Lin Dan rubbed the ball in slow motionWhen rubbing the ball with the backhand, the basic position was to place the left foot in front and the right foot behind. When preparing, the center of gravity of the body was slightly forward. In terms of movement essentials, the elbow joint in front of the body played a supporting role to stabilize the arm. The upper arm basically did not exert force, and the forearm was in front of the body and above the table. When taking the racket, the forearm should be close to the body and slightly raised to the upper left. When adjusting the racket face, the wrist should not be rotated greatly. It should mainly rely on the forearm to rotate inward and outward to adjust the angle. The wrist should be relaxed, and the racket and forearm should not be completely straight. When rubbing the ball, adjust the racquet face according to the rotation and arc of the incoming ball. If the incoming ball's backspin is not strong and the arc is high, the racquet face will stand up slightly when the racquet is pulled. During the rubbing process, swing the racquet to the right, lower, and front. Relax the wrist and follow the forearm to the right, lower, and front to shake the middle and lower part of the ball. During practice, you can improve your backhand ball rubbing technique by retracting the racquet practice (self-throw to feel the arm and wrist swing, retracting the wrist when the racquet is pulled in), adjusting the racquet face (relax the hand to change the angle of the racquet face), rubbing the descending period (stand near the platform, rub the ball on the stage after the ball is released), lowering the center of gravity, etc. Pay attention to standing further away during practice and control the arc. When the ball arc is high, the rubbing force will be slightly lower. The racket face will be soft and not crooked. The center of gravity will be lowered. It is better to wait for the ball to drop before rubbing the ball. It is best not to use the serve machine to practice because the serve machine has a dead arc and fast rhythm. The coach will send the ball arc more gently, which is more conducive to controlling the rhythm.

Soft ball, zero foundation, slow motionThe following are the key points to learn the zero-foundation slow motion of the softball:
1. ** Preparing posture **: Stand up naturally with both feet shoulder width. He held the ball in his left hand and the racket in his right hand. He tilted the racket slightly and bent his knees slightly to maintain his balance.
2. ** Guiding action (Take the right hand as an example)**:
- Throw the ball up with your left hand and slow down so that you can accurately grasp the rhythm.
- Hold the racket with your right hand forward to meet the ball. Pay attention to the contact point between the racket and the ball.
3. ** Arc Induction **:
- After the ball was placed into the racket, he slowly began to make an arc.
- During this process, he had to experience the feeling of the ball moving on the racket by inertia. The movements of his arms had to be stable and coherent, and he had to control the trajectory of the ball.
4. ** Basic Movement: Left and Right Swinging (Slow Movement Version)**:
- The racket swung from the right to the left, and then from the left back to the right. The entire path was like a pendulum.
- The key points of the movement were that, regardless of whether the racket was on the right or left, the tip of the racket must be forward; when swinging, the shoulders should not be raised too high; when swinging to the left, the waist should be turned so that the shoulder axis rushed to the middle. Each movement should be changed slowly to experience the coordination of various parts of the body.
5. ** Basic Movement: Swinging Around (slow motion version)**:
- On top of the left and right swinging movements, he added footwork training.
- When he opened his left foot and right foot, he had to lift his heel before opening his left foot. When walking, one's hands had to circle around the body, drawing a clockwise or counterclockwise circle in front of the body. The process of drawing a circle had to be slow, and the tip of the racket had to rush forward when the circle was drawn.
6. ** Practicing Basic Elements (Experience in Slow Movement)**:
- "Return: When the soft ball comes over, the racket will slowly go up to receive the ball. Feel the timing and range of action to accurately receive the ball.
- Guide: After the ball enters the racket, slowly move in an arc. Experience the feeling of the body driving the arm, the arm driving the racket, and the ball moving in the racket.
- Throw: After completing the action inside the racket, slowly throw the ball out of the racket. Pay attention to controlling the direction and strength of the throw.
Reverse slow-motion videoIf you want to create a reverse slow-motion video, you can use the following software:
- Da Vinci: This is a professional software that combines video editing and audio post-production. First, he opened the software to import the video. After selecting the video, he clicked on [Change Film Speed], then checked [Reverse Speed] and adjusted the speed to a negative number to play the video in reverse. Then, he used the software's function to set the slow-motion effect.
- Swift Video Converters: Professional Media Processing Service software. Enter the software and choose [Video Rewind]. After import the video that needs to be played in reverse, click [Set Rewind] on the right side. Check [Video Rewind] and adjust the sound in the video (support retaining the original sound, removing the original sound, and playing the original sound in reverse, etc.). Then choose [OK], and finally click [Deal with All]. Then, set the slow motion effect.
- [Video Editor: A video editor with a wide range of uses.] He would import the video that needed to be played in reverse and add it to the timeline. First, he would select the [Reverse] function to play it in reverse. Then, he would set the slow motion through the speed curve and other functions. For example, after turning around, he would add a point at the position where he wanted to slow motion and adjust the speed of the point to achieve the slow motion effect.
- Pocket Video Converters: An efficient video editing software. The video playback function that it supported was used to reverse the video, and then the software function was used to set the slow-motion effect.

Slow motion camera tutorialThe tutorial for shooting slow motion with different equipment is as follows:
1. ** Some Xiaomi phones **: Turn on the camera, click on the top right corner to enter the camera settings, customize the camera function layout, and press and drag the icon to adjust the layout to achieve slow motion shooting.
2. ** Osmo Pocket Pocket Cloud Platform camera, Osmo Action camera, Osmo Mobile phone cloud platform 3, Dajiang drone Mavic Mavic 2 and Mavic Air**: connect the device to the phone, and then operate it in the DJI Mimo App interface to take a slow motion effect.
3. ** Using AI (Take Huawe-related technology as an example)**:
- First, the frame information and event information captured by the two cameras were sent to the warping and synthesizing modules. The warping module used the U-shaped network to convert the motion into optical flow representation, and then converted the events into real frames; the synthesis module used the U-shaped network to place the events between two frames and directly generate a new possible frame for each event.
- Since the synthesized video might have noise, the third module would use the new information in the second intercept synthesis module to refine the first module, which was to extract the most valuable information from the two generated frames of the same event and perform warping optimization (again using the U-net network to generate the third frame version of the event).
- Finally, these three candidate frames were input into an attention-based average module, which used the best part of the three frame representation to form the final frame. Repeating this process for all the events provided by the event camera would produce the final desired result.
4. ** Computer (using PR or FCPX software)**: import the captured footage into the software and change the speed of a certain area of the footage to achieve a slow-motion effect.
5. ** General camera equipment **:
- ** Device Selection **:
- ** Cameras **: Many modern DSLR cameras and mirrorless cameras support high frame rate shooting, such as the SonyA7S series and Canon Eos R series, which can shoot 1080p or 4K video at high frame rates. Professional cameras such as the SonyFS7 and the Red series can provide higher frame rates and better picture quality, but the price is relatively higher.
- ** Lenses **: Fast lenses can perform better in low-light environments, wide-angle lenses are suitable for capturing vast scenes, and telephoto lenses are suitable for capturing distant details.
- ** Tripod and Stabilizer **: When shooting in slow motion, stability is very important. Using a tripod can ensure the stability of the camera and avoid blurring the picture due to shaking.
- ** Principle **: By shooting a video at a high frame rate (such as 60fps, 120fps, 240fps, or even higher, the standard frame rate for movies is 24 frames per second), and then playing it back at a normal speed during playback, time can be slowed down to capture more detailed movements.

Swords around flowers slow motionAs for the description of the slow motion of the sword around the flower, the arm of the inner wrist flower was flat, and the thumb and index finger were closed at the hilt. The first movement was to lay the sword flat, the second movement was to turn the arm, and the third movement was to turn the sword around. When the sword was falling down, don't grab the hand and buckle it. You should use the inertia of the sword to turn the hand. The little finger will gradually go down by itself. When the sword is falling down, give a little strength to the wrist and turn it around. He controlled his wrist, tried not to move his arm, and controlled the sword between his thumb and forefinger. The sword flower had to be close to him.
