Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Digital cinema is 2K - 2048 horizontally.

Digital source files from the camera and/or the animators can be either 2K or 4K, or occasionally HDTV 1K-ish and let's-hope-no-one-notices.

2K has the same optical resolution as 35mm, more or less.

I don't know what the resolution of Imax is.

The Wikipedia machine says that 35mm Academy format and Imax 70mm compares like this:

... and while searching for that, I saw somewhere online that IMAX Digital is 4K.

I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.

And it's perhaps worth mentioning that 4K is a vast amount of data - it's about 2.5TB for a 90 minute movie.

Uncompressed, the data rate is nearly 500MB/s.

2K is more manageable. You can do 2K editing on a fast home PC now.

File resolution and projection resolution are not the same.
