Differences between video file formats and codecs<\/p>\n
In this article, I will explain the difference between “file format” and video “codec” in an easy to understand way.<\/p>\n
First of all, I don’t understand the meaning of “file format” and “codec”<\/p>\n
Even such people can understand it without much thought.<\/p>\n
To conclude first<\/p>\n
File format (.mov \/ .mp4, etc.) \u2192 Video container
\nCodec (H264 \/ AIC, etc.) \u2192 Video compression method
\nIt makes a big difference.<\/p>\n
To summarize briefly, the codec is the method of compressing the file format.<\/p>\n
There are many video file formats and codecs.<\/p>\n
Even if the file format is the same, if the codec used is different, it may not be playable depending on the environment. Therefore, knowing these differences and types will be helpful when making or playing videos.<\/p>\n

\nUnderstand the file structure of videos
\nFirst, let’s take a quick look at the structure of video files!<\/p>\n
The file format of the video can be recognized by the “extension” when the video is placed on the desktop.<\/p>\n

\nBy the way, this is a video file in “.mov” format.<\/p>\n
There are several types of file formats (video containers), but the content is the same.<\/p>\n

\nfile format There are various formats such as “.mov”, “.mp4”, “.wmv” and “.avi” in terms of extension. Some file formats cannot be played depending on the type of terminal or PC.
\nVideo data The visual part of the video file. Without this, the image will not be displayed on the screen. Due to the large volume of video data, it is almost always compressed.
\nAudio data Sound data. Without this, there will be no sound. Although the capacity is small compared to video data, it is often compressed as well.
\nMetadata Text data such as copyright information and shooting date and time.
\nFeaturing three main file formats<\/p>\n
I mentioned earlier that there are several types of “file formats” for videos.<\/p>\n
If you know everything, you will lose motivation, which is why I will introduce three main video file formats.<\/p>\n
Quick time (.mov)
\nIt is a video file format created by Apple Inc. called Quick Time Movie.<\/p>\n
You can play it with QuickTime Player on Mac or iTunes.<\/p>\n
To play on Windows, you need to install the Windows version of QuickTime Player (free).<\/p>\n
Orally, it is called a “mob file” or “M point or buoy”.<\/p>\n
Windows Media Video (.wmv)
\nThis is a video file created in Microsoft’s “Windows Media” format.<\/p>\n
It can be played with Windows Media Player on Windows.<\/p>\n
If you want to play it on Mac, you need to download a media player like LVC.<\/p>\n
Taken by mouth, it is called “Double MV”.<\/p>\n
MP4 (.mp4)
\nYou have probably heard more about video files.<\/p>\n
The reading is “MP4”.<\/p>\n
This is the most widely used format.<\/p>\n
You can play it with QuickTime Player on Mac, iTunes, and Windows Media Player on Windows.<\/p>\n
It is also compatible with many mobile terminals.<\/p>\n","protected":false},"excerpt":{"rendered":"
