Hi,
I cannot really give yu an answer about how the cams work and which one might be more suitable in regards of all the details you might conisder.
But due to we are searching content here:
https://gfy.com/gfy-content-market/11...broadcast.html
in 4:2:2 and in 25 FPS ( PAL) I can tell you that this is material really asked for from now on for broadcast (you can always break down quality later for web), and many did miss to work in these specs.
So, its rarer to find these than most other specs of materials.
So, I think 4:2:2 is secure for the future.
