It's funny how often these videos are from a camera pointed at a monitor, instead of a direct digital copy. I assume extracting the actual file is logistically tricky due to both technical and bureaucratic reasons.
There was a direct video feed, but that was being transmitted to Australia (facing the Moon at the time), and it wasn't possible to patch that directly through to US-compatible video feeds. The first images that Nasa received were upside down. The ultimate video, broadcast live internationally, was from a camera pointed at the CRT / television image at Honeysuckle Creek, near Canbera, ACT, Australia.
I'm having trouble finding a full retelling of this though here's a story of Honeysuckle Creek's role and a bit about the TV image:

More on the technical aspects of the video feed, but without my "camera-on-a-TV-screen" bit: <https://yewtu.be/watch?v=tIogywOrv8s>
That is all.
(And to spoil the joke: the inverted image actually originated from the Goldstone station in Southern California, not Oz.)

And “aim it at the moon” hah yeah. The Dish looks cool! I hadn’t heard of it I will give it a watch.
It appears to be a 'dumb' (but accurate) weeding and seeding solar powered battery backed "runs all day and much of the night" platform.
I say dumb as the major feature seems to be highly accurate (sub inch) positioning ( I'm guessing on site grounded in GPS differential base station as an error broadcast | local reference ) with a taunt bright red bit of heavy string sprung out around the four corners .. ie no vision processing and a simple "detect tree or human" stop moving trip wire.
It'll seed, remember seed positions and "weed" (disturb soil) about the remembered seed position .. but I'm guessing it'll weed out planted seeds if there's an origin or axis positioning error in re-calibration.
Still, it's being used in several countries - the 58 minute weekly Landline program devotes 10 or 12 minutes to it and the name is given of the Queensland(?) Ag. Dept. officer who's trialing it out (along with other systems).
That'd be the main point of interest for you if you ever get to wanting to officially test your rig in Australia.
Landline is free to view in Australia - it's just yt-dlp.exe that-url-I-gave-above with an AU proxy .. I can always drop it or just the relevant transcript if want either the .MKV or .SRT
Or as we like to call our nations capital, Canberra.

Those DVR/NVR (including networked cameras) should be among the first things hackers should liberate from their proprietary firmware: they all use Linux but keep it tight closed and quite often phone home somewhere in China, officially to allow users connect via the phone app (another big security concern) to their cloud service, which also means the feed goes through there.
One can buy the board alone by searching for "dvr board" on aliexpress and other shops; they're cheap and could be repurposed for other interesting uses because of their fast ADCs for example.

Or just point the phone at the screen, record, click the share button and select YouTube or whatever.
This was true back in the CRT and cheap Sony camcorder days, and it is even more true in the wide viewing angle, high quality phone image sensor, and image stabilization days.
But nobody cares to take five extra seconds to get good framing, or reduce glare, or hold their damn phone steady, or match the damn aspect ratio!
It's infuriating how little people seem to care in general
(I'm probably way late in becoming aware of this. It still simultaneously 1) blew my mind, 2) annoyed me, and 3) terrified me.)
This is why HDCP enforcement may be the dumbest legal-technical mandate ever. https://en.m.wikipedia.org/wiki/High-bandwidth_Digital_Conte...
"Someone has a recording device they can point at a screen" is a low bar.
Indeed. Because of HDCP common use cases like splitting, converting or sending a video signal are unsupported or afterthoughts by most consumer devices, even when dealing with non-protected signals. Of course, the HDCP flag can be removed by some shady devices but these are not commonly available and are often poorly documented.
Of course they aren't called "HDCP strippers", but ever since the master key was leaked/cracked, many anonymous devices with HDMI inputs will strip HDCP.
