3gp is a video format file.
3GP (3GPP file format) is a format defined by the 3rd Generation Partnership Project (3GPP) for 3G UMTS multimedia services The multimedia container format is a video encoding container format for 3G streaming media. It is mainly used in 3G mobile phones, but can also be played on some 2G and 4G mobile phones.

3GP is a common video format and a simplified version of the MPEG-4 Part 14 (MP4) format, which reduces storage space and Lower bandwidth requirements allow the limited storage space on mobile phones to be used. 3GP supports multiple types of video files (MPEG-4 Part 2, H.263-based converter, MPEG-410 part) as well as multiple audio file formats (AMR technology for notebooks, AAC-LC, AMR-WB, and AMR-WB). 3GP file transfers always occur in a specific order - the largest and most significant bytes of information are always transferred first.
Technical Specifications
3GP is defined in the technical specifications of ETSI 3GPP. 3GP is for the video, related voice// A file format defined by audio media type and timed text.
3GP format video supports two resolutions: resolution 320×240, suitable for all mobile phones on the market that support 3GP format; resolution 352x288 (maximum resolution), clearer, suitable for various mobile phones, video playback device.
3GP codec
3GP file format is saved using MPEG-4 Part 2 or H.263 or MPEG-4 Part 10 (AVC/H.264) encoding standard Video stream, save audio stream using AMR-NB, AMR-WB, AMR-WB, AAC-LC, HE-AAC v1 or enhanced aacPlus (HE-AAC v2) encoding. 3GPP allows the use of AMR and H.263 for encoding and decoding in the ISO basic media file format (MPEG-4 Part 12), because 3GPP specifies the use of sample entries (Sample Entry) and template fields in the ISO basic media file format, and at the same time A new box defining codec references. For code points in the ISO base media file format ("MP4 family" files), these extended features are registered through a registration authority. For the storage of MPEG-4 media proprietary information in 3GP files, the 3GP regulations refer to the MP4 and AVC file formats and are also based on the ISO basic media file format. Among the ISO base media file formats, the MP4 and AVC file format specifications describe the usage of MPEG-4 content.
All 3GP files are big-endian, and the most important bytes are saved and transmitted first.
Advantages and Disadvantages
3GP is a video encoding format mainly developed to match the high transmission speed of 3G mobile communication networks. It is also a commonly used video file format in mobile phones. . 3GP is the standard format for 3G mobile devices. It is used in portable devices such as mobile phones and MP4 players. Its advantages are small file size, high mobility, and suitable for mobile devices. The disadvantages are poor compatibility on PC, few supporting software, low resolution and low frame rate.
3GP stores video streams in MPEG-4 or H.263 format and audio streams in AMR-NB or AAC-LC format. 3GP also defines the size of the video and the required bandwidth, so the video content can be correctly scaled to the resolution supported by the phone screen display.
3GP enables users to send large amounts of data to mobile communication networks, thereby transmitting large files such as audio, video and data to mobile phones. Most smartphones support 3GP technology, allowing users to record and play videos using their phones. The videos can also be saved on a PC and the converted files can be played with appropriate formats and players. These features allow users to create and record personal videos, view and modify their videos.
