I too applaud DVDranger for attempting to make a product to defeat cinavia.
(not that I am likely to buy the product though)
Over the past couple of weeks, I have performed many tests to see how the cinavia works and in the process of refining as I go.
I believe I have discovered interesting things, right now, I am roughly documenting them.
I have much work to do yet however…so don’t anyone get their hopes in a perfect solution, in fact, as it stands now…unless someone has the design build of the watermark, I have serious doubts there will ever be a method that can defeat it without mangling the audio to a certain extent.
I now know enough about it to realize that the results of defeating it with filters will have some smear/ tonal changes.
So my conclusion as it stands right now is the best we can hope for is a result that won’t trigger the cinavia detection but the process will have audio degradation.
Really though think about it, they said it couldn’t be broken, that is already proved untrue as DVDranger has a version, Macrovision3500 has found at least 2 methods and I have a couple of models as well…not that mine are any better…perhaps worse…there likely would be difference of opinions about them.
Right now though, I am ready not to relate mine…I have seen how the others have been torn up and down…and I would like to better mine before I make them public.
Could be some time yet…as I am not in any hurry and still in the phase of first detection (at the 20 minute, 20 second)…if it is border line then the detection kicks in @ 21~20 second…and I have one result to kick in @ 23 minutes.
Also, I am only working with stereo/2 channels as I see no need to include multi-channel with the rough results obtained.
Believe me, it is not easy to keep the detection from not happening in the first place–with an audio that can be listen-able and there are a lot of filters that simply don’t work…even though they mangle/smear.
So let’s keep an open mind…even though the alternatives of workarounds of not playing from a physical disc/non-cinavia detection hardware/software are no doubt the best way to go.
I took this on not that I really need to but as a challenge to see what I can find out about the subject(some people enjoy working crossword puzzles)…the more we know about it…can’t hurt to know more.
I have a lot of ideas to try out to see if I can improve the audio output and/or document how it behaves to various scenarios.
