avi Audio and video interleaving. An old container that is a Windows standard. Although it is widely used, it is rarely used on video sharing sites because it is incompatible with browsers. Most of the editing programs support this AVI format, making it very easy to edit. It’s a good idea to use this as a reference when editing. In addition, there is a large amount of data that can be stored. Video part: “MPEG-1 \/ -2” “H.263” “H.264” etc.
\nAudio part: “Linear PCM” “MP3” “AAC” etc.
\nmov This is a Macintosh standard. It can be played with QuickTime, etc. It works well with browsers and can store a wider range of data than AVI. If you’re on a Mac, it’s the basic container for editing and playback. Video part: “H.263” “H.264” “Pixlet”, etc.
\nAudio part: “MP3” “AAC” “Apple Lossless”, etc.
\nwmv Official name “Windows Media Video”. It is a Windows standard. It goes well with web pages. However, since the data format that can be stored is smaller than that of avi, there are few users. Not suitable for editing. Since it supports Digital Rights Management (DRM), it is mainly used for general business and organization video distribution. Video part: “H.264”, etc.
\nAudio part: “WMA”, etc.
\nmpg Synonym for mpeg. Compared with avi, etc., the video data that can be stored is very small, only “MPEG2” and “MPEG1”. This format is often distributed as video content on the Internet. Video part: “MPEG-1 \/ -2” only
\nAudio part: “MPEG2” “AC3” “LPCM” “DTS” etc.
\nwav A container format for speech data developed by Microsoft and IBM. It is also described as “WAVE”. Reading is “wave” and “web”. It is commonly referred to as a “wave” to avoid confusion with the Web. Typically often used for uncompressed and linear PCM sampling, it can also contain compressed audio data such as “MP3” and “WMA”. Video part: None
\nAudio part: “MP3” “WMA” “LPCM” etc.
\nmp4 There is a codec with a similar name, but this is a container. It is often used for video sharing sites, such as YouTube, that claim to have “high image quality.” In many cases, the voice is distributed as a single unit and in this case it is used for the ringtones of mobile phones. Video part: “H.263” “H.264” etc.
\nAudio part: “MP3” “AC3” “AAC” etc.
\nflv It is a video container in flash format that is often used on YouTube. The main content is “H.263 \/ H.264”. It is widely used in video sharing sites because it is very compatible with web pages. The official name is “Flash Video” Video part: “H.263” “H.264” etc.
\nAudio part: “MP3” “PCM” “ADPCM” “AAC” etc.
\n3gp This is a video file recorded by 3GPP. It is used in the “i-motion” function of the “FOMA” mobile phone service provided by NTT DoCoMo. If you want to play the video on a doCoMo mobile phone, save it in this format. (Except for smartphones) Video part: “H.263” “H.264”, etc.
\nAudio part: “AAC” “AMR”, etc.
\n3g2 This is a video file recorded by 3GPP2. It is based on MP4 format. It is used in the “EZ movie” function of KDDI’s “au” mobile phone service. If you want to play the video on your au mobile phone, please save it in this format. (Except for smartphones) Video part: “H.263” “H.264”, etc.
\nAudio part: “AAC” “AMR”, etc.
\nTerm supplement
\nSome new terms have emerged which will be briefly explained here. I would like to write more details in another article.<\/p>\n
fire
\nA still image. The video is made to appear as if it is moving by displaying a series of still images at high speed. 30 frames per second means that 30 still images are displayed per second. The unit is “fps” (the frame rate is said to be 30 fps, etc.). If this value is high, the video will move smoothly. (Frames per second)<\/p>\n
Compression rate
\nIt is often used as an index of how much the file size is suppressed.<\/p>\n
Bit rate
\nThis is an expression that represents the amount of data (number of bits) that can be sent and received per second. The unit is bits per second (bps). If this value is large, it will increase the amount of data that can be sent and received per second and improve the quality of music and videos.<\/p>\n","protected":false},"excerpt":{"rendered":"
