. For the cost, you may be better off getting a high-end gaming card for C4D use, since it’s the OpenGL capabilities C4D needs most from a graphics card.

I hope this helps clear up the confusion. Please let us know if you need any further assistance.

I put in a query to Maxon to get some clarity. See if they answer me.
