so id like to record my wii with the amarec program if i use AMV4 Video Codec i can record but it has the water mark on the bottom left and because thats annoying i tried all the other video codecs and all gave me this error

I'm not sure if it's the case for Avermedia (juding by the status bar in the screenshot), but most of my video capture cards can be used in OBS Studio directly as a 'Video Capture Device' source.

Id like to use amarec to record "raw" runs without mic or other stuff

Just the game and its sound

You can do that with OBS. Just mute the Desktop and Microphone sources

but id like to do it while im streaming and i use webcam and a microphone on stream but i dont want that on my "raw video" i think ZFG does this
