Video formats for mobile devices
For a long time, the mobile phone has ceased to be just a means of communication. At the moment, it is most often used as a camera, mp3 player, and video player.
If most users have no problem with the first and second, it is sometimes impossible to watch the video due to lack of compatibility with the required file format. Today, many pocket players are also equipped with support for video files, which are actually mpeg4 players, although they are often called mp3 out of habit.
The format problem is thought to be solved by special programs that allow you to change the video format, that is, convert it.
There are many programs for converting video files and the user has a fairly free choice. At your discretion, you can choose a program with the widest possible set of settings, or vice versa, some simple program that doesn’t even require installation. There is a choice and it is nice.
Popular video formats for mobile devices
So, here are some examples of the most popular video formats for mobile devices:
3gp (3GP);
AMR-NB or AAC-LC;
AVI;
MOV;
MP4, also known as MPEG-4;
Now it is worth discussing each of the formats in more detail.
3gp (3GP) is a video format developed specifically for third-generation phones, but it turned out to be so successful that it soon became the main format for mobile devices. 3gp saves the video as MPEG-4 or H.263. Audio is saved in formats
AMR-NB or AAC-LC. Video clips finished in 3gp format are small compared to other video formats, but unfortunately this greatly affects the quality (it is very low). If you suddenly see the 3gpp format, don’t be alarmed, this is the same 3gp.
AVI – Audio Video Interleave, literally translated is the interlacing of audio and video. This format was originally used on desktop computers, but with the development of processing power in phones and players, it migrated to mobile devices.
MOV – Better known as QuickTime, Apple Computer’s proprietary technology for playing digital video, sound, text, animation, music, and panoramic images in a variety of formats. This format is most common in Apple brand products such as iPod, iPhone, and others.
MP4, also known as MPEG-4, was conceived as a way to transfer streaming media data, primarily video, over low-bandwidth channels. Unexpectedly, it gained popularity among users, because it allowed to place feature films of an hour and a half to two in good quality on a single CD and exchange video files on the Internet.
What video size is right for your device? – everything is very simple, most devices play videos in full screen mode, which means it is better to create files similar to the screen resolution of your device.
As for me, I prefer the MP4 format. A good volume / quality ratio, reproduced on all devices of the class that I buy, it is easy to find on the Internet without the need for transcoding (I do not want to use a computer to download a movie to my smartphone, because a smartphone is for that and a smartphone to perform various operations and not involve other devices in action).
Disadvantages, advantages and more
Whether it is convenient to watch a video on the road can be debated indefinitely. However, every day more and more people appear on the train, plane and even in the minibus who like to spend time, not reading books or listening to music, but in front of a “blue” mobile screen. Want to join the ranks of mobile moviegoers, but don’t know how to make your communicator, PDA or smartphone “spin the movie”?
Let’s try to describe the benefits that a person who masters the art of pocket video gets. The first is mobility. To see a new blockbuster, for example, in the compartment of a train, it is not necessary to lug around a bulky laptop or, in general, a television. All you have to do is sit on your shelf and put on your headphones.
Since portable devices often have a slightly lower appetite for battery power than laptops, such a mobile “theater” can provide several hours of video viewing. The long road will no longer be boring.
There are also downsides to a mobile theater. For example, it is a relatively small screen that cannot be compared, for example, with the screen of a television or widescreen monitor. However, if you own a VGA device like the HTC Advantage X7500 (formerly known as HTC Athena), you won’t have to complain about the small
