Open CED File
The CED extension file or format is fundamentally related to the JVC company, because it was developed by them to store corrupted video data in case of any problem with a memory card (its damage or loss) in some models of digital cameras.
CED extension files are related to management information created by certain JVC AVCHD camcorder devices (mainly SD-based).
AVCHD is a proprietary, heavily BluRay-based standard that includes codecs and file structures for high-definition video recording and storage.
These CED format and extension files may contain (but not necessarily) a usable stream of video data, depending on the reason for the error.
