Start with a clean clip
Choose a clip with clear speech and trim the pauses you already know you do not need. Better source audio gives speech recognition fewer ambiguities to resolve.
Generate the first caption pass
Use automatic transcription as a starting point, then read every line while the video plays. Names, product terms and accents deserve a quick human check.
Make captions easy to read
Keep each caption short, place it where it does not cover the subject, and use one visual style consistently. Highlighting a key word can guide attention, but every line should remain legible without the effect.
Export and review
Watch the final export once with sound off and once with sound on. Check timing at sentence changes, confirm punctuation, and make sure the export resolution suits the platform where it will be posted.
