MP4 Transcription features

SRT & VTT Subtitle Export

Generates timestamped SRT and VTT subtitle files from your MP4 - ready to upload to YouTube, Vimeo, or any LMS platform.

Millisecond Timestamps

Captions and transcript timestamps sync precisely with the video audio, requiring minimal manual correction.

Speaker Diarization

Automatically identifies and labels each unique speaker in the MP4 - ideal for webinars, interviews, and multi-person videos.

Flexible Output

Download the transcript and subtitle files as TXT, DOCX, SRT, and VTT simultaneously from the same upload.

Wide Codec Support

Handles all common MP4 codecs (H.264, H.265, AV1) and container variants without pre-conversion.

Secure Processing

Files are encrypted in transit and at rest.

Why Choose Our MP4 Transcription Service?

Transcribe an MP4 video and get subtitles from the same upload. ForgeFile takes the audio track out of the MP4 container (ISO/IEC 14496-14), transcribes the speech and returns a timestamped transcript together with SRT and VTT subtitle files.

For YouTube creators, educators and social media producers: upload a recording from OBS, Zoom or your phone, then attach the SRT or VTT file to your player or import it into DaVinci Resolve, Adobe Premiere or Final Cut Pro.

MP4 Video Workflows

  • YouTube and Vimeo captions - Download an SRT file and upload it in the creator studio.
  • Screen recordings and webinars - Turn OBS, Loom and Zoom recordings into searchable text.
  • Social video subtitles - Caption short clips for TikTok, Instagram Reels and LinkedIn.
  • Course videos - Add WebVTT caption tracks to lessons in Canvas, Blackboard or Moodle.

What You Get from an MP4

  • Only the audio is processed - The video stream is not re-encoded, so a long recording does not have to be converted first.
  • Speaker labels - Turn on speaker detection to mark who is talking in the transcript.
  • Several export formats - Plain text, Word DOCX, JSON and SRT/VTT subtitles.

The MP4 file format is documented by the Library of Congress digital format sustainability project.

Frequently Asked Questions - MP4 Transcription

What video formats are supported?

MP4 is the primary supported format for this service. For AVI, MOV, MKV, and other formats, see our Video Transcription service which handles all common video containers.

Can I generate YouTube subtitles from an MP4 file?

Yes. After transcription, you receive an SRT file with millisecond-precise timestamps. Upload it directly to YouTube's subtitle manager to get accurate closed captions - no manual editing required.

Does it identify different speakers in the video?

Yes. Speaker diarization detects and labels each unique speaker (Speaker 1, Speaker 2, etc.) throughout the video. Works best for 2–6 distinct speakers with clear audio.

Is the video kept private?

Files are encrypted in transit and at rest. How long they are kept depends on your plan.

Can I download both SRT and VTT from the same upload?

Yes. Both SRT and VTT subtitle files are generated simultaneously and available for download from the same result page.

What languages are supported?

Select the correct language before uploading for best accuracy. Check language support before submitting your file.
