They're light, and convey very little actual information, most of that incidentally.
British Pathe, especially during and after WWII, was unabashadly propagandistic. It produced short newsreels for popular audiences to view before the main feature in theatres. Themes were pro-British, pro-Empire, and pro-Industry. Technical content was minimal.
At its best, YouTube offers markedly better. One example off the top of my head is the Engineer Guy channel, with numerous phenomenally good, non-self-promotional videos. His on the RMS Titanic, the British Airship R.101, on the design (and manufacture) of the aluminium can, and his re-enactment of Michael Faraday's "Natural History of the Candle" (proving that the Brits can actually create high-quality educational content) are all excellent, and I've watched all of them.
Bill Hammack has his own biases, occasional blind spots, and does occasionally promote (he wrote a book on R.101, as he'll happily tell you, and does). But he produces excellent work, first and foremost.
