CED File

What are CED files and how to open them

Are you having problems opening a CED file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your CED files.

What is a CED file?

CED files have multiple uses, and JVC Video Data is one of them. Read more about the other uses further down the page.

JVC Video Data File

The CED file format was developed by JVC for their line of digital video cameras. This file format is used by the JVC recorder to store corrupted video data. These CED files are generated by the firmware of these JVC digital video recorders when there are issues with the memory card of the device. For example, if there is a problem with the memory card present in the JVC digital video recorder, then a .ced file will be created by the firmware of the device when users try to capture videos using the camera.

The raw video data that was recorded by the JVC camera is saved in a file with the .ced extension.

How to open CED files

Important: Different programs may use files with the CED file extension for different purposes, so unless you are sure which format your CED file is, you may need to try a few different programs.

While we have not verified the apps ourselves yet, our users have suggested eight different CED openers which you will find listed below.

All known file formats using extension .CED

While JVC Video Data File is a popular type of CED-file, we know of 2 different uses of the .CED file extension. Different software may use files with the same extension for different types of data.

EEGLAB Channel Data

EEGLAB channel data files store the spatial locations and labels of EEG electrodes together with their coordinate information, in several coordinate systems. They are used when analysing EEG data in EEGLAB (a MATLAB toolbox) to represent where each channel (sensor) is placed on the scalp. Such files are produced by EEGLAB itself (through its channel‐editing tools) or by users to define custom electrode layouts, and they are read by EEGLAB when importing or editing channel locations.

The file format is simple ASCII text (tab-separated values) listing one line per channel. Each line provides the channel number, the label (name), two‐dimensional polar coordinates (theta, radius), three‐dimensional Cartesian coordinates (X, Y, Z), and spherical coordinates (sph_theta: horizontal angle; sph_phi: elevation; sph_radius: distance from head centre). EEGLAB uses this data structure within its EEG.chanlocs field. These files enable plotting electrode positions (2D topoplot, 3D head plots), converting between coordinate systems, or matching channel labels to anatomical landmarks.

Various apps that use files with this extension

These apps are known to open certain types of CED files. Remember, different programs may use CED files for different purposes, so you may need to try out a few of them to be able to open your specific file.
