I am not an expert in this field but know a little about film restoration which is the service you most likely need. The other option is to use a service that scans each frame and then links the individual scans to create the movie. Either option can be expensive but the full restoration services will yield the best results. Here are a few links to UK firms that specialize in restoration and digital transfer.
