Good to know
An .srt file sits next to your video and only shows up if the player loads it: YouTube, Vimeo and VLC do, but on WhatsApp, Instagram or inside a PowerPoint it goes missing. Burned-in subtitles are part of the picture, so they travel with the video wherever it ends up, even when someone forwards it. The trade-off is that nobody can switch them off and you can't translate them later. Keep the original video and the .srt file, and burn the text only into the copy you publish.
Every line is one cue: start, end, then the text, with the timing in seconds or as mm:ss. To break a cue over two lines, put a | between the two parts. Keep a cue between one and five seconds and stay under about forty characters per line; beyond that nobody keeps up while you carry on talking. Already have an .srt or .vtt from a transcription service? Import it and fix only the sentences that read awkwardly. The preview shows straight away whether the text appears at the right moment.
Burning in subtitles happens in your own browser, and the file stays on your computer — handy for a recording of a meeting or a client call. An MP4 or MOV is processed frame by frame and is usually done well within the running time; a WebM is recorded in real time, so keep the tab open. You get a new file back, MP4 by default; your original stays unchanged. Long sentences wrap onto two lines automatically. Choose white with a black outline or a dark bar, at the bottom or the top — on TikTok or Instagram, check that the app's buttons do not cover them. With 'Save as .srt' you keep the subtitles as a separate file too. If the result is too large for email, send it as a download link.
