Genlock is a sync signal for video that lets all devices march in lock step. (e.g. they will all be creating video frames at the same moment in time) There are two main types, blackburst and trilevel. I would generally use blackburst by default, and only switch to trilevel if you encounter issues.

I know how genlock works in principle. You have a sync generator and you lock everything together which keeps everything nice and together when you are cutting. How does this work in practice though?
Genlock helps latency by timing the frames together so they don’t drift, and so they don’t need to be re-timed and synchronized with the rest of the system. So, latency can be cumulative between. Hdmi to sdi, and sdi to switcher and so on.
How does genlock improve the quality of footage captured by multiple cameras during a single production? Genlock improves the quality of footage by ensuring that all cameras are synchronized, preventing issues like image tearing or inconsistent frame rates.
Genlock is a technique used in video production that synchronizes the frame rate of multiple cameras or video sources to a master clock signal. This synchronization ensures that all connected devices operate in unison, eliminating issues like frame drift and allowing for seamless transitions and multi-camera setups.
How does syncing work? Important, that only the outputs of all the connected hardware will be synchronized. Better said: the output of the upcoming frame will be happening at the exact same time for all hardware. The sync/genlock signal is coming from a Sync Generator (this is a separate hardware) and is connected to all hardware with an SDI cable.
