I work for the railroad and this is incorrect. The big fight this contract was for actual sick leave. As of right now if I was to get sick and call in I'd potentially lose an entire weeks worth of pay for taking that one day off (our pay system is complicated) and have a mark on my attendance. Most class ones only allow three hits before you are let go. Some take this a step further and make weekends and holidays count as two strikes. Since we work on call 24 hours 6 days a week with no guarantee of actually being home for your day off doing things as simple as scheduling a doctors appointment becomes a nightmare.
What happened in December was congress removed the sick leave portion and made it a separate bill. H.J. Res. 100 passed to block us from striking while the bill for sick leave H.Con.Res.119 failed at the senate.
You will get leagues better picture quality using a camlink/capture card and a camera with clean HDMI out. A gopro is a good budget option but a used DLSR or mirrorless camera is going to be the best. Some DSLR and mirrorless cameras support video out over usb so you don't even need a capture card. Here's a guide on getting it to work on Linux with a camera capability list inside the guide. If you do want to go the capture card route I hear elgato's camlink works in Linux.
