课程名称：使用After Effects Expressions的高级运动图形 课程概述： 《使用After Effects Expressions的高级运动图形》是一个专为创意专业人士设计的课程，After Effects软件广泛用于制作运动图形和视觉特效。该软件作为行业标准，被专业人士和爱好者广泛使用。本课程重点介绍After Effects Expressions的应用，帮助学员掌握自动化工作流程并节省时间，从而区分初学者与专业人士的差异。 在本课程中，学员将学习到多种After Effects表达式的基础知识和实际应用。具体内容包括： 1. **Wiggle表达式**：通过调整频率和幅度为物体的位置、旋转、不透明度、比例等添加运动。 2. **时间表达式**：实现物体的加速、减速以及使物体在时间延迟的情况下跟随另一个物体。 3. **Value at Time方法**：获取任何物体的变换属性的坐标或值，并将其传递给另一个物体的变换属性。 4. **数学四舍五入**：对任何属性值进行四舍五入并在屏幕上显示。 5. **Loop In**：通过重复一组关键帧来自动化工作流程，节省设置重复关键帧的时间。 6. **Loop Out**：类似于Loop In，在图层的时间线结束之前重复一组关键帧。 7. **随机方法**：生成指定范围内的随机值，并用于触发各种效果。 8. **Length方法**：计算变化值的长度，如两点之间的距离。 9. **If Else条件逻辑**：实施条件逻辑以创建高级运动图形。 10. **时间延迟**：相对于其他物体的时间触发效果，实现有无延迟的效果。 本课程将通过实践课程让学员掌握这些表达式的写作方法和技巧，适合希望提升After Effects技能的专业人士。
After Effects is widely used to create motion graphics and visual effects. Creative professionals also use this powerful software to create cool animations. It is the Industry standard widely used by both professionals and enthusiasts. But what factors distinguish After Effects Professionals from beginners? What is After Effects Expressions?Expressions. Professionals write After Effects expressions to automate their tasks, speed up their work, saving time from things that beginners do a lot- Creating repetitive keyframes. Expressions also let you add various advanced functionalities allowing you more control over properties and attributes such as over time, frequency, amplitude, conditionals and loops, etc.This course will teach you After Effects expressions right from the fundamentals, where you will learn various methods and ways to write expressions with practical lessons.In this course you will be learning following variety of After Effects expressions:Wiggle Expression- Add motion to any object in terms of position, rotation, opacity, scale by manipulating its Frequency and Amplitude.Time Expression- Speed up and slow down anything, make any object follow another object with time delay, etcValue at Time method- Fetch coordinates or value of any transformation property of any object and pass it to another object's transformation property based on time.Math round- You can round off value of any property to its decimal value and can display it on the screen.Loop In- Automate your workflow by repeating a set of keyframes (two, three, and more) right from the beginning of the timeline of a layer to the set keyframes. This method can save a lot of time used for setting repetitive keyframes.Loop Out- Similar to Loop In, looping set of keyframes till the end of the timeline of a layer. It doesn't start at the beginning of the time, rather from the time you set the looping keyframes.Random method- You can generate random values within a range provided as parameters in the Random method. The generated values can be used to trigger various effects and change values of various transformation properties.Length- This method can be used to calculate length of any change in values such as distance between two points, etc.If Else- You can implement conditional logic to create advanced motion graphics. You can specify various conditions and actions to perform based on situations. It is one of the core building block of any programming language.Time delay- You can trigger any effect on a object relative to other object's time with and without any delay.
