Part 3: Basic Idea of Video Files

Video format can be pretty confusing, especially when it comes to its container and codec. Having a better understanding of the two technology concepts will ensure an easy video conversion on your Mac OS and a limitless video playback.

Video Formats

Container: A container format refers to a bundle of files, consisting of an audio codec and a video codec, though it may also comprise things like subtitles. Containers are usually identified by file extensions like .AVI, .MP4, .MOV, .MKV, etc and vary depending on the codecs they support as well as other features like subtitles or chapters.

Generally, the open-source MKV is extremely popular among the massive containers since it supports almost all codecs under the sun as well as other extra features. In the meantime, MP4 is considered as the most widely used format container compatible with many platforms like iPhone iPad Android. This is why many Mac users opt for converting videos to MP4 format for playback later on.

Codec: Short for coder/encoder, a codec interprets the video file and determines how to play it on your screen. It is the chief determiner of quality. The common video codecs include DivX, XviD, MPEG(MPEG-1,2,3,4), x264, etc. It is used to compress a certain standard of video respectively into a hard-drive friendly amount of space. Generally a few video's file extension usually refers to the container.

A few containers have codecs that they almost always use and other containers are often used with many different codecs. And the thing goes worse as many device only supports the video files with one specified codec. Here we give a typical example: Apple iPhone officially supports MP4 format with MP4V, H264 codecs, so if you saved MP4 file with other codecs on your Mac, problem will occur during the video playback. The only solution to solve the issue is to convert MP4 videos on Mac to iPhone supported format beforehand.

Part 4: Two Mainstream Types of Video Files

In a general way, video files can be classified into two catalogues including HD Videos and SD videos. Popular HD videos are AVCHD, MKV, MTS, M2TS, TS, MOD, etc that photographers are not unfamiliar with. Particularly, both SD and HD videos are nit-pick at media players to some degree. They need to convert unplayable videos to Mac readable format for seamless playback. Below is the table about the two types of popular videos that will do your video conversion a great favor.
