(Video included) Ronaldinho's 4 goals outside the penalty area did not hit the ground. Is it true or false?

False, there are three evidences:

One; Doubtful point: The picture effect is too rough.

Professional opinion: Continuously shooting at the beam and bouncing back is an effect that can only be achieved through post-production.

Interpretation: The video picture is a complete long shot without any cut points and cannot be the result of processing. But after watching it a few more times, the video showed its flaws.

Technique 1: Rough images in post-production. Generally speaking, the picture effect taken by a home camera is relatively poor, and the picture will be rough. It is unlikely that a home camera was used for Ronaldinho's online video. The most likely possibility is that it was shot with professional photography equipment and then used in post-production to make the picture relatively rough.

Technique 2: Use "keying" technology. From the online video, it can be seen that Ronaldo did the same action four times on the court, and each time he hit the crossbar and bounced back to his feet. This is most likely due to the use of "keying" technology in photography. The foreign "image keying" technology is generally called "green keying". That is, before shooting, the technicians design a series of actions such as Ronaldo's random shooting and bumping the ball on the court, as well as the trajectory of the shot, and even Precisely how many meters traveled. Every time a shot is shot, it is shot once, and then the football, other players on the field, scenery, etc. are added to the picture one by one during post-production.

Two: Doubtful points: All four shots hit the crossbar, and the rebound directions were surprisingly consistent.

Professional opinion: The contact area of ??a round object is small, and it is unlikely that it will continuously shoot towards the beam.

Interpretation: Even if a machine were designed, it would be difficult to achieve the accuracy of Ronaldinho hitting the crossbar four times in a row in the video, let alone an ordinary football player. Ordinary people's ankles are round, and footballs and crossbars are also round. To a certain extent, this increases the difficulty of contact between them. Round objects limit the contact area between the football and the crossbar, reducing the contact area between the two, thereby increasing the difficulty of contact.

After Ronaldo shot many times in the video, the football basically bounced back to Ronaldo's position. In a normal football match, the chance of the football hitting the crossbar is low, let alone Ronaldo four times in a row, and the direction of the football after it bounces off the crossbar should be different. If the football hits the crossbar and bounces back to the same point, it is possible that the force of the kick, the position of the ball and a series of external factors must be exactly the same.

Three: Doubtful point: The football returns to the same direction continuously.

Pro tip: The odds of a football bouncing back in the same direction four times in a row are slim to none.

Interpretation: When a football player shoots a goal, the football will return in the same direction only if the direction of the football's flight is perpendicular to the incident surface when the football and the crossbar are in contact. However, it is difficult for ordinary people to achieve the same results four times in a row. In addition to some external factors such as wind and foot strength, there are many complex factors. There are many "points" on the round football, not just one point that touches the foot and crossbar as everyone thinks. The many points on the football cause the ball's direction to change ever-changing when it touches the object. It is extremely difficult to control the contact point, making it difficult to "return to the original path" four times.

It seems that this controversy can be ended. Nike seems to have really paid Ronaldinho a lot of money and forced him to tell lies
