Looking for a way to freeze an HDMI feed so that the current image (a PPT slide) stays up on the projector/TV while edits are made. Any suggestions welcome.

- peterburkimsher 1y agoThanks, I'm aware of OBS. Ideally I'm hoping for an embedded system solution, rather than adding more software to the workflow.
- k33l0r 1y agoI haven't used one myself, but I believe that something like a Blackmagic ATEM Mini should be able to do that (and much more). https://www.blackmagicdesign.com/products/atemmini https://www.blackmagicdesign.com/products/atemmini
- mynameajeff 1y agoI'm not saying this is the most practical or affordable solution compared to a more specialized product, but if you definitely want a hardware solution, I do know (depending on your HDMI spec requirements) this would be achievable with any FPGA dev board that has HDMI In/Out. I can't say I've worked on this exact solution, but I did some basic development with a Xilinx (Z7?) board years ago that involved overlaying and modifying an incoming HDMI signal. What you're looking for should be achievable by the same means assuming there's no signal issues I'm failing to account for.
