MP4 VS Other Formats - Differences between MP4 and MKV AVI AVCHD

Today's digital technologies give you a bewildering array of video formats to capture, create, edit and distribute films besides MP4 format - MKV, MOV, M4V, AVCHD, FLV and many more. Different formats mean different sizes of space they take, different video quality and compress ratio, and different screens they can play on.

AVCHD vs MP4

While based on MPEG-4 AVC/H.264 codec, AVCHD is saved in a .m2ts and mp4 file in .mp4. AVCHD uses Dolby® Digital AC-3, while MP4 adopts MPEG-4 AAC LC audio codec. AVCHD is designed by Sony for their camcorders and is suitable for Blu-ray discs and HDTV. Compared with MP4, AVCHD has better quality and large size.

MKV vs MP4

MKV is the preferred format for HD videos and Blu-ray discs as it supports H.264/AVC, a codec used for efficient HD media playback. It's in larger size than MP4 format. One big difference in MKV and MP4 is most H.265/HEVC files are stored in .mkv, which reduces file size by 50-70% with equivalent quality to MP4 H.264.

AVI vs MP4

AVI is an uncompressed format. MP4 is a lossy format using MPEG4 AVC/H.264 codec, and the H.264 codec will give acceptable quality and lower bit-rates. AVI always has better quality and larger size than MP4 format. AVI is best for storing/editing videos, and MP4 is used for web distributing and physical media.

MP4 vs M4V

MP4 and M4V are quite similar. MP4 container holds either MPEG-4 or H.264 with AAC audio, while M4V is also based on H.264 but contains DRM, AC-3 Dolby Digital audio. Besides, M4V is usually protected by Apple's FairPlay DRM protection, and is the specific format for iTunes.

MP4 vs MOV

MP4 and MOV are both lossy video formats. MP4 is based on MOV format, both can use MPEG-4. Normally mp4 has higher compression ratio thus MOV comes with better quality and larger size. MOV works under Mac environment and Apple devices, while MP4 video format is more widely accepted.

MP4 vs MP3

The biggest difference in MP3 and MP4 is that MP3 codec is used to encode audio only while MP4 contains video, audio, images and text. MP3 uses a lossy compression that can reduce audio file size without significant quality loss, thus remaining smaller size than an equivalent MP4 file.

MP4 vs other Formats:

Main differences between MP4 and other formats in short: 3GP is designed for 3G network mobile phones and optimized to reduce the storage and bandwidth requirements; WMV has smaller file size but inferior quality compared with MP4; FLV is a container format popular for video streaming online, but it doesn't contain as many files as MP4 does, and thus it has smaller file size; MPEG-4 is a compression method of audio and visual digital data while mp4 is a container format.
