Understanding M2V files

What is a M2V file?

MPEG-2 video-only stream for DVD authoring

M2V files are usually raw video files and thus, will not have any audio to be transcribed. They are normally designed to be multiplexed (also known as ‘muxed’) where audio data and other streams (including subtitles) are added before authoring (creation of a master or a DVD master). Thus, while you won’t be transcribing M2V files directly, you can easily transcribe with Sonix the audio stream that you will mux with the M2V file to create fast, accurate subtitle SRT files.
M2V files are usually an extracted video-only version of a MPEG-2 file, but they can also sometimes contain audio files. They are also commonly seen with M2As, AIFs or WAV audio files before authoring.
