MP4 is the most common video format on the web — used by YouTube, video editing apps, smartphones, and most recording software. To transcribe MP4 to text, LineaType handles the entire flow: extracts the audio internally, transcribes, and reviews the result automatically. You only upload the file.

The result serves two main purposes: generating SRT subtitles for the same video (with precise timing for use on YouTube, Vimeo, or video editors), and creating the text transcript that becomes a blog post, article, summary, or social media content. Automatic speaker identification labels each line — useful for interviews and conversation videos.

Process

How it works

Three steps. From MP4 video to clean text or SRT subtitles.

1

Upload the MP4 file

Drag and drop or click to select. Up to 150 MB per file — fits about 20 minutes of HD video. For longer files, compress or export just the audio.

2

Audio extraction + automatic transcription

The audio is extracted from the MP4 internally. The AI transcribes the audio and a second review layer fixes punctuation and removes filler.

3

Export as text or SRT subtitles

TXT, DOCX, PDF for use as text. SRT with precise timing to use as subtitles on YouTube, Vimeo, or in a video editor.

Also works with:
.mp4
.mov
.mkv
.avi
.webm
.mp3
.wav
.m4a

Frequently asked questions

150 MB per file. For reference: a 720p MP4 typically fits about 15–25 minutes; a 1080p MP4 fits 5–15 minutes depending on bitrate. For longer files, compress the video or export just the audio (MP3 of 1 hour ≈ 55 MB).
No. Resolution doesn't affect transcription — what matters is the audio quality inside the file. 720p, 1080p, 4K: all work the same.
Yes. The generated SRT file follows the universal subtitle standard. On YouTube, open the video panel, go to "Subtitles" and upload the SRT. For Vimeo, the path is similar.
On average, 2 to 5 minutes for a 10-minute MP4 — including audio extraction, transcription, and review. Time varies with file size and server load.
Yes, automatically. The engine detects distinct voices and labels each segment by speaker. Initially generic ("Speaker 1", "Speaker 2") — you can rename them.
Yes. Once the transcription is complete, you can export the same file as TXT, DOCX, PDF, and SRT without re-transcribing. Each format has its own export button on the platform.
