Scan mode. We have mentioned that video is actually a series of photos. Scan modes (include interlace and progressive) are the way of displaying these photos. Though most Digital SLR cameras are using progressive, but you need to know that many of them are played in the system of interlace. HD video (1920×1080) has two modes while 1280×720 video has only progressive.


Aspect ratio. Most photos taken by DSLR are 3×2 (1.5:1), which is some like the square. However, the HD video records 16×9 aspect ratio.


Compression. The aim of compressing is only one: decrease data rate and file size. You may have been familiar with it. While storing photos as JPEG, it is a way of lossy compression. There are many kinds of technology in JPEG and decrease the file size as well as image quality. Meanwhile, the RAW photo is a way of lossless compression. Though RAW video has been existed, the huge size keeps it from the area of digital video shooting.
