I wasn't impressed with the clarity of Soaring the last time I went. It's gotta be digital, right?
They should not only increase the resolution, they should increase the frame rate. That's partly the secret to why Captain Jack looks so realistic in that new ride at HS.
It's not digital, it's film. As I've been saying, it's taking time for digital projection to get up to snuff. It will be there later this year (if on time).
[Some over-simplification below...]
Increasing the frame rate is not generally a solution that is needed, either. On average, the human eye can't discern more than 30 frames per second. That's the frame rate of North American standard TV video (with new digital standards, it can vary somewhat), and film is typically 24 true fps (shutters - those spinning disks with the holes in them, multiply the "frame rate" two or three times, but it was of the same frame two or three times...but it tended to fool the eye as smoother motion.
Why 30 and 24? In North America, Alternating Current electricity is fed into houses, etc. at 60 cycles per second. NTSC TV (the old analog standard) actually projected 60 half-frames per second...one frame was the odd lines, and one frame was the even lines. It happened to be convenient to use the AC as a timing mechanism. In other countries where AC runs at 50Hz, the video full frame rate is 25fps (PAL and SECAM systems). New digital standards have adopted similar rates, but also have additional ones (like full 50/60fps "progressive" video, etc.)
For film, the reason is a bit less clear, but it happened to work out to be 18 inches of 35mm film per second.
The 48fps being tested by some films mainly reduces "motion blur", which you can see especially when there is fast motion and you look at an individual frame - the object moving is blurred. A faster frame rate reduces that blur, so can provide a crisper image in situations of motion.
That's why there are two different standards for HD resolution and frame rate in the US...1080i and 720p. 1080i is a higher resolution, which is generally desirable - but it is also an interlaced video at 30 full frames per second (also called 60i). But broadcasters that were sports heavy wanted smoother video, and pushed for a progressive 60 frames per second (60p), but the resolution had to be smaller to fit in the same bandwidth.
Response on The Hobbit's 48fps were mixed...I haven't seen it yet, but I think it was just that the sharpness threw people who are used to film. It's sort of like when I see an LED-lit HDTV, vs. my older fluorescent unit...it just looks different.
