Auto Subtitle & Caption Generator — Frame-accurate subtitles in more than 40 languages, styled to your brand, burned in or exported as a subtitle file.
What Auto Subtitle & Caption Generator does
Auto Subtitle & Captions transcribes your audio and turns it into captions that are actually pleasant to read. Lines are broken at natural speech boundaries rather than at arbitrary character counts, timing survives fast dialogue, and speaker changes are detected. You get full control over styling — font, weight, colour, position and animation — and you can export SRT, VTT or burn the captions permanently into the picture.

Why teams choose Auto Subtitle & Caption Generator
Most AI video tools optimise for a single impressive demo. Auto Subtitle & Caption Generator is built for repeatable output — the same settings produce the same quality on the hundredth export as on the first, and everything you create stays editable. That matters when a campaign needs twenty variants, when a client asks for one more revision, or when a series has to look consistent across a whole season of work.
It also fits into the rest of the OpenFilmo pipeline. Assets you create here can be finished with our other tools, and your brand kit carries through automatically so nothing leaves the studio off-brand. Commercial use is included on every paid plan, exports are watermark-free, and nothing you make is locked to a format you cannot change later. Start with a single render, or compare the plans on our pricing page.
Frequently asked questions about Auto Subtitle & Caption Generator
How accurate is the transcription?
On clear audio it is typically above 95 percent word accuracy, and you can correct anything it misses before export.
Can I translate the captions into another language?
Yes. Transcription and translation are separate steps, so you can produce several language versions from one clip.
Can I style the captions to match my brand?
Yes. Fonts, colours, outlines and animation are all configurable, and you can save a style as a preset.
Does it handle multiple speakers?
Yes. Speaker detection labels who is speaking and can apply a different caption colour to each voice.
