Translate English Video to Portuguese

Upload your English video file and our AI transcribes the speech first — converting the English audio to text with speaker labels and timestamps. Once the English transcript is ready, select Portuguese as your target language to translate. Review the Portuguese translation, edit if needed, and export as SRT subtitles or a plain text file in just a few clicks.

Yes — our AI video translator delivers 98%+ accuracy on English transcription and context-aware Portuguese translation. It handles different English dialects, regional accents, and multiple speakers. The AI preserves meaning and tone rather than producing word-for-word output.

Any format your English video is saved in — MP4, MOV, AVI, MKV, WebM, FLV, and more. There is no need to convert video files beforehand. Upload the original English video and the translator handles the rest, producing your Portuguese transcript and subtitles directly.

PrismaScribe focuses on accurate transcription and translation rather than AI dubbing, voice cloning, or AI voiceover generation. Instead of replacing the original English audio with synthetic voiceover or lip-synced dubbing, we deliver precise Portuguese subtitles and translated transcripts. This approach preserves the authenticity of the original English video while making the content fully accessible in Portuguese.
