yeah, that's Apple's DV codec. they'll look fine if exported to tape, but not if they stay digital. I capture mostly animated content that is unusally bright, but I think I have got it almost back to normal anyway with Media Cleaner by doing a 25% gamma increase, 10% contrast, and 10% black restore. I also use the Mild noise reduction setting and adaptive deinterlacing. I don't know how much of this you can do outside Media Cleaner, but I bet MediaPipe can do it all, just more complicated interface
