The vidoe above, which you selected to show I was wrong, actually proves my doubt. Please look at the following pictures captured from the video.

In either picture, the tracer "light rod" has both varying brightness and varying diametre (thickness) from head to tail. The fact is too clear to be overlooked.

More can be captured from the video but these two are enough. In addition, the absence of homogeneity (eg, in terms of brightness) along a tracer "light rod" in the air may not be visible at night, because all parts of it are too bright in darkness, so that the camera or the human eye will most probably register all parts as "maximum brightness".

Some people may have also noticed that the distance between the tracer and the camera can play a part in influencing what the tracer looks like in the film - which is quite natural, since the nearer you are, the more details you get.

As I said, what tracers look like is a complex subject.

You two "proof" photos are only showing that the tracer has just lit as it is coming out of the barrel and takes a foot or two to reach full brightness, nothing more.
Take a look at the tracers after they reach full brightness. Their width is the same down the length of the trace.
On film and in the human eye the brighter a small object becomes, the bigger, or wider in this case, it appears.
As far as their appearance being a complex subject, I agree as much as saying that a simulated tracer must be dynamic to be realistic. It must be able to have varying lengths depending on apparent speed to the observer.
This is what Ilya is talking about when he says that the tracers are perfect as this is taken into account.

Took the words right out of my mouth.

Another thing that people should take into accound when looking at modern tracers used by the military (in the past 30 years) is that they have a delayed start, so that they will go a hundred yards or more before lighting. This is to keep the operator from being blinded in low-light or night situations and it also has the benefit of not giving the enemy a perfect line to where the gunfire is coming from.

Also that is .45ACP, quite possibly the slowest tracer ammo avaliable in the world (do muskets have tracers?). So it is not going to behave exactly like something traveling 3-4x faster than it.

So much BS and nitpicking over an effect which I am SURE the dev team have got right, geez louise :rolleyes:

You guys must have little to do with your time if you can spend so much time and effort endlessly arguing about this, god help us all when the game is finally released and you start arguing about the size of fields/haystacks/trees etc ad infinitum :rolleyes:

You may be more right than you know. I'm retired and have plenty of time for this:)
It actually entertains me.
I was only trying to clarify some misconceptions ;)

Taking a foot or two to reach full brightness? Maybe, and maybe not.

If you still say this one bullet has just lit out there, then the "just lit" part is even brighter.

If it is argued that distance is the reason why the nearer end is brighter than the farther end, then this reasoning applies to all vidoes where each tracer segment has homogeneous brightness and width from beginnnig to end. In other words, when a vidoe show that the tracer segments have the same brightness and width down their length, that is because "distance" intervened, and actually they are not homogeneous.

You do realise that the "lit part" is the only part making that light, right? It's not a glowing tube with a burning end, it's an illusion created by your eye and brain.

Now this is where the camera and eye start to differ, and where compression, framerate and lens quality fall short.

The tracers in Cliffs of Dover are accurate. This is coming from the people who made them, and the people who have actually seen and fired real tracers in real life!

*idiot hat put on*

If it ain't on youtube it ain't real.

Having had some ideas on tracer I see this thread with the same thoughts of naked eye v camera effect. see my argument at http://forum.1cpublishing.eu/showthread.php?t=32624 and what may be a PC monitor limitation .

I certainly cannot understand how a tracer round can flash on and off so giving us a dashed line, and it cant be seen as one long streak of light, how can it still glow at 0.1inch from barrel and be glowing 250 yds from barrel, in reality that is, but it could on a slow fps film camera, where the film frame was exposed for the length of time it took to do 250 yds.

The arguments put fwd as videos are null and void as they are how cameras capture it. They illustrate my very reasoning.

A video here showing what I feel we would see in reality http://www.youtube.com/watch?v=bx5aR...layer_embedded

That looks exactly like what I see in CoD
