    So I just got my Razer Ripsaw from the CES sale and I am really excited to use it! I have 2 issues so far that prevent me from using it.
    1. OBS keeps saying "Signal out of range" and I have contacted support about this, but have yet to hear back. It's only been a day, but I'm getting antsy because I want to use it!!!
    2. I want to do some Gamecube gameplay, but the Ripsaw only has connections for component AV cables and the Gamecube only uses composite AV cables...

    I know you can plug the yellow composite into the green component, but I get a black and white picture. No one is gonna wanna watch videos of black and white games that are supposed to have color...
    Anyone have any ideas of how I can work around this and still capture Gamecube gameplay?

    The Ripsaw has HDMI, you should be able to use a Composite to HDMI conversion box like this one, pretty cheap, only about $16 on Amazon.

    Edit: Here is a post that discusses the signal out of range problem and a solution for OBS.

    Thanks so much! I didn't realize that was a thing. Apparently there's no composite to component because "the yellow doesn't work that way" (stated by the guy I called at a store that shall not be named) but it CAN be converted to HDMI? Makes total sense...

    Unfortunately, I can't buy online, but I'm having my mom check at work and see if and how much.
    As for that post, it doesn't help with mine. I've adjusted resolution in a multitude of ways and nothing is working.

    Yeah, so what happens with composite signals is that all of the color information AND the luminance information is sent along a single cable.

    Component cables send the color information along two cables, the red and blue ones, and lighting information and sync on the green (that's why you'll hear the term 'sync on green' when converting VGA to Component. The color info on the blue cable is actually the DIFFERENCE between the blue info and the luminance, and the same thing for the red cable; the green color information is then derived from the leftover color information. The green cable carries no color information on its own, that's why when you plug your yellow cable into the green RCA port, you only get black and white. The green isn't looking for anything other than light values.

    TLDR - forget about what's going on and why you only get black and white -

    I know that there are Gamecube cables that are Component (only available for you if your Gamecube has a digital output), but a quick look on ebay has them looking really expensive! There are adaptors to go from Composite to Component on ebay, but the ones you would need look to be around $80 US. The price is because it's not just changing from one type of cable to another: there is some signal processing going on there.

    That box that @bmoconno links to looks alright, but I wouldn't trust the Full HD 1080 symbol. It might have a 1080 output, but the original signal is only 480i (or 576i, depending on your region), and won't look fantastic.

    This is very important to keep in mind. The GameCube wasn't an HD system, especially not when outputting through the Composite cables, so if you're recoding with the plan to upload it or stream it, you're going to need to probably add a significant border to the finished file or broadcast at a much lower resolution.

    Thanks for the information guys! I don't mind too much about resolution, I can figure that part out later on. The tough part right now is getting the Ripsaw to see the image and getting full color. Honestly, I bought the Ripsaw because I thought I'd be able to do this without too much difficulty. Didn't know I was gonna have to spend the same amount as the Ripsaw in stinking cables to get everything to work right... I can't afford $80+ in cables/converters and stuff.

    Oh, I forgot to mention too that Gamecaster can actually record the image. It's black and white, but it can see it. I can't use Gamecaster though because it lags out my system so horribly. Like, the mouse lags moving across the screen just having the preview window open... OBS just says "Signal out of range" and nothing I've done fixes it.

    Okay... So I just tried to see how much shipping would cost and that converter can't even be shipped to my address -.- I literally have never used Amazon before, JUST made an account to see price and it was all for nothing... wow.

    Yeah, it'll always be black and white unless you're using something like that converter box.

    The Component cables carry the video image differently than composite cables do. In composite all the video information comes along the yellow cable, but in component the video is split between three different cables.

    The Green cables carries what is called the "Luminance" (or intensity) and synchronization of colors.

    Edit: To explain, you get the black and white image from the green cable because it's showing you the intensity from black to white of the image.

    The Red cable carries the difference between the color red and the Luminance signal carried on the Green cable.

    The Blue cable carries the difference between the color blue and the Luminance signal carried on the Green cable.

    The device the cables are plugged into (like the converter box) interpolates the Luminance and the colors Red and Blue to produce a full color video stream.

    That's weird. Are you in the US? I've never heard of Amazon not being able to ship somewhere.

    I see now that you're in Canada, you'll need to reference this link instead.

    Hahaha! I said ALL of this in my post! Maybe I shouldn't have put that "TLDR" part in there. ;)

    Alright, well thank you again. I will keep this link here while I wait for Razer support to get back to me and then we'll see what happens.

    I know, I was re-iterating in a smaller block of text to make it more readable. A slightly longer tl;dr than your one. :stuck_out_tongue_winking_eye:

    Okay, so to update on this I did figure out how to get OBS to see the Gamecube input. I had to adjust the resolution down to 480p, which kinda sucks, but, it's not like you'd get high quality graphics from the Gamecube anyway, so it's fine. It works. That's the important thing!
    Next problem is I still have to get a converter for actual color :/
    Either that or Razer should just add support to the Ripsaw for composite cables... That would be nice.
    For the Xbox 360, I had to adjust resolution down to 720p. I didn't try that before because every guide/info I looked up said 1080p. I stream at 720p, so maybe that's why it worked.

    That probably won't happen, Composite is analog and a pretty dead technology. It's for the benefit of everyone to just let is die off.

    Glad you got OBS working though!

    Maybe, but some people seem to really like old gameplay because of the nostalgia and that. Heck, I could even play games, and stream them, on my Grandma's old NES! That would be really cool!
