Does this play the subtitles against a video?

No — we render the subtitle file as a styled table, not synced playback. For burn-in or live playback you want libass via subtitles-octopus paired with a video element, or VLC / MPV with the .ass loaded as an external track.

Why don't I see karaoke timings or {\fad(…)} effects?

Override tags are stripped from the preview text so the table stays readable. The raw event text is still in your file untouched — the table just hides the tags so dialogue reads cleanly.

Why are the colors swapped (BGR vs RGB)?

ASS encodes PrimaryColour as &HBBGGRR& — blue in the high byte, red in the low byte. We swap the channels when converting to CSS so the swatches and preview text show the correct color.

No. The ASS file is read entirely in your browser. Nothing is sent to a server.

About ASS / SSA

Advanced SubStation Alpha styled subtitles.

ASS (Advanced SubStation Alpha) is the format anime fansubs adopted because it ships styled text, positioning, and karaoke effects in a single human-readable file. We parse the Script Info, V4+ Styles, and Events sections natively. Each event is rendered with its style's font and primary color so you can preview the look of every cue. Override tags ({\…}) are stripped from the preview text — the raw form remains in the source. A free-text filter searches dialogue, style, and actor at once.
