Can someone answer this for me? what is md5 rehashing

What is md5 rehashing and what does it mean for a youtube video?

 

[HoNeYBiRD]

Each file has a unique MD5 checksum. If a site uses this parameter to identify files, 1:1 copies can be identified easily.
Even just a tiny bit of modification changes the MD5 checksum.
MD5 hashing = changing the MD5 of a file. This can be done using different methods, e.g. adding a frame, removing a frame changes the MD5.

so, in essence, this makes a youtube video seem fresh and unique to youtube?

It is a way that youtube can check that you uploaded videos that are legitimately your own content, and not just downloaded from another youtube channel and re-uploaded. MD5 is like a finger print every file has a unique one.

YT is much more smarter than relying on MD5, many people have tried different things before, nothing has worked...
crop the video, rotate a bit, add text on it, delete some frames, change the length...you name it...nothing works...

Yes you can add a logo somewhere on the screen and youtube wouldn't recognize it as a duplicate. I got past the google reverse image search so yourube shouldn't be that hard

In itself no. Videos can be identified by different things, e.g. audio, just to mention a trivia.
How to make the videos unique? I guess you can find pointers to that in this very section.

Works fine for me.

I literally use the same video template every single time, I just change the text and make them about 5-10 seconds different in length.

Right, they probably look at a variety of factors. MD5 is just one of them. I'm pretty sure they have their own in house algos to sort through videos.

data has meta-data/footprints.
md5 is just one of the footprints.
good to spoof but like mentioned before,
big services are checking for multiple footprints.
best to spoof them all. take some time to research the topic, there's much to know.
in context of youtube, most common tactic i've seen to get past their algos is vertical flip the video...adjust the pitch...change the resolution/add border...add long intro/outro. i'm sure there's much more.
ps, favorite tool i found to do bulk md5 editing is this one.

changing the MD5 is playing a big part if you try to ripoff videos from other users

Uploaders are just better off uploading legitimate unique content that they actualy own.
