You know digital videos have resolution such as 4K.
How about Films?
Most movies were shot on 35 mm film from the early time of cinema to 2000s.
They also have a technical "resolution," it's just measured and expressed differently...as a measure of the ability to capture subject detail.
The resolution of the film system (lens and film) would be measured by photographing a suitable resolution target (which would typically be bars or lines of decreasing width and separation precisely printed to a metal surface) at a specific distance.
The expression would be that the system "resolved n lines or bars per millimeter."
The factors of the system, the lens and the film, can be measured for their separate abilities to resolve subject detail, but the resolution of the lens/film system is always less than the maximum resolution of either factor separately.

However there is no pixels on films.
Is it something else that counts instead of pixels?
