What is a carved video?
It focuses on carving video files encoded using the MPEG video format. … File carving is the process of extracting file fragments from a byte stream without file system information. This technique is mostly used to recover data from unallocated space on a hard disk.
What are two advantages and disadvantages of the raw format?
3. What are two advantages and disadvantages of the raw format? Advantages: faster data transfer speeds, ignores minor data errors, and most forensics analysis tools can read it.
What is the biggest disadvantage of the RAW file format?
Disadvantages of RAW Image FormatRAW files use loseless compression so they take significantly more space than JPEG files which use lossy compression.RAW files require processing before you can view them as images – this workflow is not convenient for the casual storing and sharing of files.More items…
What is RAW vs JPEG?
Raw offers more creative processing flexibility The JPEG processing applied by the camera is designed to produce a good-looking image right out of the camera, and this processing cannot be undone. A raw file, on the other hand, is processed by you; so you can decide how the image will look.
