I've just begun messing around uploading experimental videos on Youtube, all of mine are rather crude at this point, but I am getting my feet wet so to speak. I was shopping for a video recorder about 2 and half years ago, and being able to mount on a tripod and hold comfortably with one hand, auto as well as manual focusing, HD formats, shooting in low-light, recording memory at least two hours, and being able to mount on a flatcar were my up-front criteria. I ended up with a Sony Handycam - FDR-AC33. The memory feature is via cards - small disks about the size of a large stamp. I like the camera, however it's a little pudgy - ostensibly due to the wide-angle lens and all the features, and if finances allow I'll eventually get a narrower camcorder just for flatcar, and use the FDR for tripod and trackside shots. I briefly messed around with Sony's free editing software, but YouTube has an even easier editing feature. Strictly amateur stuff I am sure.
Despite that my camera records in HD (either 1080 or 4k I think), the "free" YouTube channel that I have defaults to uploading standard format - 480 - which is okay for messing around. I suppose there's a charge if you want to upload videos recorded in HD, due to data size. Thus the video below is shown in standard format...I tell you though, once I plug my camera into my HD tv, and hit play in 1080 format the results are awesome. The video below demonstrates the "pudgy" ramifications as the camera rubs the rock wall. This is how I learn: by doing All of this, like building a layout, train maintenance, takes time, which is of short supply as I am still working my backside off earning a living, not to mention household and yard chores.
