Selecting the correct duration setting: Custom, Single Frame, Constant, or Write On
When it comes to setting the paint frame duration in After Effects, selecting the appropriate duration setting is crucial. The available options include Custom, Single Frame, Constant, and Write On, each serving a distinct purpose.
Let's delve into each of these options:
Custom: The Custom setting offers unparalleled flexibility in defining the duration of your paint frames. You can specify the exact number of frames you want your paint strokes to remain on-screen. This option is ideal when you require precise control over the timing of your animations. To set a custom duration, head to the Paint panel, choose "Custom" from the Duration menu, and input your desired frame count.
Single Frame: The Single Frame option is perfect when you want your paint strokes to appear only on a specific frame. This setting ensures that each stroke is confined to a single frame, making it useful for detailed frame-by-frame animations. To achieve this, set the Duration value to 1 in the Paint panel.
Constant: While not explicitly mentioned in the sources, the Constant setting likely refers to maintaining a consistent duration for all paint strokes throughout your animation. This setting would be valuable when you want a uniform timing for your paint effects across multiple frames.
Write On: The Write On setting introduces an element of automation to your paint strokes. By selecting this option from the Duration menu in the Paint panel, you can automatically animate the End property from 0% to 100%. This creates the illusion of a paint stroke being drawn over time. It's an excellent choice when you want to simulate a drawing process or create a revealing effect for your paint strokes.
Remember, the choice of duration setting depends on the creative requirements of your project. Experiment with these settings to find the one that best suits your desired outcome in After Effects.

Using the Write On setting to make a paint stroke appear to be drawn over time
To make a paint stroke appear to be drawn over time using the Write On setting in After Effects, follow these steps:
Firstly, select your desired paint tool from the Tools panel. This could be the Brush, Clone Stamp, or Eraser tool. You can also create a new preset brush by specifying your desired settings in the Brushes panel and then choosing "New Brush" from the same menu.
Next, in the Paint panel, choose "Write On" from the Duration menu. This setting applies the stroke from the current frame to the end of the layer's duration and automatically animates the End property of the stroke to match the motion with which it was drawn.
Now, in the Layer panel, drag with the Brush tool to start painting on the layer. Your movements will be recorded in real time, determining the rate at which the stroke is drawn on the screen. Recording begins when you click within the layer in the Layer panel, and it ends when you release the mouse button.
To create a new stroke, simply drag again with the Brush tool. If you want to resume drawing the previous stroke, use the Shift key while dragging. You can also modify the Start and End properties of a paint stroke to control how much of it is shown at any given time. For example, by animating the End property from 0% to 100% with the Write On setting, you can make the stroke appear as if it's being drawn over time.
Additionally, you can link the paint stroke properties to other properties using expressions. For instance, you can make a paint stroke follow a moving element in your footage by tracking that element and then linking the Position property of the stroke to the Attach Point property of the tracker.
By following these steps and experimenting with the various tools and settings, you can create dynamic and visually appealing paint animations in After Effects.

Using the Clone Stamp Tool to sample pixels and paint over objects
The Clone Stamp tool in After Effects is a valuable resource for video editors and animators who want to improve their projects. It can be used to remove unwanted elements, duplicate objects, and create impressive visual effects.
The Clone Stamp tool samples pixels from a source layer and applies those pixel values to a target layer. The target layer can be the same as the source layer or a different layer within the same composition. When the source and target layers are the same, the Clone Stamp tool samples paint strokes, effects, and the layer source image. When they are different, you can open each layer in a separate viewer and lock the current viewer.
To clone an area, you need to set a source point. Hold down the Alt key (Windows) or Option key (Mac) and click on the area of the layer you want to clone. This establishes the point from which the Clone Stamp tool will duplicate pixels. Choose an area that closely matches the region you want to cover or duplicate.
After setting your source point, start painting over the area to apply the clone. Click and drag over the area to modify, and the cloned pixels will appear in real-time. Work gradually and carefully to ensure seamless blending. If you make a mistake, press Ctrl + Z (Windows) or Cmd + Z (Mac) to undo your last action.
Once you’ve completed the initial cloning, review your work and make any necessary adjustments. You can refine the cloned area by modifying the brush’s opacity or size.

Painting on individual frames to create an animation or obscure unwanted details
Painting on individual frames is a great way to create animations or remove unwanted details from your footage. This technique is called rotoscoping and can be done in Adobe After Effects using the Paint panel and Brushes panel.
To get started, open your footage in the Layer Panel and select the Brush Tool. In the Paint panel, you can choose from three duration settings: Single Frame, Constant, or Custom. Single Frame applies the stroke to just one frame, Constant applies it from the current frame to the end of the layer's duration, and Custom lets you specify the number of frames your stroke will occupy. If you want to paint on each frame, set the duration value to 1.
Now, you can start painting on your layer. Each time you release the mouse button, you'll create a new stroke. If you want to continue working on the previous stroke, use the Shift key while dragging. You can move forward or backward through the frames using the main keyboard: press 1 to go back and 2 to advance by the number of frames specified in the Duration setting.
To create an animation, simply draw on each frame, advancing to the next one when you're done. You can also use the Clone Stamp Tool to sample pixels from one area and paint them onto another, which is great for removing blemishes or unwanted objects.
For more advanced techniques, you can explore keyframing, where you animate each stroke by keyframing the End parameter from 0% to 100%, revealing the stroke over time. You can also try rotoscoping, which involves tracing over individual frames, and even create animated masks to isolate or remove elements from your video.

Manually adjusting brush positions frame by frame
To begin, open After Effects and create a new project. Import your video file by going to File > Import > File. Drag the clip into a new composition and ensure your footage is trimmed and ready before starting.
Next, open the source layer in a Layer panel. You can do this by opening a composition containing both the source layer and the target layer. Move the current-time indicator to the frame where you want to start sampling. You can manually adjust the time and coordinates of the sampling start point by modifying the Offset, Source Time Shift, Source Position, or Source Time values in the Paint panel.
Select your paint tool from the Tools panel and choose your desired settings and brush in the Paint panel and Brushes panel. In the Layer panel, drag with the Brush tool to start painting on the layer. Each time you release the mouse button, you stop drawing a stroke. To create a new stroke, drag again. To continue drawing the previous stroke, Shift-drag.
To adjust the brush size, you can create a mask and add the Saber effect from Video Copilot to change the ending sizes and animate the stroke. Alternatively, you can fake it by selecting different brush sizes every few frames.
To work on individual frames, set the Duration value to 1 in the Paint panel. This ensures that your paint strokes will only be visible for one frame. You can move forward or backward in the timeline by pressing Command + Left Arrow or 1 or 2 on your keyboard to move the current-time indicator forward or backward by the number of frames specified in the Duration setting.
Repeat the drawing process for each frame until your animation is complete. You can preview your work by dragging the playhead to the beginning and pressing the spacebar to play your animation from the start.
