Direct answer
Reviral's AI subtitle generator transcribes speech from an uploaded video, aligns words to the audio, and burns the chosen subtitle style into a new video export. You can select from 22 animated treatments while keeping the original sound. The route does not promise a fixed accuracy rate, automatic speaker labels, translation, or downloadable SRT and VTT files.
Ways to use this tool
Subtitles for product demonstrations
Make spoken instructions visible in an exported demo, then verify terminology and measurements against the source.
Educational clip subtitles
Caption a concise lesson or explainer where correct names and specialist words can be checked before publishing.
Interview excerpt subtitles
Process an already-edited interview clip while keeping the original audio; participants are not labelled automatically.
Silent-feed viewing support
Keep the spoken message visible for viewers who encounter the video with device sound muted.
How it works
Step 1
Provide the video upload
Select the completed clip that contains the speech you want transcribed into visible subtitles.
Step 2
Choose style and position
Pick one of 22 animated looks and place the text where it best fits the frame.
Step 3
Create the subtitled export
The system times words against the audio and renders them permanently into the video picture.
Limits to know before you start
- This workflow does not translate speech or expose a stated subtitle-language count.
- There is no guaranteed accuracy figure, so the finished wording needs a human review.
- Separate SRT, VTT, transcript, and speaker-labelled files are not available from this route.
- Because subtitles are burned in, viewers cannot switch them off or replace them in the exported video.
What it costs
Captioning costs 244 credits (~$1.93) at the creator's 15-second default duration setting. The charge follows the duration you set there, not your upload's length.

Frequently asked questions
- What input does the AI subtitle generator use?
- Upload a video with speech. Reviral transcribes that audio and keeps it in the newly rendered result.
- Does it support automatic subtitle translation?
- No translation control is promised on this page. The route transcribes the speech it detects rather than generating alternate-language tracks.
- Can I edit subtitle text before export?
- The linked legacy upload path does not expose a transcript editor, so inspect the completed render and correct the source workflow if needed.
- What subtitle styles can I select?
- Choose among 22 animated caption presets and place the text at the top, middle, or bottom.
- Will it identify different speakers?
- No. The subtitle workflow creates one word-timed transcript without automatic speaker names or diarisation.
- Can I export an SRT file?
- No. The deliverable is a video with subtitles permanently burned into the image, not a standalone subtitle file.
- How does subtitle pricing work?
- The creator charges from the duration selected in its settings, not by reading the length of the uploaded file; the live amount is shown before rendering.
