FAQ

What does quality check?

TimedSubs checks for subtitle issues that commonly block delivery: overlapping lines where two subtitles share the same time window, durations that are too short or too long for the text to be readable, incorrect subtitle-line ordering, line lengths that exceed viewer readability limits, and characters-per-second rates that make subtitles pass too quickly. Export is gated until blocking issues are resolved.

Is quality plan-gated?

Basic quality checks — overlap detection, duration checks, and export gate status — are available on all plans including Free. More detailed quality reporting, batch delivery evidence, and ZIP delivery packaging are features of Studio and Agency plans. If an issue blocks export, it stays visible regardless of plan until it is resolved or the project is re-processed.
