Compare 3GPP Video and Matroska Video formats — understand the key differences and when to use each

Format Overview

3GP

3GPP Video

3GPP Video (.3gp) is a video file format.

.3gpvideo

MKV

Matroska Video

MKV (Matroska Video) is an open-source, flexible video container format created in 2002. MKV can hold virtually unlimited video, audio, subtitle, and attachment tracks in a single file, making it the most versatile video container available. It supports every major video codec (H.264, H.265, VP9, AV1), audio codec (AAC, FLAC, DTS, TrueHD, Atmos), and subtitle format (SRT, ASS, PGS). MKV is the preferred format for high-quality video collections, Blu-ray rips, and anime with multiple audio and subtitle tracks. It supports chapters, menus, metadata, and attached fonts. While MKV has excellent software support (VLC, MPV, Plex), some hardware devices and smart TVs have limited MKV compatibility. For maximum compatibility, converting MKV to MP4 is recommended.
