What if the Zapruder film is authentic?

I'd really like to see them, because I can only see a red mist in front of Jackie's collar area in frame 313 on the youtube I'm looking at.

Ah yes the red mist in Z-313, which is suspiciously absent in Z-314, which underscores the obvious fact that those frame were altered.

Assassination Science houses my favorite evidence of the tampering. And the disappearance of the red mist in a fraction of a second is a clincher:

No way that could happen in real life, or real death. That blood should have been visible for many frames after 313.

I attached frames 313, 314, 315. I also attached the blood graph. All of the pix are from Assassination Science. Here is the accompanying text from Assassination Science:

"On the previous page we looked at David Lifton’s discovery, back in the 1960s, that the wound to JFK’s head shown on the Zapruder film is a fake. More recently, scientists have discovered that there is something else about the shot to JFK’s head on the forged film that is fake—and can be proved to be fake: the spray of blood that appears at the moment he is shot.
Film experts had noted that the “blood spray” in Frame 313 looks like it has been “painted on” and then exposed onto a genuine strip of film:

But what tells us that this “blood” is fake is the fact that it disappears into thin air!
If it was real, the “blood” should spread out in the frames after Frame 313, and then land on people or objects in the car. But within a couple of frames, it disappears altogether:

Scientists were able to test whether the blood really did disappear. They analyzed the film frames around the shot to JFK’s head:

Every color picture can be broken down into red, green, and blue light. (If you look closely at your TV, you can see the little red, green and blue lights!) The total red, green, and blue light in each of the frames was measured by computer, and put onto a graph:

The graphs show that the “spray” disappears within three frames, or one-sixth of a second. This can’t happen!"
