GlueMotion is a lightweight and efficient stop-motion animation and GIF creation software designed specifically for macOS. It is renowned for its intuitive interface and powerful Onion Skinning feature, making it ideal for animation beginners, educators, and content creators who want to quickly produce smooth frame-by-frame animations.

1. Detailed Explanation of the Core Interface and Workspace

After launching GlueMotion, you will see a clean main interface with clearly divided functional areas. It is mainly divided into the following sections:

Top Menu Bar and Toolbar: Contains buttons and menus for all main commands such as file operations, editing, view, and animation control. The toolbar is customizable, and commonly used functions such as play, add frame, delete frame, and onion skin toggle are all located here.
Central Canvas/Viewing Area: This is the preview and drawing area for the animation. You can zoom and pan to view details. The background color and grid lines can be adjusted in the “View” menu.
Bottom Frame Management Timeline: This is the core workspace of GlueMotion. Each cell arranged horizontally represents one frame. Here you can select, copy, and reorder frames. Above the timeline are playback control buttons (play, loop) and frame rate (FPS) settings.
Right Properties Panel: Dynamically displays relevant properties based on the selected object (frame, layer), such as adjusting frame delay time, applying filter effects, or managing layer opacity.
Left Toolbar: Provides drawing tools (such as brush, eraser, fill bucket), color picker, and layer management list. In GlueMotion, each frame can contain multiple layers, making it easy to separate the background and animated elements.

II. Complete Workflow: From Creation to Export

Step 1: Create or Open a Project

Method: After launching the software, click the menu bar File → New... or use the shortcut Cmd + N. In the pop-up dialog, set the canvas size (e.g., 1080×720), background color, and initial frame rate (usually 12 or 24 FPS). To open an existing project, use Cmd + O.

Step 2: Import Assets or Start Drawing

Method: You can draw the first frame directly on the canvas using the drawing tools on the left. If you need to import an image sequence or video as a base, click the menu bar File → Import Media.... After selecting the files, GlueMotion will automatically decompose them into consecutive frames and insert them into the timeline.

Step 3: Add and Manage Frames

Core Operations:

Add New Frame: Click the “+” button on the right side of the timeline, or press the shortcut Cmd + B. The new frame will automatically inherit the onion skin reference from the previous frame.
Duplicate Frame: Select one or more frames on the timeline (hold Shift for multi-select), press Cmd + C and then Cmd + V to paste.
Delete frames: After selecting a frame, press the Delete key.
Reorder: Simply drag and drop frames directly on the timeline.

When drawing, be sure to enable the “Onion Skin” button on the toolbar (or use Cmd + Shift + O). This feature displays the content of the previous and next few frames in a semi-transparent manner, which is key to ensuring motion continuity.

Step 4: Animation Preview and Adjustment

Method: Use the play button above the timeline (the spacebar can also control play/pause) to loop the animation preview. If you need to adjust the display duration of a particular frame, select that frame on the timeline, then modify the “Delay Time” (in hundredths of a second) in the properties panel on the right. To adjust the overall animation speed, modify the frame rate (FPS) value in the upper-left corner of the timeline.

Step 5: Export the Final Animation

Method: Click the menu bar File → Export... or use the shortcut Cmd + E. In the export dialog:

Select Format: GlueMotion supports exporting to GIF, MOV, MP4, PNG sequence, JPEG sequence, etc.
Set Parameters: For GIF, you can set the number of colors and the dithering algorithm to optimize file size and image quality; for video, you can choose the encoder and quality.
Specify path and export: Choose the save location and click the “Export” button.

III. Advanced Tips for Common Features

Efficient drawing tips:
- Use the number keys 1-0 to quickly switch brush opacity (10% to 100%).
- Hold the Spacebar to temporarily switch to the hand tool and pan the canvas.
- Use Cmd + Z to undo and Cmd + Shift + Z to redo; history can be viewed in the “Edit” menu.
Advanced onion skin settings: Click the dropdown arrow next to the “Onion Skin” button to customize the number, color, and opacity of previous and next reference frames, making it easier to distinguish actions at different stages.
Layer management: Add multiple layers to each frame (such as “static background layer” and “dynamic character layer”). In the layer list on the left, click the eye icon to hide/show a layer, and click the lock icon to prevent accidental edits. Placing the character on a separate layer can avoid redrawing the background every frame.
Reverse frame sequence: Select some frames on the timeline, right-click and choose “Reverse” to quickly create a back-and-forth motion animation, saving effort.

IV. Common Problems and Solutions

Q1: The animation feels laggy or not smooth during playback?
A1: First, check whether the frame rate (FPS) in the settings is too high. An excessively high FPS requires more frames to be drawn to play smoothly. It is recommended to start at 12FPS. Second, check whether the canvas size is too large; an oversized canvas consumes more system resources, so reduce it appropriately.

Q2: Exported GIF file size too large?
A2: When exporting a GIF, try the following: 1) Reduce the number of colors (e.g., down to 128 or 64 colors). 2) Enable the dithering option, which helps maintain better visual quality when colors are reduced. 3) Use a smaller canvas size when creating the project.

Q3: Accidentally deleted or overwritten an important frame?
A3: Immediately use Cmd + Z to undo. GlueMotion supports multi-step undo. If the project has not been closed yet, you can try restoring to a previously saved version via the “Revert To” feature in the “Edit” menu. Make it a habit to press Cmd + S frequently to save — it’s crucial.

Q4: How to turn live-action photos into stop-motion animation?
A4: Use the “Import Media” feature to import a sequence of photos. Make sure the photos are named in order. After importing, use the timeline to check each frame. You can use the built-in “Image Adjustments” tool (in the right-side properties panel) to batch or individually adjust brightness and contrast, making the color tone of the footage consistent.
