Try not to record raw but to transcode on the fly or make use of camera's

Do you have a reference signal? ...[snip]...
As far as refresh rate value goes, make sure that both camera and capturing
adapter support desired one.
Capture long and prosper!
P>S. Oh sorry I just read top of the house part. I guess 100m is enough.
Forget about clock and use SDI over coax.
This looks like off topic isn't it ?
Thank you, Dragan. Off-topic or not, it's very helpful suggestions as I
report to my boss about building the capture system.
Actually, it makes me inclined to tell my boss to hire a proper digital
video expert to design the capture system, or to pay for the proprietary
capture system. I'm just a software engineer. I can figure out these
video factors, but maybe my boss doesn't want to pay me to learn all of
that.
