Whisper Speech Model

Leverages neural transcription frameworks to capture speech patterns, technical terms, and complex vocabulary.

Multi-Format Exports

Export to SRT, WebVTT, Advanced SSA (.ass), JSON, Word (.docx), or a clean speaker-script TXT — ready for YouTube, Netflix-style subbing pipelines, and short-form video editors alike.

Interactive Playback

Export word-level JSON in 3 steps

Upload, transcribe, download JSON.

01

Upload your video

Drag in a local file (.mp4, .webm, .mov) or pick an existing recording from your library.

02

Auto-generate timestamps

Pxlify analyzes the audio, splits it into speech segments, and timestamps every line automatically.

03

Refine & export

Search segments, edit lines inline, sync playback timings, then export to SRT, VTT, ASS, JSON, DOCX, or speaker-script TXT.

Word-level JSON FAQs

What does the JSON schema look like?+

Top-level title/language/exportedAt fields, plus a segments[] array (line-level cues) and a words[] array with per-word start/end and speaker.

Can I feed the JSON into Premiere or Resolve?+

Yes — most editor importers consume the JSON directly, or you can convert it with the included schema reference.

Are timestamps in seconds or milliseconds?+

Seconds as floats with millisecond resolution (e.g. 12.345). Matches the Whisper output convention.

Does the JSON export include speaker labels?+

Yes. Each segment and each word carries a speaker key.
