Convert WEBM to JPG

Like the MKV file extension, the WEBM royalty-free extension is developed by various online parties such as Google. It is a freeware offering streaming of online video content. It was first developed in 2010. By using the HTML5 version of YouTube, one can watch videos encoded in WEBM.

Encoding and decoding in open-source WEBM video format are possible while using the ffvp8 software or libvpx from the Google support. When it comes to the Android, support a version of 2.3 (Gingerbread) and above, allowing playback of WEBM format can be used for encoding and decoding. Back in 2001, using Rockchip, a full hardware implementation of 1080p VO8 encoding was made possible. The video element of the file is encoded using VP8 video codec, and the audio component of the file is encoded using the Vorbis audio codec. It provides open video compression for HTML5 videos, and most major web browsers support WebM as a part of HTML5 video delivery. However, some programs like Quicktime and browsers like Internet Explorer and Safari do not have native WebM support. Fortunately, the Google WebM Project Team released plugins for Internet Explorer and Safari in 2011 to allow WebM files' playback through the standard HTML5 video tag.

.jpg

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.
