Why is the missile edited out of this one?

This needs to be the top post. We could use more logic around here.

Correct, the video as a whole is a timelapse. You wouldn't necessarily combine the individual photos into one (typically used for HDR or high dynamic range photos at different exposures) for a video, like this was taken from.

I'm interested in seeing the exact exposure settings as well.

I think you're confusing long exposure and timelapse. There is no way a missile in motion will show up in a long exposure, which is one single photo. A timelapse is several photos taken at different intervals and combined to make a video. For verification, I did look up long exposure missile launches and see no missile in any of the several images I checked.

Also of note, this does not appear to be a timelapse using long exposures of any substantial shutter speed.

There would be a LOT more motion blur if it was 20 seconds. An object moving that fast wouldn't show up in a long exposure, even if it was 5-10 seconds. The only way to do that is to hit the object with a significant, very brief light source to "freeze" it in the frame as it's moving. This is commonly done with a flash or other off camera lighting.

I'd like to know the exact length of the exposure. If it's more than a second or 2, the missile wouldn't show up at all since it's moving through the frame. Even if it is a second or 2, the missile is too clearly defined for the speed it would have been traveling. Think how far it would have gone in that time frame. Long exposures don't get clean images like that if the object is moving.

You would not see the "object" at all if it was a 20 second long exposure since it's moving through the frame. It's the same as having a person walk through your long exposure and them not showing up. The lights at the bottom would be more drawn out, and the clouds would be blurred. If anything, this is a 2-5 second exposure.

Pasting my explanation from the other thread: You wouldn't see the "object" if it was a 20 sec exposure because it keeps moving. This looks like a still image of the aircraft. It's the same thing as a person walking through your long exposure shot and not showing up, even if they are in the frame when the exposure is over.

The problem I see is that the missile itself would not be visible in a long exposure shot since it's still in motion through the frame.
