MP4 to Text Converter — Transcribe MP4 Video Online

Upload your MP4 file to NovaScribe, select your language, and click transcribe. Results are ready in 2–5 minutes. You can then edit the transcript in the browser and export as TXT, DOCX, PDF, SRT, or VTT. No software installation required.

NovaScribe offers a free trial for new users. Free tiers are available from several services: TurboScribe allows 3 free MP4 files per day, Notta provides 200 minutes/month free, and Otter.ai gives 300 minutes/month free. For regular use, NovaScribe’s paid plans start at $2/month for 200 minutes.

AI transcription processes MP4 files at roughly 10–30x real-time speed. A 1-hour MP4 video is typically transcribed in 2–5 minutes. File upload time depends on your internet connection and file size. Human transcription of the same 1-hour video would take 4–6 hours.

File size limits vary by service. Most AI transcription services accept MP4 files up to 500MB–2GB per upload. Duration limits typically range from 2–10 hours per file. For very large files (broadcast footage, long webinars), check the specific limits before uploading or compress the video first.

AI transcription of MP4 video reaches 95–98% accuracy for clear video recordings with a single speaker and standard audio. For videos with multiple speakers, background noise, or non-English content, accuracy typically falls to 80–95%. Zoom recordings, lecture recordings, and interview footage generally transcribe very accurately. Live event recordings or videos with music/ambient sound produce lower accuracy.

Yes — NovaScribe exports transcripts as SRT files with accurate timestamps, ready to upload directly to YouTube, Vimeo, or any video platform. The SRT file contains timed text that matches your video frame-by-frame. You can edit the subtitles in NovaScribe’s editor before downloading.

Yes. MP4 files from Zoom cloud recordings, Loom, OBS, Camtasia, and other screen recording tools all work with NovaScribe. For Zoom recordings, export the meeting as an MP4 from Zoom’s cloud recording section, then upload directly to NovaScribe. Screen recordings typically have clear system audio and transcribe at high accuracy.

NovaScribe supports all major video formats: MP4, MOV, MKV, AVI, WEBM, MPEG, M4V, and WMV. It also accepts audio-only formats: MP3, WAV, M4A, AAC, OGG, and FLAC. You don’t need to convert your file first — upload any supported format directly.
