High-definition video has been widely used in various fields. Among them, the encoding and processing of video in streaming video is very important, especially the video format, which has become the main indicator for transmission and playback afterwards. There are many video formats at present, we will introduce the WMV-HD format below.
What format is WMV-HD, and how is it different from WMV? WMV-HD is a video compression format created by software giant Microsoft Corporation. It generally uses .wmv as the file extension. Its compression rate is even higher than the MPEG-2 standard. It is also a 2-hour HDTV program. If MPEG-2 is used, it can only compress up to 30GB. Using a high compression rate encoder such as WMV-HD will not degrade the image quality. Under the premise can be compressed below 15GB.
The original audio and video data needs 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 unique to Microsoft Standard, but because of its strong support for WMV series versions in the operating system, it has quickly become popular on desktop systems. 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 very similar. Therefore, in the struggle for the dominance of the new generation of mainstream video coding standards, the two sides launched a tit-for-tat struggle, and the struggle The focus is on areas such as the next-generation optical disc specification "HD DVD" and digital microwave broadcasting. HDTV files that use .wmv as the suffix are WMV-HD compression.
There are many streaming video formats. In the end, what format is selected for compression is mainly selected based on application requirements and transmission bandwidth. Mayfit is a company specializing in the development and production of video capture cards. It has been focusing on technology research and development for many years. The current video capture cards have been widely used in various industries, such as mainstream streaming media capture cards. All are in soft compression mode, which can be directly compatible with common streaming media software to achieve direct application and other operations.
