With the development of telecommunication systems, a large number of different options for storing and presenting digital information have appeared. There are many different video formats, each with its own special properties.
The choice of video format for your Nokia phone depends on the specific model. The most popular series of this phone mainly support MPEG4 and 3GPP formats. The MPEG4 format mainly reads files downloaded from the Internet, as well as those created by commercial companies. It provides good sound and picture quality and has the most optimal ratio of quality and file size of content content. Recently Nokia models use MPEG4 as the main recording format, the standard resolution of which is 352x288, 640x480. Almost all Nokia models are supported: C6, C5, E51, E50, E55, E52, E61, E60, E63, E62, E66, E65, E71, E70, E90, E75, N72, N71, N75, N73, N77, N76, N79, N78, N81, N80, N85, N82, N90, N86, N93, N92, N96, N95, N800, N97, X3, N900, 53x, X6, 57x, 56x, 5130, 71x, 5220, 5200, 5230, 5228, 5800, 5530, 6760, 6700, 7705, 7020 and others. The 3GPP format is commonly used to play back recordings made on a mobile phone. The format of this type is characterized by a lower resolution, but it can record much more information in terms of volume than MPEG4. The usual resolutions for this format are 176x144 and 128x96. AVI video format is better than 3GPP, but inferior to MPEG4. AVI contains encoded video and audio tracks, just like MPEG4. But if the video tracks in both formats are the same - mp4, then the audio is different: in MPEG4 - aac-lc, and in AVI - mp3. According to its technical characteristics, aac-lc compresses the original size much better than mp3. At the same time, the quality of aac-lc is not inferior to mp3. In addition, the MPEG4 format has many more features than AVI, such as online playback. Many Nokia phones support FLV, which is not a video format but is called a media container. It is also often used in phones of this brand. Nokia has released many utilities for converting video files from one format to another, an example of such a program is "Multimedia Converter", or Free Video to Nokia Phones, which convert the following input file formats to MPEG4: *.ts; *.avi; *.mkv; *.ivf; *.ogv; *.div; *.rmvb; *.divx; *.rv; *.mpg; *.rmm; *.mpeg; *.rm; *.mpe; *.amv; *.mp4; *.f4v; *.m4v; *.flv; *.webm; *.dvr-ms; *.wmv; *.3g2; *.asf; *.3gp; *.mov; *.3gpp; *.qt; *.3gp2; *.mts; *.dat; *.m2t; *.vro; *.m2ts; *.tod; *.mod. The user manual for any Nokia phone model must indicate which video format is supported by this model. If you lose the manual, you can easily download it from the Internet, or find it on the official website Nokia.com.
