Add delay to SDI Matte from External Keyer

 

Hello Friends,

We just added Ultimatte 12 4K as an external keyer. I need to add delay to the Matte coming in on SDI. Reason being the camera fill feed is being color graded and pre-processed in Assimilate scratch. Obviously that is adding a delay on the camera FG feed. So is there an easy way of adding a delay to the Matte in the external keyer function inside of Aximmetry?

Thank you,

Ulf Soderqvist

Why not do the color processing in Aximmetry instead? You can apply a LUT in Aximmetry using the ColorMapper module and have lots of powerful tools for processing the image further. 


If you still want to delay the incoming matte you need to insert a Video Delayer module on the matte SDI signal before is applied to the fill in Aximmetry.

Thank you for your suggestion. Unfortunately it is not going to work as well in our workflow, since dynamic changes need to be made live. No possibility to post production. The color tools in Aximmetry are not as powerful. I have no idea where and how to insert a video delayer to chain of the Matte in the external Keyer?? That would be absolutely awesome and extremely powerful. I imagine there are many other users with similar wish.

Thank you, 

Ulf

Hi Malibuswede,

To add delay to the Matte, you will have to edit the camera compound.

First, you right-click on your camera compound and select Edit Compound In-Place:

Then double-click on the compound to enter it.
Find the Input compound you want to add delayed matte and select Edit Compound In-Place. For example, if you are using the first Input:

Then go to Billboards control board and right-click on the Input panel and select Go To Source Module:

This should get you near the Inputs, here you put a Delayer module on the Matte output pin:

In the Delayer module, you can easily set the delay in frames for the matte.
Also you can add this module to the control board so you would have easy access to it:



All the color tools in Aximmetry are live. Pretty much everything in the Flow Editor is live.
You can find most of the color tool modules in the Video->Postprocessing section of the Insert Module window:

Also, you can find some example color effect compounds in this folder: [Common]:Compounds\Colorizers .
All of these compounds are copyable and editable to your liking. Many of these compounds use modules that are in the Postprocessing section.

If you want to apply these color tools only on the billboard, then you can do the same as above with the Delayer. But instead, you put the color tool on the video output pin:

Warmest regards,

Hello Eifert,


Thank you for the excellent tutorial I will try it out today. When I mean colorgrading on the fly. I need a surface like this [see image] to simultaneously change parameters. Much like camera shading in any professional live broadcast setting.

Thank you,

Ulf

You can map many hardware controllers to Aximmetry to be able to do this. I’m also trying to petition Aximmetry and Pomfort (LiveGrade Pro) to integrate support. That would add a next level color grading workflow to Aximmetry for sure, and wouldn’t be complicated to accomplish.

True. It is just the the color grading in Aximmetry is a bit crude at the moment and integration with Assimilate, Filmlight or pomfort would be on top of my list. However, isn't pomfort Mac OS only?

Best,

Ulf

Yes, seems like it’s still Mac only, but the entire idea with LiveGrade Pro is that it can stream the LUT data over Ethernet, so it’s intended to run on a separate computer anyway. A Mac mini or lower end MacBook should be fine. A LUT is just a bunch of numbers, and since Aximmetry already supports standard LUTs it should be trivial to support getting that data as a stream instead of from a file.

Interesting solution. Eventhough I personally hate anything Apple. Lol

It’s just a tool. Just auto-start Live Grade and you’ll never have to see OS X ;-)

Hi,

We are thrilled to share that the latest Aximmetry update, Version 2023.3.1, now offers support for receiving LUTs directly from Pomfort LiveGrade software via a LUT Input module.

You can add the LUT Input module's Device in Edit->Manage Devices.

Warmest regards,
