Besides, to play recorded videos more easily, you can convert the videos to a common format with the good video converter:

What Are CPI Files

Q1: I have some video files with a ".cpi" extension which I am not able to open nor view. How can I open these files/videos? Is it possible to convert CPI to MP4 with a CPI file converter or something like it?

Q2: Hi, I have recorded some videos with my Sony Alpha 6000 camera and there are CPI files along with MTS files. But I can’t access these CPI files somehow. Any suggestion?

A CPI file is a descriptive file used to describe an AVCHD or MTS video stream and it contains the related metadata including frame rate, frames per second, and aspect ratio. CPI files are primarily created by Sony and Panasonic associated with the AVCHD video format and it can be found in directory PRIVATE > AVCHD > BDMV > CLIPINF. As CPI files are video clip information files without any video or audio data contained, you can’t directly play it with a media player, let alone convert CPI to a video format. But if you want to view the clip information, there are some tools for you to open CPI files. Read on!
