VEP is a video editing project file. It does not contain a video recording, but only indications of what video clips to take and how to “dissect” them. She developed the VEP format, i.e. Video Editor Project, Online Media Technologies. Such files are created when you work with the program AVS Video Editor. This program provides the user with the ability to make their own videos or home videos. VEP files are responsible for keeping the timestamps of such videos. They also store a variety of reference data related to the video. Such data may contain information regarding both video data and audio data. VEP files use XML formatting, but they still have a few blocks of binary data that are encoded as text for sketching video and images. The VEP files created during the production of the AVS video file are located in the Content folder on the user's computer, and it, in turn, is located near the project folder. If you need to use the program AVS Video Editor, then note that all files to be edited must have the extension VEP. Once the video editing process is complete, you can convert it to its original format. You can also leave it in VEP format.
3GA is a 3GPP audio file created in 1998. It was created by the 3rd Generation Partnership Project. It is used mainly on mobile devices in order to record, play and transmit audio data. 3GPP (3rd Generation Partnership Project) is a consortium that develops specifications for mobile telephony. The format resembles 3GP files, however, it includes only audio data. In most cases, 3GA files are used by mobile phones in order to record and transmit audio data. For example, this is how audio is recorded in Samsung Galaxy phones. The .3GA file extension can be changed to .3GP, which is widespread. Everything is supported by many programs. The 3GA format uses an adaptive coding audio codec with variable speed (AMR, AMR-NB, GSM-AMR). The development of this codec was done in order to compress encoded speech signals using adaptive modulation. In 1999, the 3GPP consortium adopted the Adaptive Variable Rate Coding (AMR) standard. Currently, it is used by GSM and UMTS communication systems. It is this format for speech recording that has found wide application on mobile devices. We note at the same time that it is not possible to play such files very often on certain devices.
