Design overlays for the real output canvas, verify text and alerts over representative footage and package the working assets with a tested fallback.
Identify the content area, camera, captions, alerts and any required sponsor information. Choose the actual output orientation and dimensions, then check their aspect ratio. Prioritize what viewers need during each scene and identify regions used by the game or presentation. Avoid assigning a universal safe-zone percentage.
Use stills or recordings from the intended content to set text panels, camera framing and alert positions. Compare a busy frame and a sparse frame. Preview at the actual player size, including a phone, and leave room for captions and interface controls. Record the chosen dimensions and transforms for each asset.
Use readable wording and test the longest expected names or messages. Compare foreground and opaque backing colors in the contrast checker. WCAG AA uses 4.5:1 for normal text and 3:1 for qualifying large text; verify the actual rendered size and background. Color alone should not carry the meaning of an alert.
Use motion only where it communicates useful status. If an animation uses an unpadded sprite sheet, enter its full dimensions and row/column counts to calculate exact cell dimensions; the rendering code still needs to select and time the frames. For browser widgets, configure the intended viewport and test refresh and hidden-state behavior in OBS.
Trigger long text, rapid consecutive alerts, missing avatars, a disconnected widget and a scene change during an animation. Watch for clipped text, overlapping captions and leftover audio. Record a representative sequence and inspect OBS rendering/encoding statistics before and after adding the overlay. Simplify the element that causes a measured problem.
Export static and animated assets with their intended names, dimensions and required fonts or licenses. Save the browser files, configuration and a static fallback for unavailable widgets. Reopen the scene collection on the intended machine and confirm asset paths. Download the layout and test record with the version that passed.
Check the output and asset proportions before positioning.
Compare the chosen text color with a stable opaque backing.
Calculate exact cell dimensions for an unpadded divisible sprite sheet.
Draft and download the overlay asset sheet and test findings.
Loading your checklist…
WCAG defines minimum text contrast and the conditions for large text. The contrast calculation alone does not assess the complete viewing experience.
Browser-source dimensions control its viewport; refresh and shutdown settings affect widget state.
Keep these task-specific records with the tested version and review date.
| Record | Include | Verify |
|---|---|---|
| Static panel | File, dimensions, color pair and transform | Readable at output player size |
| Animation | Frames, timing, viewport and trigger | No collision or lingering audio |
| Fallback | Local file and activation action | Works without the remote widget |
Use long display names and realistic multi-line alerts during layout work.
A simple local overlay can keep the program understandable while a remote widget recovers.
