Video formats include AVI, MPEG, MP4, WMV, FLV, MOV, MKV, RMVB, 3GP, etc. Detailed introduction: 1. AVI is a common video format developed by Microsoft. It supports multiple codecs and audio formats and has wide compatibility. Due to its larger file size and lower compression rate, The AVI format is gradually being replaced by other more efficient formats; 2. MPEG is a collection of video and audio compression standards, MPEG-1 and MPEG-2 are the two most common formats, etc.

avchd is a high-definition video camera format jointly launched by Panasonic Industrial Co., Ltd. and Sony Corporation. The format combines the existing DVD architecture (i.e. 8cm DVD disc and red light) with an advanced compression based on MPEG-4AVC/H.264 technology codecs integrated together.

m4v is a video format used on online video on demand websites and mobile handheld devices. It was created by Apple and used by iPod, iPhone and PlayStation Portable. m4v is a special type of MP4 format, based on the second version of MPEG-4 encoding. Its video encoding uses H264 or H264/AVC, and its audio encoding uses AAC; it uses H264 high-definition encoding, compared with traditional On2 VP6, H263, Divx, etc. , able to achieve higher clarity with a smaller size.

m4v can directly change the suffix to mp4, but this method can only be used when the encoding is the same; if used on videos of different encodings, the file may not be opened. In different encodings, if you want to ensure that there will be no file corruption problems after video conversion, you need to use third-party video conversion software to convert M4V to MP4 format.

The video format that takes up the smallest space is AV1. AV1 uses advanced compression technology to significantly reduce video file size while maintaining high video quality. Compared with other common video formats, AV1 has higher compression efficiency and smaller file size. AV1 uses a variety of technologies when compressing video. Intra-frame prediction and inter-frame prediction can effectively utilize the spatial and temporal correlation in the video and reduce the storage of redundant information. Transform coding and entropy coding can further compress video data, reduce file size, etc.

Adobe PremierePro can handle various video formats, including MP4, AVI, ProRes, DNxHD, etc. 1) It supports a variety of codecs, making it easy to import and output videos. 2) Use the SDK to programmatically control the import and output process. 3) Media browser helps preview and select formats. 4) Proxy files can optimize high-resolution video processing. 5) Keeping files organized and regularly backed up are best practices for handling different formats.

m4v is a video format used on online video-on-demand websites and mobile handheld devices. It is a special type of MP4 format. Its suffix is ??often ".MP4" or ".M4V". Its video encoding uses H264, and its audio encoding uses AAC.

The most common general video formats include MP4, WebM and Ogg, among which 1. MP4 can be played on almost all devices and platforms, especially natively supported by mobile phone systems (such as iOS and Android), suitable for shooting, downloading and editing; 2. WebM and Ogg are recommended for web pages, both of which are open source formats and are suitable for online playback. WebM performs well in Chrome, while Ogg is suitable for Firefox and Safari; 3. Although some platforms such as Douyin and YouTube support multiple formats, it is recommended to upload MP4 to ensure compatibility and pay attention to encoding parameters and resolution limitations.
