What is a CLPI file?
A .CLPI file is a Blu-ray Clip Information File. The Blu-ray Disc Association created this format for Blu-ray discs. It does not contain actual video data. Instead, it holds metadata for a corresponding .M2TS video stream. This metadata includes timecodes, frame rates, and resolution details.
How to open CLPI files?
Usually, you do not need to open .CLPI files manually. They live inside the `BDMV/CLIPINF` directory of a Blu-ray disc. When you play a movie, software like CyberLink PowerDVD or VLC media player reads the .CLPI file in the background.
If you want to inspect the data inside a .CLPI file, you can use specialized authoring tools like BDedit. Because a file extension can sometimes have multiple meanings, viewer.online/clpi analyzes .CLPI files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Summary
viewer.online/clpi directly opens and previews .CLPI files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
