user2811: I have a camera which outputs uncompressed HDMI. I understand that I can buy an external recorder (e.g., Atomos) to record the video, but is it possible to use an ordinary laptop (or desktop) computer instead?

user10931: Blackmagic Design's Decklink cards are a starting place for desktop computers: https://www.blackmagicdesign.com/products/decklink
For laptops there's both Intensity: https://www.blackmagicdesign.com/products/intensity
And UltraStudio: https://www.blackmagicdesign.com/products/ultrastudiousb3
Other companies also make such products (and even Blackmagic Design offer yet more options), but the above provides a range of answers to your question.
