A mac laptop can happily cope with compression and decompression of Apple ProRes 422 / HQ at standard definition resolutions but you need a quad core or better for handling it at HD resolutions. Veescope, FCP or otherwise (and all will work OK for capture) if you're specifically need to capture 1920x1080 baseband as Apple ProRes 422 then the MXO2 is not the right choice.
