Use Portuguese audio as the source
Select Portuguese for a video spoken in Portuguese. AIVideoCaption generates timed text from that audio and lets you edit it before you download an MP4 or SRT file.
If the voice is in English and you need Portuguese subtitles, that is translation—a different task from the transcription offered here. The distinction helps you choose the right workflow before you upload.
02 / A human review
Keep the speaker’s local words
Portuguese is spoken in different regions. Do not rewrite a familiar local phrase into another variety just because it looks more common in an automated draft. Listen to the clip, retain the speaker’s wording, and check accents, names and place names.
“Foi isso que a pessoa disse?”
Keep local terms consistent throughout the video.
For Brazilian or European Portuguese, judge a real clip from your audience before relying on any accuracy claim. The language option is Portuguese; this page does not promise equal performance across regional varieties.

06 / Questions
Portuguese subtitle questions
Does this work with Brazilian and European Portuguese?
Portuguese is selectable, but results can vary by speaker, region and recording. Review a clip from your own audience before publishing.
Can I edit accents and local words?
Yes. The generated captions are editable before export.
Can I add Portuguese subtitles to an English video?
No. This workflow transcribes Portuguese speech; it does not translate English speech into Portuguese.
03 / Reels and Shorts
Let the spoken point lead the visual style
A short clip needs captions that remain readable over changing footage. Start with a calm style for an explanation, or highlight one meaningful word in a lively Reel. Check the preview at mobile size, especially where the platform adds its own buttons and text.
