F4V is a well-known flash video format developed by Adobe System. It is supported by Adobe Flash Player. Currently, approximately 80% of online videos are transmitted using Adobe Flash technology. Files with the F4V extension are called a container format. The F4V format, in comparison with other files of the FLV category, uses boxes to store information. In addition to devices with an operating system from Apple, these files can play almost all browsers that support flash video playback. F4V files resemble .FLV files, but use “blocks” to store data. Examples of blocks that are supported by the F4V format include meta block (metadata), moov block (file header), ftyp block (requested player tools), uda block (user data in free form), etc. The format container, in the development of which the ISO Media File Format was used, initially used the Quick Time Container Format from Apple. Compared to the old FLV format, the F4V format is fully compatible with the h.264 and ACC formats. This provides an opportunity to use other container formats.
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.
