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.

My first trial was a video interview with a woman with an Eastern European accent, and I thought there was no way your system would render a good transcription—but it was amazingly accurate!
