If you're converting old home movies for putting on a DVD, even that will be overkill. While 4K and 60fps (or higher) are ideal and future-proof, if you don't need that kind of performance, you can save money by getting a capture card that focuses on 1080p, for example. Keep in mind what resolutions and frame rates they support as well. Understandably, most modern capture cards stick to HDMI, which is the most widely-used interface for transmitting audio and visual, but that means if you want to import AV from sources that don't have HDMI, you'll either need to find a capture card with more options, such as coaxial or phono inputs (which are increasingly rare and expensive), or use a converter.
When buying a capture card, you should also consider the inputs it accepts. These plug into your computer via USB, and that makes them much easier to install, and means they are also compatible with Macs and laptops. The good news is that there are a growing number of modern external capture cards.
