What a tracer should look like (before spazzing just look).

I'm getting personal because no matter what I show or tell you, you still don't listen.

Take a light source, say a laser pen light with a room full of smoke and point it towards something 5 ft away in a fixed position, so you can see the beam of light. Now have this light pattern repeat very rapidly. As this light source is switched on and off it will not matter one IOTA where you are standing or viewing the light. It will always be in a straight line UNLESS, you got hit by a freight train or decided to pull a few G's out of your butt while standing still. Your eye's WILL ALWAYS SEE THIS LINE AS STRAIGHT.

That is simple physics. You may see the line shorter or at a different angle depending on your viewing angle but viewing the trajectory of said moving object that produces the light trajectory will always be viewed in the in the same direction and trajectory that said object is traveling. (UNLESS as stated above)

If you can't understand that, then you need to take a remedial science class. Or you could quite simply fire and observe 1000's of rounds of tracer ammunition from fixed and high speed moving positions.

A Laser beam is physical, tracer streak is not, it's an effect. You cannot compare. As you already said, tracer rounds are dots not beams of light. Different.

You need to take the basic science class not me. If the tracer left a trail of smoke that would be straight no matter what becuse it actually exists. Tracer streak can only exist when it's being viewed. It's not 'there' all the time. It's a dot, or is it a circle or is it 2 circles on top of each other?

You are all over the place. Trajectory is an objects path in a 3d space and we're not dealing in 3d.

Have you ever seen the wobbly pencil trick where you take a real pencil and move it up and down in such a way that it appears to bend? It must be real magic to you...

Ok I am not reading all this crap but first off no matter who says it - anyone claiming to have RL experience take with a grain of salt, it is the internet. That being said what winny is saying is up to page 9 (stopped there) is correct to an extent. As for the 2d the problem there is that you have 2 eyes that the brain uses to create a 3d image, even though each eye can only see in "2d" individually.
The effect of the trail being left in your eye WOULD occur if you stared at it/focued on it, it would "burn" an image into your retina (desensitizes or overloads certain receptors, cant remember the actual biology of it) just like staring at a lightbulb and then closing your eyes. But you would have to be focusing on the round for it to remain in your vision in that way.

Also wouldnt higher calibre rounds have a larger base and more area emitting light? I dont know (thats why I am asking lol).

looks like the MKI eyeball fps thing won't be explained... must be something selective being applied there - oh well

oh, oh.. that's right - sparklers aren't rounds tracers, they're sparklers

yesss, you've said it yourself - "when the camera is moving" you're seeing the same camera quirk that has tracers zig-zagging in guncam footage
