Yes, but you're forgetting editing wasn't digital/digitized. You would copy from one tape to another, so a degradation issue. It's not the TV's capabilities, but if you started with higher quality you would get less overall degradation. I took film classes in TSOA at NYT back in 1982, and one class was film production and the other was lugging around a huge deck and camera in Betamax and then going back to a tape-to-tape transfer editing deck.

Well, sure. My point is, as a consumer product, betamax did not deliver on its promise to the consumer that bought it. It's really not important at which stage of content production and distribution the promises got lost (and I think you might be underappreciating 'most people's TV set was pretty meh', especially after the components had some life on them). It was sold to my amateur audiophile dad (yes, we had a reel-to-reel) as 'world changing video', and it wasn't, certainly not at the price point. I think the obvious superiority at the content production phase is testified to by the crazy longevity of BM in that niche, but since we couldn't really see that in our house, we (and almost everyone) bought the VHS.
