About this Viewer
The ASS Viewer lets you inspect Advanced SubStation Alpha subtitles, including karaoke timing and styled dialogue, directly in the browser.
Review dialogue blocks exported from Aegisub or other subtitle editors before sharing them with collaborators or encoding workflows.
Quickly validate that styles, timing, and text content align with your creative intent without opening desktop software.
Best Practices
- Confirm the [Script Info], [V4+ Styles], and [Events] sections are present.
- Use consistent style names and reference them in dialogue events.
- Check start and end times for overlaps when using complex effects.
- Escape line breaks with \N inside dialogue text to control layout.
- Keep margins and alignment consistent for your target video resolution.
