YouTube Video size

Google Corporation sets a number of requirements and offers many recommendations on video format, codec, bit rate, and resolution to upload to YouTube servers. Clips should be added in the highest resolution available, ensuring high image quality when viewed on large screens, flexibility when converting or rendering after editing.

Videos intended for rental should have a frame size of at least 1080p (Full HD) and an aspect ratio of 16 to 9, the parameters of most modern monitors. For commercial videos where you plan to insert ads, there are no frame size restrictions. However, you should not upload files with frame sizes below 720p at 16: 9 and 480p at 4: 3. With low quality, users with large monitors will find it uncomfortable to watch video footage, they may miss its content.

It is worth knowing that after downloading the video, YouTube always re-converts the material to optimize the playback quality.

The service will not read it. At the same time, a file of a certain format may be compatible with a video hosting service, but the video codec used to encode it is not. To avoid duplicate work, convert or save your work in the following formats:

The following types of files can be used as an audio track:

Video size (resolution and aspect ratio)
The size of a video to upload to YouTube depends on the way it is viewed: in an Internet browser, an application for the Android or iOS mobile platform, a third-party player, and the format: classic horizontal or vertical, shot on a mobile device. The player for mobile platforms adapts to the dimensions of the video, regardless of its orientation, trying to fill the maximum area of ​​the screen with useful content. In this case, the frame is neither stretched nor compressed.

The YouTube video player window has a length-to-height ratio of 16 to 9. Deviating from the royalties is not recommended; this is a classic format, the most widespread in the world.

When playing videos with different settings, gray or white bars may appear in the corners or at the top and bottom of the screen, depending on the active theme.

How does 3GP work?

How does 3GP work?

With the advancement of technology, certain inventions that were once innovative are often forgotten. An example is the third generation of cellular technology known as 3G and currently replaced by 4G. Among its different characteristics, this technology brought with it the answer to the problem of how to view videos on smartphones. To be able to understand the way they did it you must know how 3GP works.

3GP comes from the association of several telecommunications groups, better known as 3GPP (Third Generation Partnership Project). This is a multimedia container format created for smartphones with 3G technology. However, it can also be used in some devices with 2G and 4G technology.

3GP is capable of containing files with the following video formats: H.263, PEG-4 and MPEG-4 Part 10 (AVC / H.264). In the case of audio tracks, it supports the following formats: AAC-LC, HE-AAC V1, HE-AAC V2, AMR-WB, AMR-WB + and AMR-NB. On the other hand, it offers a video resolution of 176 × 144 for cell phones that only support the 3GP format. On cell phones with other formats such as MP4, it offers a resolution of 320 × 240.

How does 3GP work?

To understand how 3GP works we must first go back to the need for which it arose. A few years ago the slow internet connection and the large size of multimedia files made it difficult to watch videos from a Smartphone. Because of this, 3GPP focused on creating a means to solve this problem, with the 3GP format emerging.

For their creation they were based on the MP4 format, which was created for PC. So 3GP is a less bulky simplification of that format. It was designed to reduce or decrease the storage bandwidth requirements, in order to adapt them to cell phones.

However, its small size is not the only important aspect of its functionality. Making use of 3G technology and the advances in network connection that it produced, this format allowed the transmission at high speeds of any multimedia medium.

Qualities of 3GP

Among the different characteristics of this format we have the following: the inclusion of a text, which can be opened using any type of text editor such as Notepad. Outside of 3G phones, 3GP files can be played in Windows Media Player, VLC Media Player, QuickTime and Media Player Classic. It is also compatible with playback media from the PlayStation 3 and Nintendo DSi consoles.

This format was created for phones with GSM technology, while its variation called 3G2 is used in CDMA technologies. Another of its qualities is that it does not require a 3G gadget to enable this format before viewing the file.

However, despite these design advantages, it also has certain disadvantages. The main one is that when compressing audio and video, the quality of these decreases compared to other formats. Also, it is not possible to change the file’s .3gp extension to another format, unless an actual file format conversion is performed.
