Hi guys,
I would like to know how to get a PowerPoint presentation to work inside of Aximmetry. My initial idea was to use a screen capture node, but I don't know if that would be the easiest way of doing it. I have setup a virtual screen and connected the capture node to it, which captures my main display just fine. However, I want to capture the HDMI output from my second laptop (where the PowerPoint is opened) instead. I'm not sure what I need to connect to the screen capture node to make this work. What's the easiest way to capture the HDMI feed from my second laptop and display it on my virtual screen?
If you guys can tell me what to do with images that would be greatly appreciated since I learn much easier by seeing rather than reading. If not that is okay as well.
Thanks so much in advance to everyone who's willing to help.
Hi,
Instead of using a second computer (laptop), you could consider using an additional display solely for capturing the PowerPoint presentation. For this, you don’t even need a physical monitor. You could use a virtual display driver like this one: https://github.com/itsmikethetech/Virtual-Display-Driver
To capture the screen, just use the Screen Capture module in Aximmetry and output its video. The tricky part is deciding which protocol to use to transmit the video to another computer.
If you want a very reliable system, you should use a physical connection between the two computers through HDMI and use a capture card on the receiving computer. Note that HDMI has a distance limit. More information on capture cards can be found here: https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/supported-hardware/pc/capture-cards/
Alternatively, you can consider sending the video through the local network using SRT: https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/supported-hardware/pc/capture-cards/
Or NDI: https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/setting-up-inputs-outputs-for-virtual-production/video/ndi/ndi-in-output-setup/ (Note that SDI is not available by default in the Studio version; you need to rent NDI ports for it.)
If you are not using a multimachine setup:
On the laptop showing the PowerPoint:
Add a Screen Capture module and expose it to the right side:
And set it as the output in the Edit > Video Outputs window:
On the receiving computer:
Add a Video Input module. Specify your capture card in the module and connect it to your virtual screen:
In a multi-machine setup, you could actually run your laptop as a remote machine and create separate logic for it inside the Flow Editor that will only run on that machine.Warmest regards,
