Uploaded SRT / WebVTT is selected.
Subtitle operation
Keep / add a subtitle track.
Output container

What to check before exporting
This operation uses supplied subtitles and does not generate text from speech. Subtitle format and styling depend on the destination container; explicit processing simplifies styling to plain text.
Choose a compatible output profile and review the source streams, selected range and final settings. Processing uses structured controls, and incompatible combinations are rejected before queueing. Download the requested result when final validation completes.
A real workspace. A result you can inspect.
This actual product screenshot shows source playback, range selection, an uploaded-audio area and encoding settings. It illustrates the shared converter; your operation opens its own relevant controls after inspection.
A processed preview creates a separate short task. It covers the first ten seconds of your range at up to 360p in a compatible format. Image and subtitle exports still need inspection of the requested final download.

Questions about this workflow
Will the subtitles always appear in a browser player?
Browser support varies. A selectable track needs player support; burn text into the picture when the captions must be visible as pixels.
Can I close the tab while processing?
Yes. Submitted conversion tasks run in the background. Return to your account to check progress and download results before the retention period ends.
What are the upload and storage limits?
Current source limits are 2 GiB and two hours per file. Files have a 72-hour retention period; task, collection and resource limits also apply. The workspace shows the applicable limits. Free and Pro currently share feature access.
