As has already been stated, but I will reiterate, nothing changed about my initial point.
Just trying to calibrate it. Consider the following scenarios.
a. It's 2092 and a 240 FPS version of Star Wars is released. Does the ghost of George Lucas care? I don't think so.
b. Ridley Scott finds out I'm watching Gladiator on a TV the auto-interpolates frame to pump up the frame rate. Does he care? I don't think so. And if he does, I don't.
c. Guillermo de Toro is approached by the studio with a special director's cut which will include an upped frame-rate as one of the options. Do you think he refuses? I don't know. I don't see why he would as a matter of presumption.
d. Chris Nolan finds out in 2035 that Tenet has a planned re-release. The marketing nerds approach him because they want to up the FPS for modern audiences. Does he "welcome" this change? I think so.
e. It's 2022. Will Quentin Tarantino "demand" that Pulp Fiction be released with more frames? In this case, definitely not.
In many of these scenarios, I think the directors would welcome the change or not care that much. And as we head into the future I think the old school celluloid ascetics will die off, making these changes much less controversial and much more natural. Maybe we're not there yet? OK. But I don't doubt this is where we're heading.
As I already explained, war footage isn't art. What are you not understanding here?
Quite a bit, actually. It is MORE of a sin to monkey around with actual historical footage of significant events. Don't make that tank a color selected by an algorithm. Don't add CGI elements into the frame to enhance the drama. Preserve the original and make sure the experience of the viewing is equivalent to the light which would have entered the camera, as close as we can get what the eye would have seen in the moment. And upping the frame rate does not mangle history in this sense (where colorization does).
