In a movie I'm sure they will look OK (I hope!) |
You are prefectly right (writing at home already...)
The leight of tracer depending of the sutter speed. As shorter shutter speed - shorter tracer fixed on the image.
If we will have the speed, say for example, 1/100000 sec, then we will see the light of tracer like the exhaust of small jet engine on a fixed image. But in reality the inertion of the human eye/brain is close to shutter speed of 1/125 sec fixing image.
In the beginning we have variable leight of tracers (Roman Denisking did right calculation and programmed it) depending of frame rate (which is really almost the same like shutter speed of camera, iof the frame rate is constant.)... But when we have slow frame rate of the game... the tracers had too great leight.
So now they are fixed as a middle possible for all realistic frame rates and human eye inertion.
You may see we really did the good job of searching and programming for such things...
To all:
About Z - tracers... when B-17II was sent.... I told already it is incorrect. Then told it I think more than 4 times later explaing slow speed sutter of camera and movement of the plane and camera relatively the optical axis that was on anoither place on previous frame.... Should be understandable even from this short description.
To all:
About sync. Shots of wing's guns are asynchronized. Be sure. With the serios research for the time between barrels it would be possible. including differences such as mechnical, explposions, etc... including electrical sync for the shot
when it will be neccessary to use....
