I want to watch the film on my laptop on Youtube, which one do I have to buy?
HD is always the best choice. The download takes longer, but the video is qualitatively better. Watch a YT video in 360p, that should be SD.
In my view, clearly HD, because HD has 1280 × 720 pixels or in FullHD 1920 × 1080 pixels as a resolution and SD only 720 × 576 pixels.
On the laptop you can see that relatively clearly. SD quality would only be practical for cell phones, as it takes up less storage space than HD or Full HD
You only choose the resolution, nothing else.
Does it have to be the best quality or is the standard quality of the past enough?
I see the film is from 2019, it should also be said that the SD has also improved because the films are already being filmed in higher resolution.
I usually watch SD today because I don't want to pay the surcharge xD
No, SD quality is 480p. YT is even behind when it is HD.
Understandable, but if the surcharge is small enough, I would do it. But on the phone, SD is a good choice if your storage is small (and you want to save money xD)
SD is sufficient.
As I understand it, hd somehow runs everywhere
