I do Video SEO and Youtube Marketing, and can say that their are two ways to get past this.
PM me, and I'll shoot you a way to get this done.
This is just no way to conduct yourself on the forum HorusBlack. If you have the answers the OP seeks, you can clearly see that many others in the thread are also seeking these answers. This is a board of like-minded webmasters who freely share answers in response to these types of questions.
Why not simply share your two approaches directly here? Frankly you won't be revealing a big secret since there are approximately 50-75 other threads on BHW related to this exact topic where the answers are actually located to this question already. Common approaches include using filters, changing MD5 hashtags, eliminating ALL Meta-data(sometimes, but not the best tact since youtube can use the meta data). However, sometimes directly editing any adverse meta-data can eliminate some identifying factors.
HorusBlack - I hope you will consider actually sharing your solutions rather than phishing for PMs. It kind of makes it look like you are intending to somehow sell a solution to the OP instead of just helping.
Do you really know any solutions there guy, and if so, care to share with the rest of BHW? There's no reason to solicit PMs in this nature in my opinion when it would take you about 1 minute to list the solutions. Beyond that folks, I would suggest that the answer to this question is already present on BHW, and that the search function can go a long way to getting you back on track for uploading videos to youtube.
PM me, and I'll show you how to use the search function OP. <- Sarcasm. I'm sure you all know how to use it.
To my knowledge and understanding as others have pointed out above - videospinblaster is one solution that is definitely working. If you can't pay for the software, it might help to find some information about what exactly the software does in order to achieve video uniqueness. If you can't buy the solution, maybe you can decompile a workaround based on the information pursuant to HOW videospinblaster makes all these videos unique. Overall though I'm confident it uses a mix of filters, speeding up and slowing down the audio track in different places, adding some strategic "blotlike" splatter on the video, and altering the MD5 hashtag. You may wish to either buy it since it is a working solution, or implement whatever you can learn about its overall functions.
Good luck OP!
