I started trying to decipher encryption 4. There's not a lot of help out there but they tell you its based on a number system, personally it kind of looks binary. But I'm stuck so I have no idea. I read an article that hinted to search for space characters so I tried to divide the lines in different sectors.
So I divided in 2 ways, first one I divided in what I think is 1 character. Then I got a total of 11 different characters which fits in to our number system we got today but with a space character, '0-9 '. I also tried to divide the sentence with 2 characters, then I got more what looks like words but no type of number system. With a total of 12 characters, but 5 never repeating so I'm a bit skeptical to this division.
I counted up all these random characters and did a frequency analysis.
I now tried to divide the message with the most frequent character as a space to see what I got.
I got this for the single char: * spoiler *
and this for the double chars: * spoiler *
Now this is where I'm stuck, am I on the right track? Could someone give me a hint please?

I also solved this by using frequency analysis and guessing the 12 characters.
Still, knowing the answer, I cannot unriddle the ups and downs...
Why do I not see the pattern here? It should be possible to decode 4 bits at a time, right? I see the difference between 0000 and 0010. But this pattern does not comply with the other combinations...

it is basically in binary. the only thing you need to decode is how to decipher the image itself by looking at black and white.
I know the hint says up or down.. think about it.. up is on. down is off.. there you go..
I know the image may look tricky but the binary string is actually longer than the image itself. so think real carefully on how the lines go along the screen. down,up,down,up,down,up,up,up...down,up,up,down,down,up,down,up ... so on.. this is my only hint to get you going
