How to setup and monitor IRE settings in Final Cut Pro
How do I view my IRE settings in final cut pro? Will broadcast safe setting ensure I’m within the range? I’m trying to output my video to the IRE standard of 7.5 IRE and have the Luminance below 100 IRE, and to have the Chroma levels not exceed 120 IRE. Below are the exact specs.
-Setup level should equal 7.5 IRE
– Luminance levels should not exceed 100 IRE
– Chroma levels should not exceed 120 IREThanks for the help!

Under the TOOLS menu…there are VIDEO SCOPES. That’s where you look.

Not always. It can be the last little bit you use to ensure you are good, but really, you should use the 3-way color corrector and Proc Amp to get you to where you need to be.

Maybe 7.5 maybe not… What type of video are you editing?

It’s a com. spot for a client out here. A specific delivery spec, it calls for “IRE” standards. I’ve mostly dealt with broadcast safe mode, not the scopes in FCP, or measuring IRE.
DO you know of a feature (or third party software) to help monitor IRE standards?
Thanks,

“Yes. As I said, the built in VIDEO SCOPES, in the TOOLS menu. They show you the indicators for all the IRE levels, including 100 and 7.5. Don’t know how to read them? Want to make sure this passes broadcast QC? Hire an online editor. Either have them do it, or show you how to do it.

You never answered my question. What codec are you editing? I ask, because 7.5 IRE is essentially the standard for legacy analog video, while the standard for digital video is “0” IRE.
Did the delivery specs call for 7.5 IRE specifically?

Forget about the 7.5 IRE in FC.
Those values are for the “analog world”.
The 7.5 IRE must be added by a video card when putting out analog.
You don’t have to add that to your FC image. Files exported with those 7.5 IRE will be wrong.
In FC you keep your Blacks at 0 and Luma at 100%.[John Martin] “- Chroma levels should not exceed 120 IRE”
That’s is not really “Chroma” but the Composite signal, which can not pass 120 IRE.
You can not properly monitor the Composite signal in FC. The top value you can read is 110 IRE.
You need an external scope to set this properly, however you can easily set the FC’s “Broadcast Safe” filter for those values.

Do you not know what this is? Are you the editor on this project, or perhaps the producer? I would expect an editor to know what this is, and how to evaluate it.
OK, are you delivering for NTSC (that would be weird) or ATSC?
And actually IRE specs can include a lot more than just luma/chroma levels. What about front/back porch, blanking, sync, burst levels, what line test and reference signals are embedded in, etc?
IRE as a unit of measure is one thing, but as a spec or a standard it is a lot more.Scott Sheriff

https://www.sstdigitalmedia.comI have a system, it has stuff in it, and stuff hooked to it. I have a camera, it can record stuff. I read the manuals, and know how to use this stuff and lots of other stuff too.
You should be suitably impressed… -
I wish the IRE terminology would just die a horrible death and go away. It has no relevance to anything anymore.
Digital video is digital video. 16 is 16. 235 is 235. There’s no IRE involved. Ever.

Those specs are for plain NTSC when broadcasting or printing analog (Betacam, I”, U-matic..).
What you have been watching at home for more than 50 years.
You need a video card an an external monitor.
