Upload an MP4 File, Get the Summary and Transcript
MP4 summarizer takes a video file you already have and turns it into a written summary you can read in a couple of minutes. Upload the file, and ScreenApp transcribes the audio, labels the speakers, splits the video into chapters, and writes the summary with timestamps that jump back to the moment in the video.
You get a document, not a wall of text: an overview, chapters with start times, and quotes attributed to who said them. The full transcript stays attached, so you can also ask questions about the video and get answers that point to the timestamp. Here is a real example: a sample summary PDF ScreenApp produced from an interview, and the same output as a Word file.
What you get with every MP4 upload:
- A transcript with speaker labels and timestamps, in 100+ languages, auto-detected
- chapters with timestamps
- AI reads video frames, not just the audio, so slides and on-screen text make it into the notes
- AI chat with any recording
- Exports as PDF, DOCX, TXT, SRT and VTT
- Free plan: 2 transcriptions of recordings up to 45 minutes each, with AI chat on it
Large MP4 uploads process the same way, since the app has no set file size limit. MOV, AVI, MKV, and WebM follow the identical pipeline, so the file format your camera or screen recorder happened to save in does not matter.
How to Summarize an MP4 File
- Upload your MP4 file: Drag the file into ScreenApp. The app has no set file size limit. You can also paste a public video link into the AI video summarizer if you do not have the file downloaded yet.
- Let it process: The audio is transcribed, speakers are labelled, and the video is split into chapters. AI reads video frames, not just the audio.
- Read, ask, export: Read the summary, click a timestamp to jump to that moment in the video, or ask a question about it. Export as PDF, DOCX, TXT, SRT and VTT.
Summary quality follows transcript quality. A screen recording or interview with a clear microphone transcribes well; a phone recording of a room with side conversations will have gaps. See how we measure accuracy.

Who Uses an MP4 Summarizer
Students upload lecture recordings and course videos to get a transcript and notes they can search before an exam, instead of scrubbing back through the file to find one point.
Professionals summarize recorded meetings and presentations saved as MP4, pulling out decisions and action items without rewatching the whole call.
Content creators generate transcripts to speed up captioning and social posts. Many also use the transcript for text-based video editing in tools like Descript, where you edit the video by editing the transcript.
Researchers process interview footage saved locally, identifying themes and pulling quotes with a timestamp across multiple files.
Marketers review competitor video files and recorded demos without watching the whole thing, and ask the AI chat what was said about a specific topic.
If your file is audio only, such as MP3, WAV, or M4A, the AI audio summarizer produces the same kind of summary.
