Higher Speed

I am very excited about Douglas Trumbull's Showscan. Can we please have an article about it. His process is so simple: increase the speed and you get rid of strobing and undesirable blue in action sequences. I have seen Imax and it is impressive but the strobing problem is amplified and can cause headaches.

I have observed that 8mm at high speeds of 62 fps gives the impression of "looking out a window." Techniscope at 48 fps could be a vast improvement using the same amount of film stock. Only the movement in the projectors would need to be replaced. At higher speeds grain drops out, so 48 fps 2 perf would be no grainier than 4 perf full frame projections.

New standards of quality are needed in the film industry. Let's resurrect Techniscope and soup it up to 48 fps!
