I have a consolised NeoGeo MVS and the output is scart I have tried using a scart to AV adaptor to capture and record but wont work? help???

Sorry I didn't see this sooner. If trying to capture footage id recommend pairing a OSSC with a hdmi capture card. That combo can be a bit pricey, an OSSC from Kaico is sold here: https://amzn.to/2Izd3Z9 A cheap HDMI capture card can be found here: https://amzn.to/3kcO5g2
