In digital forensics, to recover the damaged or altered video file plays a crucial role in probing for evidences to determine a criminal case. File recovery techniques make use of the file system information that remains after deletion of a file. By using this information, many files can be recovered. For this technique to work, the file system information needs to be correct. If not, the files can’t be recovered. If a system is formatted, the file recovery techniques will not work either. Carving deals with the raw data on the media and doesn’t use the file system structure during its process. Although carving doesn’t care about which file system is used to store the files, it could be very helpful to understand how a specific file system works. This paper presents a study of recovery and carving technique of a corrupted video file using the specifications of a codec used to encode the video data.
