What is WMV-HD video format
High-definition video has been widely used in various fields. Among them, video processing and encoding are very important in streaming video, especially video format, which has become the main indicator for subsequent transmission and playback. There are many video formats at present. The following is the WMV-HD format.
What kind of format is WMV-HD? How is it different from WMV? WMV-HD is a video compression format created by Microsoft, a giant in the software industry, and generally uses .wmv as the file suffix. Its compression rate is even higher than the MPEG-2 standard. If MPEG-2 is used, the same 2-hour HDTV program can only be compressed to 30GB at most. If a high-compression encoder such as WMV-HD is used, it can be compressed to less than 15GB without any reduction in image quality.
The original audio and video data need to be compressed and encoded. Similarly, WMV-HD is a compressed format based on the WMV9 standard. It is the latest version of the video compression technology series developed by Microsoft. Although WMV-HD is Microsoft's unique standard, it has been rapidly popularized in desktop systems because it strongly supports the WMV series version in the operating system.
In terms of performance, the data compression rate of WMV-HD is the same as that of H.264, and the application fields of the two are also extremely similar. Therefore, in the competition for the dominance of the new generation of mainstream video encoding standards, the two sides have launched a tit-for-tat struggle, and the focus of the struggle is on the next generation of optical disc specifications "HD DVD" and digital microwave radio and television. HDTV files that generally use .wmv as the suffix are compressed by WMV-HD.
There are many streaming video formats, and the final choice of compression format is mainly based on application requirements and transmission bandwidth. Meifit is a company specializing in the research and development and production of video capture cards. It has been focusing on the research and development and development of technology for many years. The video capture cards currently launched have been widely used in various industries. For example, the mainstream streaming capture cards all use soft compression mode, which can be directly compatible with common streaming software and realize direct application and other operations.
