Start with the sound you want to understand

The first useful check happens before transcription: listen to the correct audio track. A file can contain original dialogue, dubbed voices or commentary. Source-language detection and the target subtitle language are separate settings. Choose the speech you want first, then the text you want to read.

Choose the right audio track

Choose a file that fits your player

SRT is a practical starting point for ordinary local playback. VTT is useful when a website expects a WebVTT track. ASS provides richer styling in compatible players, including a clearer distinction between original and translated lines. The best choice depends on where the subtitle will be used, so inspect the actual destination application.

Compare SRT, VTT and ASS

Add a subtitle to a local video

Keep videos and subtitles associated

Use clear filenames and organize each subtitle beside the exact video version it accompanies. Several language files can share a base name while using different language suffixes. A rename helps discovery; it does not repair timing differences between two edits of a movie.

Name subtitle files consistently

Package a checked result for delivery

External, embedded and burned-in subtitles solve different delivery problems. Keep an editable subtitle and the original video before creating a packaged or rendered copy. Review names, timing and readability before making the text a permanent part of the picture.

Diagnose a problem without starting over

An interrupted upload, an incorrect audio choice and a player displaying the wrong track need different fixes. Check the task state before creating a replacement, then follow the relevant symptom. If you need support, the task identifier and visible error are more useful than sending an entire video.
