The video capture card can be divided into two types: external video capture card and internal video capture card. Therefore, you have to make your decision about what kind of video capture card you want to use in advance. From my perspective, it is not advisable for you to use an internal video capture card.
The reason is that an internal video capture card is completely dependent on USB bandwidth, which will cause a lot of difficulties and problems for you in practice. I firmly believe that you are aware of how slow the USB bandwidth is. In daily life, you must have noticed that your USB mouse moves extremely slowly when you are using your webcam. Therefore, an internal video capture card is not a wise choice. USB dongles have the same issue.
Honestly speaking, you can never expect to capture 1080p video at 60fps by using your USB ports. It is impossible to happen. What you are likely to get is just around 5fps at 1080p 1:1. You have to fully understand this situation and then you can think about it and make wise decisions. Having taken this situation into consideration, I would surely advise you use an internal PCI or PCIe Video Capture Card. My reasons are as follows and you can judge it on your own.
A PCIe Capture Card uses the PCI-Express slot, which is the basic and essential component of any qualified motherboard. To make it easier for you to understand, the PCI-Express interface is specially designed for the better operation of high-end graphics card. As a result, the data transfer between the CPU, RAM and card is ultra-fast. It is very wise of to use the PCI-Express interface for it will bring a large amount of benefits to you! Now go and buy it for yourself!
