Windows Media Video (WMV) is a video format and is a part of Advanced Systems Format (asf) container. Microsoft developed this format. WMV files can be facilitated by a variety of Operating Systems such as Mac as well as the PC. A few WMV files also have the digits right management (DRM) protection, so unauthorized can't make copies of the recordings, basically the ones purchased from an online store.

The exclusive codecs developed by Microsoft can be obtained while a WMV file is compressed. Users can use Windows Media Video 9 Professional. It allows them to play their respective file at resolutions surpassing 300,000 pixels (having a screen resolution as low as 528x576) with an exceptional bit rate of 1000 Kbit/s. The high definition abilities make WMV files an ideal choice for HD DVD and Blu-ray disks. WMV 9 format is the one you should be looking for, and it is also comparable to H.264 Main and High Profile. It does not support various activities, such as multiple reference frames and context-adaptive binary arithmetic coding (CABAC). Lower bit-rates can reveal the differences between WMV and its competitors.

JPG – is a popular graphic format characterized by a high image compression rate, which leads to a decrease in image quality. It uses the technology of encoding smooth color renditions, providing the ability to frequently reduce the amount of data during the image's recording. Because of the small size, it is requested by the owners of websites, allowing you to save the traffic effectively. It is also frequently used in memory cards of digital video cameras. The JPG algorithm is optimally suitable for compressing photographs and pictures in which realistic scenes with little contrast of colors are present. It is not recommended to use this format for compression of drawings and various kinds of graphics. A strong contrast between several near located pixels provokes the appearance of visible artifacts.

The procedure for compressing the digital images in JPG format is carried out in several stages. First, the photo is transformed into a color space YCbCr, and then it is divided into squares to determine the upper range of the color spectrum. Finally, the colors and brightness are coded. JPEG uses a "lossy" compression system and discrete cosine transform technology. The format acts simultaneously as the standard of ISO and the International Telecommunication Union. The file compression ratio is in the range from 10:1 to 100:1. In this case, the reduction in image quality can vary from insignificant to substantial.
