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

Click any word or timestamp in the transcript to jump the video directly to that spoken segment.

Privacy Secured

Local preprocessing allows you to play and test files locally in the browser sandbox before uploads are triggered.

Inline Studio Editor

Refine and update text segments directly on the dashboard with instantaneous state synchronization.

Hardsub a link in 3 steps

Paste, edit, render. Done.

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.

Hardsub engine FAQs

How is this different from soft subs?+

Soft subs sit in a separate track that some platforms ignore or strip. Hardsubs are part of the picture — they survive every re-upload.

Can I style the captions?+

Yes — font, size, weight, colour per speaker, and outline thickness are all configurable before the render starts.

Where does the rendering happen?+

On Pxlify's cloud renderers, not your machine. Even a long episode finishes faster than a local FFmpeg burn.

Will the engine handle interview-style multi-speaker video?+

Yes. Speaker diarization assigns colours automatically, so two-person and three-person conversations stay readable on screen.
