Choose for the destination
Ask your video editor, player or publishing platform which format it accepts. SRT is a common interchange choice for numbered subtitle cues. WebVTT is designed for timed text on the web and works with HTML video tracks. Neither format changes the underlying video. Downloading a subtitle file does not burn words into the picture or publish your content anywhere.
What changes between the files
An SRT cue includes a number, a start and end time, then its text. Milliseconds follow a comma. WebVTT starts with a WEBVTT header and uses a dot before milliseconds. This app exports plain timed text in both formats; it does not create advanced WebVTT regions or styling. Both exports come from the same canonical segments, so choosing a different format does not run transcription again.
Understand which text you are exporting
The readable document can be edited and checked separately from the timestamped result. Copy Text and TXT follow the selected document version. SRT and VTT retain the original recognition output and times. If you accepted spelling corrections in the document, do not assume they appear in the subtitle file. Open the exported captions in your subtitle editor and make the corresponding changes there.
Review timing, readability and direction
Play the video with the subtitle track enabled. Check that cues appear with the right speech, do not stay too long, and leave enough time to read. Model timestamps are estimates. Segments without valid times are excluded rather than assigned fictional timing. For Arabic, inspect punctuation, numbers and text direction in the actual destination player. A correct file can still be displayed differently by different players.
Keep an editable source
Save the original recording, subtitle file and any revised copy until publication is complete. JSON is useful when another workflow needs the original segment data. This tool does not add speaker identities, non-speech sound descriptions or a full accessibility caption pass automatically. Those details require human review appropriate to the recording and its audience.
