I see. thanks for the heads up.
I agree that the unenhanced Costella frames aren't very clear but they do have value. There are sources that show enhanced frames. One of the best is David Von Pein's website which contains a wide variety of material. One of the best is his examination of the Single Bullet Theory. He presents enlarged and stabilized Zapruder frames at the critical time when the single bullet struck. You might as well know that David, like me, believes that Oswald acted alone, but you can decide for yourself how valid his evidence and beliefs are. As I told you initially, don't accept anybody's arguments at face value. Verify the validity of their arguments and evidence before rendering a judgement.
