Instructions

Software Usage Instructions

Enter subtitle text: Select “Single generation” to enter one subtitle, or select “Batch generation” to enter one subtitle per line. Batch mode only displays the first 20 items for review, but all text will be processed when generating.
Set the LED effect: Adjust parameters such as canvas width and height, LED dot size, dot spacing, LED dot shape, glow intensity, background LEDs, background color, and transparent background.
Set the color mode:
- Solid color: Suitable for common sign effects such as red, green, yellow, and white.
- Gradient: Set the start color, middle color, end color, and gradient direction.
- Rainbow: Create multi-color flowing dot-matrix subtitles.
Adjust font layout: Select the font, font weight, font size, letter spacing, horizontal alignment, vertical position, line height, and margins. After enabling automatic font size fitting, static subtitles will be displayed as fully as possible.
Select animation parameters: Supports static, scroll left, scroll right, scroll up, scroll down, blinking, and breathing brightness effects. You can set speed, duration, frame rate, loop count, motion trail, border, and scan lines.
Select export format:
- GIF: Suitable for creating animated scrolling subtitle images.
- PNG: Suitable for static subtitle images.
- WebP: Suitable for web image assets.
- Frame-by-frame PNG ZIP: Suitable for video editing and post-production compositing.
Save and load settings: Frequently used sizes, colors, animation, and layout parameters can be saved and quickly loaded later for continued use.
Generate and download: After confirming the preview effect, single generation will download the file directly, while batch generation will package the files into a ZIP file.

FAQ

A: You can create effects such as dot-matrix LED signs, storefront signs, marquee text, announcement bars, event promotional subtitles, and video intro subtitles. Exporting as static images and scrolling animations is supported.

A: We recommend using a dark background, selecting a circular LED dot shape, setting the dot size to 3-6px, setting the dot spacing to 1px, and appropriately enabling background LEDs, glow, scan lines, and border brightness.

A: You can reduce the canvas size, shorten the animation duration, lower the frame rate, reduce the quality, increase the LED dot size, or switch to formats such as PNG, WebP, or frame-by-frame PNG ZIP.

A: You can enable automatic font size fitting, increase the canvas width or height, reduce letter spacing and margins, or switch to common Chinese fonts such as Microsoft YaHei, SimHei, or SimSun.

A: Batch generation uses each line of text as the file name and automatically replaces characters that are unsuitable for file names. If duplicate names occur, a numeric suffix is automatically added to distinguish them.

A: Transparent backgrounds are suitable for PNG and WebP, for overlaying on posters, video footage, live stream assets, or webpage backgrounds. GIF transparency is limited by encoding, so complex glow effects may not look natural enough.

A: Animated images require frame-by-frame drawing and encoding. The larger the canvas, the longer the duration, and the higher the frame rate, the more time it takes. You can preview with a smaller size first, then increase the output parameters as needed.
