An MP4, also known as an MPEG-4 video file, is a compressed file that contains not only video but audio and subtitles. One of the more popular video formats for both desktop and mobile devices, MP4 files have a high degree of compression, which reduces quality loss and produces smaller file sizes. This makes the MP4 format ideal for streaming video and other larger media files.
Whether you want to make a slideshow featuring footage you captured on different cameras or a highlight reel composed of your favorite sports clips, Adobe Premiere Pro makes it quick and simple for any video editor to combine MP4 files.
