Format Details
SSA
SSA (SubStation Alpha) is the predecessor to the more capable ASS format, offering more styling options than SRT while being simpler in structure than ASS. It supports custom fonts, colors, positioning, and basic animation effects, and was the standard subtitle format in anime fansubbing communities before ASS gained prominence. SSA and ASS files share a similar file structure and are often treated interchangeably by modern media players.
SUB
SUB (MicroDVD Subtitle) is a subtitle format that stores timing as video frame numbers rather than absolute timestamps, making it intrinsically frame-rate dependent. Each subtitle entry uses curly-brace notation for frame numbers and supports basic inline formatting. SUB is a legacy format from the DVD ripping era that is still supported by major media players, though SRT and VTT have largely replaced it for new subtitle content.
