CPI to TXT Converter

CPI to TXT Conversion Explained

Converting a .CPI (AVCHD Clip Information) file to a .TXT (Plain Text) file changes binary video metadata into human-readable text. People convert .CPI to .TXT to read camera settings, timestamps, and recording data without needing specialized video software.

You gain readability and searchability. You lose the binary structure required by video editors to link the metadata to the actual video file.

Warning: This conversion is a bad idea if you plan to edit the associated video. If you convert .CPI to .TXT and delete the original .CPI file, your AVCHD video files (.MTS or .M2TS) will lose their metadata link in non-linear editing (NLE) systems. .CPI files do not contain video, audio, or subtitles. Converting them will not generate a transcript of spoken words.

Typical Tasks and Users

• Data Wranglers: Extracting camera metadata on set to create readable logs of frame rates, resolutions, and timecodes.
• Digital Archivists: Storing video metadata alongside raw video files in a universally readable format for long-term preservation.
• Videographers: Debugging camera recording issues by reviewing the exact technical parameters saved by the camera during a shoot.

Software & Tool Support

Standard text editors will display gibberish if you try to open a raw .CPI file directly. To read or convert the data, you need specific tools:

• ExifTool: A free, powerful command-line application that can read .CPI binary data and export the metadata to a .TXT file.
• MediaInfo: A free utility that analyzes video files and their associated clip information, allowing users to export the technical data as plain text.
• Sony Catalyst Browse: Official, free software for viewing AVCHD folder structures and reading .CPI metadata.
• Text Editors: Any basic editor like Notepad++ or Apple TextEdit can open the resulting .TXT file after conversion.

Pros and Cons of the Conversion

Pros:

• Universal Compatibility: Any device, operating system, or basic application can open a .TXT file.
• Searchability: You can easily search a text file for specific timecodes or camera settings.
• Transparency: Hidden binary data becomes visible and easy to audit.

Cons:

• Breaks AVCHD Structure: Video editors like Adobe Premiere Pro or DaVinci Resolve cannot read .TXT files to sync clip metadata.
• One-Way Process: You cannot easily convert a .TXT file back into a working binary .CPI file.
• No Media Content: Users often mistakenly believe this conversion will yield video transcripts. It only yields technical metadata.

Conversion Difficulties & Why Convert.Guru

The main technical problem in this conversion is binary parsing. .CPI is a proprietary binary format used by Sony, Panasonic, and Canon. Simply renaming the file extension from .CPI to .TXT corrupts the file. A proper conversion requires a tool to parse the binary headers, extract specific metadata fields (like framerate, aspect ratio, and timecode), and map them into a structured text layout.

Convert.Guru handles this binary parsing automatically. It reads the proprietary AVCHD headers, extracts the exact metadata fields, and outputs a clean, readable .TXT file. This eliminates the need to install command-line tools or write custom extraction scripts.

CPI vs. TXT: What is the better choice?

Which format should you choose?

Choose .CPI when you are keeping the original AVCHD folder structure intact for video editing, color grading, or playback on the original camera. Do not alter or remove these files from their native CLIPINF folder.

Choose .TXT when you need to log, share, or archive the technical metadata for human review.

Avoid this conversion entirely if you are looking for a text transcript of the audio in your video. You must use speech-to-text software on the actual .MTS video file for that task.

Conclusion

Converting .CPI to .TXT makes sense only when you need to extract and read technical camera metadata outside of a video editing environment. The biggest limitation to watch for is the destruction of the AVCHD folder structure; always keep your original .CPI files if you plan to edit the footage. Convert.Guru is a reliable choice for this exact conversion because it accurately parses complex binary video metadata into clean, universally readable text without requiring specialized software.
