After effect Study Notes (1)

1. to import an image sequence as a video, you only need to check the sequence items shown in the import file window.

2. interpreting materials (defining materials)

Select Material-file-definition material: In this window, you can select the alpha channel switch for materials with alpha channels (recording transparent information. You can also choose to enable or disable a field.

3. Dragging materials directly into the merging window is the same effect as dragging the materials into the timeline.

4. to precisely locate the time axis pointer, you can click the yellow time code and directly enter a value. You do not need to add a colon to the input. For example, the 200 table type is 2 seconds, and 211 indicates 2 seconds and 11 frames, 2211 indicates 22 seconds and 11 frames, 22211 indicates 2 minutes 22 seconds and 11 frames, and 245 indicates 3 seconds and 20 frames (because 25 frames are in one second)

5. When the Key Frame Switch of the layer is enabled (that is, the stopwatch in front), you only need to change the state of the layer to insert the key frame on the timeline, as long as the key frames are different from those before and after, the key frames are automatically created. This is the so-called difference animation principle.

6. five basic properties of A layer: Axis (A), position (P), size (S), rotation (R), opacity (T ), press f to hide all attributes, and press the shortcut keys of each attribute to bring up an attribute separately. (If you want to display multiple attributes, you can press shift and then press the shortcut key for other attributes)

7. The keyboard's 0 Key is the rendering shortcut key

8. The left parenthesis key [can keep the left boundary of the clip close to the timeline pointer. Likewise, the right parenthesis key] can keep the right boundary of the clip close to the timeline pointer.

9. The key frame finder is shown in the red circle. The diamond square in the middle indicates that the current time point has a key frame. You can click the left and right arrows to move the timeline pointer to each key frame.

10. To establish a link between a layer and another layer, use the parent-child relationship. After the parent-child relationship is established, the parent layer changes, the child layer will also change (but the transparency will not be affected), just as the child layer is embedded in the parent layer. However, changing the child layer does not affect the parent layer.

11. Dynamic blurring. This must be added to blur the motion of a moving object. The top is the master switch, and the bottom is the switch of each layer. (Fuzzy parameters can be set in the advanced options of the new merging window)

12. PressBKey to set the start end of the work area (based on the position of the current timeline pointer), PressNKey to set the end of the work area (based on the position of the current timeline pointer)

The cropping work area can be used to cut out content outside the work area (image synthesis-trim and merge to work area)

13. Use Image Synthesis-to make a video to output the video (you can output the image sequence string ). You can also export swf files in file-export.

14. When importing a psd file, you can select the compositing-cropping layer to create a new compositing for the imported psd file and retain the original layers of the psd.

15. When performing operations on a layer, you can select multiple layers. Then, you only need to operate any of the layers, and the other layers will also change.

16. click the button in to expand the layer's entry point, exit point, and duration panel to precisely control the entry and exit points and duration of the layer.

The scaling (which can also be translated into a rate) is used to control the playback rate of the clip (for example)
