HEVC or h.265 is the most advanced codec for now because it has the lowest bitrate without losing the image quality. The codec has three main features that distinguishes it from others: parallel decoding, random access to images within the video stream and larger maximum block size. HEVC is aimed to offer the same level of video quality as AVC (h.264), but with improved compression, that is why a video file compressed with the codec will be twice smaller.

3GP is a multimedia container developed by Third Generation Partnership Project in 1998 for GSM-based (Global System for Mobile Communications) phones. The container requires little bandwidth, storage space and data usage that is why it is ideal for cell phones. It is a standard container for the files sent using MMS (Multimedia Messaging Service).
