Various special effect cases of Experiment 3

One . Mask animation case , Deformed flame man ：

First we need to prepare three materials , Flame foreground video , Flame background video , Human figure pictures
① Import all the materials into the new compositing window , Press Human figure pictures 、 Flame foreground video , Flame background video The order of

② Now operate on the foreground video layer , Select the layer , Then adjust the timeline to 13 frame , Choose the pen tool , Draw a graphic on the foreground video , Also activate the key frame of the mask shape . Then put the playback header on the timeline , To adjust to 0s It's about , Press and hold the shortcut key ctrl+T, Zoom out the figure you just drew , A key frame is automatically generated .

③ Notice the most important step , Now select the mask in the target 1, Then the human figure drawn next belongs to this mask . Now turn the playback head to 3s It's about , Now draw the outline of the character with a pen （ Operate in the composition window ）, When you start sketching , The original shape will disappear . And the timeline of the mask shape will automatically generate a key frame .

④ After painting the figures , Press 0, You can see , The mask shape changes from small to large , And then gradually become a human form .

⑤ Finally, put the picture of the character in the flame foreground video , Behind the two layers of the flame background video .

Two . Metal word effect

1. Click on T Text tools , Enter text directly in the window .（ The following operations are performed on the text layer ）

2. Metal characters mainly add three effects to the text ：① effect — Generate — The gradient ② effect — perspective — Inclined plane Alpha③ Color correction — curve

3. In the special effects console , Adjust the corresponding parameters for each effect .
① Set the start and end positions of the gradient , Adjust it to just cover the text （ Free play to adjust other parameters , Such as color ）
② You can activate the slope Alpha The key frame of the illumination angle , Add multiple keyframes , The illumination angle of each key frame is set to different , In this way, different angles and colors can be produced .（ Over time ）
③ Adjust the curve shape of color correction , Can make the color of text produce the effect of fluid

3. Keying series （ Basic steps , Select the material layer — Click effect — Click keying — Select the corresponding keying effect ）
（1） Differential mask keying ： Three materials , Target layer 、 Background layer 、 background , The target layer is mostly similar to the background layer , Then add the difference key to the target layer , Modify parameters in the special effects window , Change the difference layer to the background layer .
Then the target layer will subtract the background layer , The different elements between them will be left . Then in the timeline window , Make the background layer invisible .
Adding keys to the tolerance can cause the character to fade away , Or a gradual effect .

（2） Brightness keying ： effect ： According to different brightness matting , There are three kinds of effects: bright parts are pulled out 、 The dark part pulls out 、 Dig out similar areas 、 Pick out the non similar areas , Adjust the threshold value to cut the picture

（3） Internal and external keys ： First, add two masks to the material layer with a pen , A mask for the inner contour , A mask for the outer contour . Then add internal and external key effects to the material , The foreground is set to mask one , The background is set to mask two . Dissatisfied with the foreground or background , You can add new masks , Then modify the mask corresponding to the background or foreground
（4） Color key ： Great color difference available

3、 ... and . Text path effect

① Input text , Select the text , Trace the outline of the earth with a pen , Automatically generate a mask , then , Modify the transformation properties of the text , Around the x Shaft rotation 75°. Click text properties , Set the text path to mask 1.
② Add a key to the start blank attribute , Make the text rotate around the earth .

Four . Fragment effect

Input text , Click effect - Simulation - debris , You can modify the shape and size of the fragment 、 Blasting range 、 Blasting location （ General adjustment focus 1 that will do ）、 Direction , Add corresponding keys to animate . Some screenshots are as follows ：
