FAQ

What file types and input sources can I use with the free subtitle generator?

Upload common local media (MP4, MOV, MKV, MP3, WAV, M4A) or paste public video URLs such as YouTube and Vimeo. Meeting exports from Zoom/Teams and podcast episode files are also supported.

How do I export captions for YouTube, Vimeo, or social platforms (SRT vs VTT)?

Choose SRT for broad compatibility with YouTube and many editors. Use WebVTT when you need styling markers or platform-specific features. The tool provides presets that format cue length and breaks for social or long-form uploads.

Can I edit timestamps and speaker names before downloading subtitles?

Yes. The inline transcript editor lets you correct text, rename detected speakers, split or merge cues, and adjust timestamps prior to export.

How accurate are automated captions with noisy or multi‑speaker audio, and how can I improve transcripts?

Accuracy depends on audio quality and overlap. To improve results, provide clearer audio (use a direct feed or higher bitrate), remove background noise where possible, and use the editor to correct speaker labels and punctuation after automatic transcription.

Does the tool translate captions to other languages and preserve timing?

Yes. You can translate captions while preserving timestamps. Machine-translated lines are marked for review so editors can verify accuracy before exporting.

Is there a batch mode for generating subtitles for multiple files at once?

The free in-browser tool focuses on single-file workflows. For batch processing and folder exports, check our product pages to see available paid or enterprise options (see /pricing).

What controls are there for social media caption formatting (line length, font-readability)?

Use the social presets to limit characters per line and break cues into short, readable segments. You can further fine-tune cue timing and spacing in the editor to ensure readability on mobile devices.

How does the free tool differ from Texta’s paid subtitle and monitoring features?

The free generator provides in‑browser transcription, editing, and export for individual files. Paid offerings expand to batch processing, integrations, persistent project storage, monitoring, and team workflows — see /pricing for details.

What privacy and storage policies apply to files uploaded to the subtitle tool?

The tool uses a processing workflow that surfaces captions for review and export. Users should consult the site privacy disclosure for details on retention, deletion controls, and any account-based storage options.

How do I use the generated SRT/VTT with a video editor or CMS?

Download the SRT or VTT file and import it into your editor (Premiere, Final Cut, DaVinci) or upload to your CMS or platform (YouTube accepts SRT). For VTT styling, import according to your platform’s VTT support and verify cue timing in playback.
