I am researching an application where I need to record two 4K@30 video sources as well as encode a single HD@30 video. The video is a warped product from the two sources.
That gives me a need for three encoders, and NX is limited by two. I am therefore researching a workaround.
My question is therefore. Would the following scheme work:
The NX capacity is two 4K videos at 30 fps. Each signal is 3840x2160. That gives me a pixel budget of 238402160 pixels.
I would spend 1/8 of the bandwidth on encoding the HD signal, leaving me with (7/8)of the budget for stacking the two images. That means that if I can crop the source images from 3840x2160 to 3840x1890 I should keep the budget.
Does the NX support such schemes or is there something else I should be aware of?
I would hate to be forced to add an external PCI-e encoder to solve the job.
