...Moving the jib cars forwards will put more tension on the leech and may stop it from flapping. With your car set so far aft all of the tension is on the foot and little of it is on the leech. Most sails will also have a line in the leech that can be used to remove leech flutter. You need to be careful not to get it too tight because that will hook the leech of the sail.
As a general rule of thumb you should start with the jib sheet coming at an angle that would bisect the luff of the jib. That will work in moderate conditions, in high winds you'd move it aft (which flattens the lower portion of the sail and adds twist to depower the sail) and in low winds you'd move it forward (which makes the sail fuller and adds power)....
I agree with the above suggestions.
In your video it appears the winds were at least 12 - 15 and I would definitely suggest you need to move the jib cars forward quite some distance to get a lot of the flutter out of the leach.
Looking closely at your jib in the video it "appears" you have the leach line mentioned above. Try tightening it slightly to remove any remaining flutter.
The leach line is a small line running down the back edge of your sail (the leach) and there should be a small plastic cleat that will hold the line after you adjust it. In the video it appears the cleat and line are about 12 - 18" up from the foot of the sail. It appears about a foot of the line is blowing freely in the wind.
