What are MP4 videos?
MPEG-4 is a collection of methods defining compression of audio and visual (AV) digital data. Uses of MPEG-4 include compression of AV data for web (streaming media) and CD distribution, voice (telephone, videophone) and broadcast television applications.
MPEG-4 extends the earlier MPEG-1 and MPEG-2 algorithms with synthesis of speech and video, fractal compression, computer visualisation and artificial intelligence-based image processing techniques. MPEG-4 absorbs many of the features of MPEG-1 and MPEG-2 and other related standards, adding new features such as (extended) VRML support for 3D rendering, object-oriented composite files (including audio, video and VRML objects), support for externally-specified Digital Rights Management and various types of interactivity. AAC (Advanced Audio Codec) was standardized as an adjunct to MPEG-2 (as Part 7) before MPEG-4 was issued.
MPEG-4 is still a developing standard and is divided into a number of parts. Companies promoting MPEG-4 compatibility do not always clearly state which "part" level compatibility they are referring to. The key parts to be aware of are MPEG-4 part 2 (including Advanced Simple Profile, used by codecs such as DivX, Xvid, Nero Digital and 3ivx and by Quicktime 6) and MPEG-4 part 10 (MPEG-4 AVC/H.264 or Advanced Video Coding, used by the x264 codec, by Nero Digital AVC, by Quicktime 7, and by next-gen DVD formats like HD DVD and Blu-ray Disc).
How to convert MKV to MP4 on Mac OS X?

Step 4, Change MP4 Video and audio Settings
Click on the “Setting” button to expand Setting” panel.
You can change the Resolution, Encoder, Bit rate and Frame rate of the MP4 video and Sample Rate, Channels, Encoder and Bit Rate of the MP4 Audio. The size of the MP4 file depends a lot on these settings.
The bitrate is in the unit of kbit/second. Use this formula to calculate the video size per minute:
Video size/minute (KByte/second) = bitrate / 8 * 60.
Step 5, Select output directory
Expand the "Output" panel. Use the "Browse" button to select an output directory.
Step 6, Click “Convert” to convert MKV to MP4 on Mac.
