3rd party preview views (Blackmagic Decklink)

It would be great if the previews could be viewed by 3rd party hardware like a Blackmagic Decklink card. Also have all parameters saved as presets including cropping

I clarified the title a bit, please edit for clarity if needed. You will want the title to be clear and specific so users can quickly see the idea and vote for it.

Thank you, that’s perfect.
