PRACTICAL REFERENCE
Understand the file you are fixing.
Worked examples with transparent calculations and specific limits. Use them alongside the video and your delivery specification.
Find an SRT timestamp error without losing a cue
Read a SubRip block, separate formatting from timing problems, and make the smallest safe correction.
Move every SRT subtitle earlier or later
Choose the correct offset, understand negative-time protection, and recognize drift that a fixed shift cannot solve.
Understand a subtitle reading-speed warning
Calculate characters per second and use it as an editorial signal without mistaking it for an accessibility certificate.
Decide whether a subtitle overlap needs fixing
Measure adjacent overlaps and distinguish a timing problem from an intentional presentation choice.
