Transfer videos from Sony HC9 tapes to Windows 10 laptop
iLink will give you a lossless digital transfer of the source material, if maintaining perfect quality is important, I would go with that connection. DON'T attempt an iLink/1394 to USB adaptor, if you do some research, those adaptors just don't work. You'd need to buy an interface card for your laptop to go this way, depending on whether your laptop has an ExpressCard or PCMCIA slot, there are interface cards available.

Otherwise search "HDMI to USB" on google, there are plenty of devices to connect that way as well. Downloading the video this way will re-encode it on the laptop side, so it might degrade the quality a little (although in most cases not noticeably), and might be a little more CPU intensive on the laptop, so just be aware of that.
