Capture it interlaced, preferrably as losslessly as possible, then use deinterlacing software where you can fine-tune the settings if you need to.
And keep the original interlaced versions too! You never know in the future you may want to use a newer deinterlater that works better. Or a new codec that can preserve more details in smaller files.
I’d keep the tapes too, you never know when the community will come up with better VCRs like how it’s happening in the retro computer world where we have things like the GreaseMonkey that can store the raw magnetic transitions on the platters and floppies.
