Capturing stream original size while rescaling stream for Facebook

[zakwasny]

I can't find solution for this on forum - is there simple solution for capturing original 1080p image I'm working with along with streaming to FB. Facebook is limiting stream output to 720 and I want to grab my video in 1080 to repost it later on other platforms.
I've found thread with ffmpeg and multiple livestreams simultaneously that allows also capturing in other format than streaming, but this solution seems very convoluted despite fact I've worked with command line for many years.

I started using FB for church livestreaming a year ago, and recording original 1080p and streaming to FB at 720p is what I do
I set my canvas to 1080p, and I record that. I then re-scale video for streaming. This means encoding 2 video streams
But I have a GTX 1660 Super and use NVENC, and my GPU utilization is around 12% so no worries

Right after I wrote this topic I found, that I can ignore FB streaming settings in "stream" tab. Then I stream 1080 but FB is grabbing only 720 while I'm recording 1080. I hope FB is not going to ban me or something. ;)

So, FB will accept 1080p from those in its level up program
Others had reported FB accepting 1080p signal then down-converting (this may cause extra processing delay.. ymmv)
I tried a few weeks ago and FB would NOT accept a 1080p signal from me.
so, just be aware that you might try a 1080p stream to FB one future day and it NOT work.
