  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Calibrated for broadcast.

I am thinking about an AJA IO HD connected to a plasma calibrated of course....
The goal is to output to HDCAM.

With all those QuickTime gamma problem...shifts, would it be a good solution ?

thanks
 
Hi there, if your goal is to take the HDMI out to the HD/IO box, it doesn't seem to work. The pixel count of that output is non-television and the box won't see it.
You can get a clean 720p/60 output from the HDSDI in playback that could be recorded on DVC-Pro HD but without matching timecode.
 
Hi Keith,

I use FCP Studio 2.

I want to use the AJA IO-HD only to "see" a calibrated image (black leveles, gamma, colors) only.
It won't be used to connect to the HDCAM.

The HDCAM bumping of the final product will be made via a QuickTime file or a TIFF sequence on the client's AVID DS.

So my only concern is to edit and color correct with a properly calibrated system.

thanks
 
Yes I think you will get very usable output from the HD/IO box from FCP it works very well. Nothing beats a broadcast monitor but if you are careful and have a good plasma it will be close, much closer than the typical computer monitor.
 
Take what you see on the plasma with caution and judge what you are looking in the monitor looking at the waveform
It's not ideal but if you can't have a broadcast monitor it can be a solution

another idea for using HDMI for monitoring is

Much cheeper and if your intent is only to monitor an HDMI signal.

In this case you shouldn't work this way.

monitoring a HDSDI or HDMI signal doesn't mean you are working in a calibrated workspace.

It's the media you use to display the signal that has to be calibrated.

A broadcast monitor should be calibrated almost every time you use it.
Broadcast monitor has specific tools (that other monitors don't have) you have to tweak to calibrate it
Basically you feed the color bars you need and use the various knobs and buttons to calibrate the monitor so it display the colors and gamma correctly.

Hope this helps

Just so you know, I was hoping to use the Intensity Pro to monitor HD footage in both HD and downconverted to SD....However, I found out that the Intensity does not support 24P! Since I believe most people will be shooting and editing in 24P, that leaves the intensity out of the picture. I will be probably upgrading to the DeckLink HD Extreme very soon as it supports 24P (granted it doesn't support HDMI...)

Another thought is... why not just buy another graphics card for your computer and hook a LCD/Plasma up via DVI or with a DVI to HDMI converter? That seems like a fairly cheap solution.

Matthew, will you be working with 1080 or 720? Decklink Extreme does not support 720P 23.98. Only the 1080 signal can do 23.98. You probably already know that but just wanted to point it out if any other were thinking of using 720P 23.98, it won't work.

Well, I was planning on working in 720P for most corporate stuff, but I guess I will have to do 1080P. It's really interesting what Blackmagic does support and what it doesn't support....sigh....

What's weird is that I was using 720P 23.98 in an earlier version of the firmware and it would do the conversion to SD 29.97 and HD 59.94 but in recent builds i have had problems. NTSC monitor would have image flashing, etc.

I would call the Black Magic folks and ask them what is supported in their most recent firmware. Last time I checked they told me 720P 23.98 was not a supported format.
 
Thanks for the info on the BalckMagic solution.

Michele, i am familiar with monitor calibration, but i wanted to see if a plasma can actually be calibrated close to a broadcast monitor.
 
Hi Antoine

Maybe but without consistence for sure.
Which tools would you use to calibrate your plasma?

The Intensity will display any 24p timeline as 60i, which doesn't affect color in the least. The only thing it changes is that the displayed image has 3:2 pulldown - but then again, so does essentially everything you see in HD on any broadcast network.

The Intensity is a very good and very inexpensive way to monitor HD output, regardless of what your timeline is.

Are you saying that the Intensity on the HDMI will support 24p? (really as 60i) When editing on a 720P timeline in FCP going out to a SD downconvert it does NOT support 24P. All it gives me is a freezeframe of the first frame:(

maybe your problem is here, you should try to go directly to the HDMI port of an HD monitor

That's how mine is set up, and yes, it works fine. Although frankly, the analog downconversion should work just as well. You should check the Intensity control panel and consult the manual to confirm the setup. Be aware that the Intensity does only send out interlaced images, so if you're playing either 1080 or 720 at 23.98, it will add 3:2 pulldown and output either 1080/60i or 720/60p, depending.

Well, the Intensity Pro doesn't:( I talked with Blackmagic Design's tech support right after I got the card and they confirmed that it/FCP will not down convert HD 23.976 on the fly to SD. All it will do is give you a single frame. After Effects will support all resolutions down to SD, but that's because AE does it, not the card.
