Transcribe MP4 to Text

MPEG-4 Part 14 video to an accurate transcript

To convert an MP4 to text, upload your .mp4 video to LiteScribe and it transcribes the audio track into text with speaker labels and timestamps. MP4 is the default for screen recordings, webinars, and phone video, and only the audio is needed for a transcript, so the desktop app can extract it locally to skip a huge upload. Free on web, desktop, mobile, and Chrome.

What is MP4?

MP4 is the most common video container on the internet. It usually holds H.264 video alongside an AAC audio track, and it is what most phones, screen recorders, webinar tools, and cameras produce by default. For transcription, only the audio track inside the MP4 matters; the video frames are along for the ride.

File size: A one-hour 1080p MP4 is often 1 to 3 GB, the vast majority of which is video; the speech you actually want to transcribe is usually under 100 MB of audio.

Transcription tip for MP4

An MP4 carries heavy video data you do not need for a transcript. LiteScribe transcribes the audio track inside the container, and the desktop app can extract just the audio locally before upload so you are not sending gigabytes of video for a text result.

Why transcribe MP4 video with LiteScribe

Audio from video

LiteScribe reads the audio track inside the MP4, so the video frames do not get in the way of the words.

Skip the huge upload

On desktop, extract just the audio locally so you send under 100 MB instead of a multi-gigabyte video.

Speaker labels

Diarization labels each voice, ideal for meeting, webinar, and interview MP4 recordings.

Subtitles included

Export SRT to caption the original MP4, or DOCX and PDF for a written record.

How to convert MP4 to text

1
Add your MP4 file
Drag and drop your MP4 video file into LiteScribe, choose it from your device, or paste a link. MP4 uploads directly with no conversion step, and large files use resumable upload so a dropped connection does not lose your progress.
2
Pull the speech out of the video
LiteScribe reads the audio track inside the MP4 container and transcribes the speech. The desktop app can extract just the audio locally first, so you upload a small audio file instead of a large video when you only need the words.
3
Review, label, and ask AI
Read the transcript with each speaker labeled and every line timestamped. Rename speakers, fix any names or jargon, then ask the built-in AI to summarise, pull action items, or answer questions about what was said.
4
Export the text
Download your transcript as DOCX, PDF, or plain TXT, or export SRT subtitles to caption the original MP4 video. Copy any section straight into your notes, documents, or content.

LiteScribe accepts MP4 directly

There is no separate conversion tool to run first. LiteScribe accepts MP4 alongside MP3, WAV, M4A, AAC, OGG, OPUS, WebM, FLAC, WMA and the common video containers MP4, MOV, MKV, and AVI, on the web app, the desktop app, mobile, and the Chrome extension. Upload the file as it came off your device, or record live and let LiteScribe capture it for you, and the transcript comes back with speaker labels, timestamps, automatic punctuation, and an AI summary.
