I don't recommend normalizing differences, as in using both sources as input to produce one "cleaned" output. It could leave watermarks that happen to be the same in both sources. I recommend having a tool that works on a single source, then verify that it produces the same output from multiple sources. Also when downloading multiple times, try to do that from different public IPs and accounts.
