I think it's understandable that this would be confusing. Hopefully we can get it sorted out here.
Exhibitor-Branded Premium Large Formats
Regal's RPX is what the industry refers to as a "premium large format" brand. It is intended to provide an assurance that you'll be watching the movie in the largest house, with the biggest screen at the particular ...
Set it on fire
Perhaps from a lit cigarette.
Old film stock was nitrate based...
Nitrate film base was the first transparent flexible plasticized base commercially available, thanks to celluloid developments by John Carbutt, Hannibal Goodwin, and Eastman Kodak in the 1880s. Eastman was the first to manufacture this for public sale, in 1889. Unfortunately, ...
I have been a projectionist for over 20 years, so hopefully can help to answer your question. You don't say what period you are setting your story in as that has a bit of an impact on exactly how the damage might happen.
Nitrate film would have caught fire, from getting stuck in the gate of the projector and the heat from the Carbon Arcs. There were cut ...
I'll get to a nifty solution that meets one of your examples a bit better towards the end, but in the meantime....
There are likely several reasons (this hasn't been done very well until recently):
They would still require separate hardware to be projected on a separate screen bellow the main screen. While it may not be as big a deal now that we've gone all ...
This thread on Reddit somewhat explains the effect:
A very clever use of the camera frame rate, rolling shutter, and a
CMOS censor, combined with timed projection. You would only be able to
see this in camera, not live.
Another user adds:
The laser fixtures are KVANT Spectrums.
And I’m not an expert on camera work but I do work electrics for ...
Slate did a good breakdown on resolutions. To directly answer your question:
IMAX Laser = 4k horizontal resolution, 1.43:1 aspect
IMAX Xenon = 2K horizontal resolution, 1.9:1 aspect
IMAX 70mm - 16k horizontal resolution, 1.43:1 aspect
70mm NON-IMAX= 12k horizontal resolution, 2.20:1 aspect
So the answer is 70mm non-IMAX over non-70mm IMAX ...
Analogue projectors don't have a resolution. It's entirely dependent on the size and grain of the film. In general, raw analogue film has a much higher "resolution" than digital formats.
[IMAX digital] has a maximum perceived resolution of 2.9K, compared to traditional IMAX 70mm projection, which has an estimated resolution of 12K.
