You can also use various converters to convert videos to MP4 file formats. Which other formats MP4 can be converted into and why MP4 is widely used as a video file format because of the efficient video compression scheme that prevents data loss when converting. Some of the popular video formats are: 1. MIME type. Main program. JPEG — is a popular graphic file format, which is characterized by a high degree of compression, which leads to a decrease in image quality.
It uses the technology of encoding smooth color renditions, providing the ability to reduce the amount of data frequently during the image 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 JPEG 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 to compress drawings and various graphics since a big difference between several near located pixels provokes visible artifacts. The procedure for compressing the digital images in JPEG format is carried out in several stages.
First, the photo is transformed into a color space YCbCr. 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 file compression ratio is in the range from to
