Hi, I'm the author of [fiveLoadSub](https://github.com/wilsonlmh/fiveLoadSub/), a HTML5 based subtitling software. It's great for ATEM to have network capability. I think it's really easy to build a online-subtitle-keyer software by utilizing the media player of ATEM. And it will be even more easier with javascript. May I ask for a new feature to write the media player(currently only stills with alpha channel needed)? Thank you!
This seems like a nice idea!
It is not so easy to implement though. But after looking at the specs from skarhoj, I think it is technically possible.

I think you need to export your subtitles as a sequence of PNG's and upload this sequence to the ATEM. Then you can switch between subtitles by setting the current frame of the media player.
For the moment I have no idea how to upload images to the atem, so this will take some time to investigate...
I have not much time to do this right away, but it seems like a nice addition. I will notify you when I have time to implement it and you will be the first to know when its done 😉
Is also an alternate solution for #3. At that time, we solved the problem with a little computer (like Raspberry Pi) that rendered the (sub-)titles in a web browser and brought them in to the ATEM via an HDMI input and a simple keyer.
