Understanding MP4 files

What is a MP4 file?

Universal video standard for web, mobile, and streaming

An MP4 file is also known as a MPEG-4 Part 14 multimedia container. MP4 files were developed by the Moving Picture Experts Group (MPED). WIth an MP4 File, there are separate compression algorithms for the audio and video tracks. Typically, video is compressed with the MPEG-4 codec and the audio is compressed using the AAC codec (which is the same codec used in AAC files). Most MP4 files are downloaded from Apple’s iTunes STore since most of the media downloaded from the store is downloaded in this format. The MP4 format is also used for Internet streaming video.

Common Questions

Everything about MP4 to text

Can Sonix transcribe MP4 video files?

Yes! MP4 is Sonix's most commonly transcribed format. We extract the audio track (typically AAC encoded) and transcribe it with industry-leading accuracy. Works for everything from YouTube videos to smartphone recordings to professional productions.

How long does it take to transcribe an MP4 video?

Sonix transcribes MP4 files at approximately 10x real-time speed. A 30-minute video transcribes in about 3 minutes. Upload time depends on file size - 1080p videos are larger than 720p but transcribe at the same speed.

Can I create subtitles from my MP4 transcription?

Absolutely! After transcribing your MP4, export the transcript as SRT or VTT subtitle files with perfect timing synchronization. Embed these subtitles back into your video or upload separately to platforms like YouTube.

Does video resolution affect MP4 transcription?

Video resolution (720p, 1080p, 4K) doesn't affect transcription accuracy - we're transcribing the audio track. Higher resolution videos have larger file sizes but the audio quality is typically the same.

Can I transcribe MP4 screen recordings?

Yes! Screen recordings with narration transcribe excellently. Sonix is perfect for transcribing tutorials, software demos, presentations, and online course content.

What about MP4 files with multiple audio tracks?

MP4 files can contain multiple audio tracks (different languages, commentary). Sonix transcribes the primary audio track. If you need a specific track, extract it first using video editing software.
