How to convert .ifo files to MP4? Or how to convert .ifo to MKV, MOV? We often see these questions in many question-answering platforms and forums. In fact, there are some misunderstandings about the IFO file. Here's a simple correction.
First, the IFO file itself doesn't store actual video and audio data. Instead, it is a DVD Information File format which provides information about the contents of the disc, telling DVD player what to display and enabling users to navigate.
Second, IFO files are useless without the corresponding VOB files which contain the actual videos. But the structure of DVD's directory is incomplete without IFO files and the movie can't be played normally in DVD players.
So, when we are talking about converting .ifo files, it usually refers to the entire DVD folder (Video_TS) that contains all the .ifo, .bup, and .vob files. Next, let's learn how to convert IFO file to MP4.
