In terms of software compatibility, codec quality and system stability, it is also a sign to test whether a high-definition acquisition card is good or not. In addition, there are third-party software and development tools that support the development of standard DIRECT SHOW API. Do you provide SDK secondary development packages that are compatible with many common non-editing software, such as Adobe Premiere pro? Many acquisition card manufacturers, such as Yuan Gang and other established acquisition card manufacturers, have produced high-definition acquisition cards with high cost performance, which greatly lowered the threshold for full-resolution HD production. In the rising field of high-definition acquisition, such as educational recording and broadcasting, network video conference and remote training, high-definition medical care, stunt booth and other multimedia high-definition video acquisition cards, VGA acquisition cards are the most popular, which can not only collect computer screen signals, but also collect high-definition VGA camera signals, medical VGA equipment signals and so on. It has a wide range of applications, especially in video conferencing, webcasting, distance education and projection fusion. However, there are many image acquisition cards on the market. How to choose VGA acquisition card correctly?
1. First, before purchasing the VGA acquisition card, you should specify the requirements, such as the required resolution, soft compression mode or hard compression mode, supported software, etc. There are many models of VGA card in the market, which may be produced by different manufacturers, and each model of VGA card focuses on a specific function, so we'd better make clear the purpose of buying VGA card before buying it.
2. Secondly, the built-in video capture card is mainly divided into PCI-E and PCI slot interface. The bandwidth transmission speed of PCI-E slot is twice that of PCI, so most high-definition video capture cards use PCI-E slot interface, which requires the motherboard you use to have such a slot.
3. Finally, video resolution is very important for video applications, such as live network video and Internet video. These all have certain requirements for video resolution, and high-definition standards are very beneficial to publicity and effect. For example, the high-definition video capture card introduced by VIV Image supports the resolution of 1920x 1440, and can automatically identify and adapt at its resolution.
4. In addition, the professional VGA capture card is expensive, and its performance is outstanding compared with the general video capture card. When purchasing VGA acquisition card, we need to consider it from our own or user's point of view, which not only meets the demand but also saves the cost.
