I capture live video and then edit up to 8 hours of raw video a day M-F and maybe if I am lucky find 10 to 20 seconds of
video I consider worth keeping.
Saving and editing those "keepers" also takes time so yes it it very time consuming (at least a few hours a day)
I caputer a lot of live stuff with an add on for chrome called "STREAM RECORDER"
https://www.hlsloader.com/It works pretty good for me on most sites (not youtub) Unfortunatly most editing programs cost money and I do not knwo of any good free ones
Good luck to you on you journey
