    How do the People that make capture cards make them work like that?
    Also Why hasn't Nintendo caught onto this kind of thing and just simply implemented it into there own Consoles???

    It'd be pretty cool if Nintendo mass produced their official capture cards and sold them instead of having to rely on third parties.
    Bonus points if it was plug and play without requiring and kind of tinkering with the system.

    Because it costs more and most people will not use it?

    Others have already gone but I will go anyway.

    Three main options

    1) A glorified camera attached to the devices in question (probably with a shroud). They actually do this sometimes and if you watch a few video reviews from various places that show the reviewer you might see one.
    2) Decode the analogue signal as it goes to the screen and adapt it however you will. It is how http://home.comcast.net/~olimar/DS/jumbotron/ and the ones that stem from it work.
    3) Decode the signal from the actual vram itself and reconstruct it. Going by a few interviews this is what many of the old game magazines used to do to get screenshots and/or remove things to generate maps for areas in the game. This is a bit of a pig to do in real time/proper video capture rates however.

    A kind of hybrid of 2 and 3 exists for some of the older home consoles. If they were locked to only output RF or something equally nasty then looking deeper into the console may get you something nicer you can use on a more modern TV with a bit of fiddling. http://www.gamesx.com/rgbadd/rgbn64.htm is probably one of the more notable examples of this though the original xbox had a VGA mod and even older consoles have similar things.

    Later down the line you might also get things like emulators (Nintendo supposedly sent a few to various reviewers at one point) and the handhelds had long had console adapters (the super game boy, various things on the N64 and the gb player on the gamecube) which allowed you to use far more established capture methods.

    Why. Because Nintendo devices, much like all devices that are not industrial/field specific, are built to minimise costs and that would add extra.

    You have insufficient posts to view location.
    It would give nintendo the power to dictate terms on what you could do with the videos via the TOS and EULA. Given how they view play along videos on youtube and things like eSport events of their multiplayer games, you would likely not want to even use the capturecard from nintendo just from the possible TOS you would have to abide by to use it. You might be only allowed to use a limited video service that they provide with service fees, where you might not even be able to have commentary audio along with the video like you can find in LP videos on youtube.

    Other possible scenarios if your an LP uploader, that they slap an IP claim on your video and you challenge it. They would tell youtube that you likely violated the TOS or EULA and have your account shut down in the process while you try and "resolve" this issue.

    Can't have a Terms of Service for hardware.

    But yeah if they made the thing only use their specific upload service (and not store the video on the SD or anything in a usable form in the meantime) that'd be an issue... but Nintendo's not nearly that controlling.

    Sure, they would have the option of dictating what we can do with the videos. But why does that matter?
    We don't even know if they would put that kind of restrictions on it yet.
    And I'm pretty sure that, official capture card or not, Nintendo can still claim copyright on videos uploaded to YouTube.

    Not changing my point of view, it would be cool if Nintendo had a plug-and-play capture card that was produced for retail.
    Restrictions on it are a whole different matter that I didn't mention. Better wait until we know if these types of restrictions would be in place before raising an objection IMO.

    You get a catch card, and when you come into contact with a Spiny or a Dark Koopatrol, you use it. It's better if you get the red catch card because these creatures are a little harder to catch with just a regular blue card.
