Begin after the episode edit is finished
A podcast episode may have a new introduction, removed pauses and advertising inserted after the interview is recorded. Generate subtitles from the actual video you will publish. Using the raw conversation as a timing reference can leave captions out of step as soon as the first edited section begins. Keep the episode number and edit version in your filenames.
Import the finished video into Polyglot and create a source-language draft on your Mac. Transcription and translation stay local after model setup. Begin review with a difficult passage, such as quick discussion or a remote guest with uneven audio, before working through the full episode. Recognition quality should be assessed on the real conversation.
Make recurring names and terms consistent
Keep guest names, organizations, book titles and specialist terms in a reference note. Check these manually as you review; Polyglot does not automatically train on your episode glossary. A familiar-sounding alternative may be perfectly spelled and still be the wrong person or product. Listen again when the text and context disagree.
Pay attention to interruptions and corrections. If a guest says a number and then corrects it, the final captions should convey what viewers hear without making the first number look like the settled answer. Polyglot does not automatically label speakers. Add any speaker context needed for the finished captions through your review and finishing workflow.
Treat clips as separate subtitle deliveries
A thirty-second excerpt has a different start time from the full episode. Cropping, jump cuts and a new hook can change its structure further. Create subtitles from the final clip or finish its timing in a suitable editor. Polyglot does not automatically convert a full-episode SRT into synchronized tracks for every promotional edit.
Choose the delivery style intentionally. An SRT track can be attached to a compatible player and selected by the viewer. Permanently visible, animated social captions require a separate video-editing step; the app does not burn them into the image. Check the rendered clip on the intended screen size so the caption treatment does not obscure faces or other necessary information.
Publish and preserve the reviewed episode
Export UTF-8 SRT with the episode identifier, edit version and language. YouTube documents an upload option for subtitle files with timing, linked below. Confirm the supported format and language settings for your host, attach the file, then preview the actual published player. The app does not automatically upload to a podcast or video service.
Inspect a late section after any ad break as well as the opening. For translations, have a fluent reviewer check guest idioms and references; translation targets do not expand the 25 European speech-recognition languages. Save the project and approved exports together. If you replace an ad or introduction later, recheck the subtitle track against that new episode version before publishing it.
