Stereo Madness, but space and time are swapped (READ DESCRIPTION) — Geometry Dash

Stereo Madness, but space and time are swapped.
Questions and answers about this video.
Q: What does mean "space and time are swapped"?
A: Space and time refers to the horizontal axis (X-axis) and the time axis (T-axis).
Q: How does it work?
A: Imagine the entire video as a box, where each layer is one frame. And we "cut" this cube into frames from the other side, not along the T-axis, but along the X-axis.
Q: Why is the player only visible at 0:21-0:26?
A: Visually, the player stands at one place along the X-axis. And since the X- and T-axes are swapped, now the player is visible only at one time.
Q: Why is the video shorter than the level itself?
A: In order for the video resolution to remain the same after conversion, the number of frames in it must be equal to the frame width. For 4K resolution, this is 3840 pixels, which means that the original video needs to have 3840 frames. Accordingly, I had to record the level not on usual 60 fps, but on ~ 44.8 fps, so that the recorded video had the required number of frames. And for the converted video, fps was increased to 60, while the number of frames remained the same. Therefore, the length of the video has decreased (to 3840/60 = 64 seconds).
Q: What happened to the music?
Q: How long did it take to create this video?
A: It took my computer a total of almost 15 hours to convert the video (and ~95 GB of free disk space). But I wrote the code for this in less than an hour. I've already optimized the code, next time should work faster.

Also I can record any your level in high quality. Write to me in Discord (LeTim#2685).

this feels like what might happen if you randomly delete one of the game files

This definitely goes to my mythical playlist

If you are confused, imagine the YT time-bar is the position on the screen. Not the position in the level, but the whole level, at one spot on the screen. So the start is the left side of every frame, left of the cube, which is why it's not visible. The player is only visible at around 0:23 because the cube stays at the same spot on the screen.

This is what happens when you play stereo madness near a black hole

I’m still trying to wrap my head around what’s happening lmao

[Ceereeal]

okay I think I understand what’s going on. each vertical column of pixels is a position in a time interval of the level. Each time interval is the level divided into 3840 equal parts, because of the 3840 horizontal pixels on 4k resolution. As the video plays, the vertical slice of pixels being displayed slowly shifts from showing the left side of each time position to the right side.

TLDR, the video is showing each “frame” of stereo madness as a slice of pixels and is slowly moving left to right for each frame, showing different slices for the same “frame”

Okay sure, some of us may understand how it works, but I assure you none of us knows how the heck you did it.

Офигенное описание чувак, пришлось вернуться в школу и посидеть там пру уроков, чтобы понять, как это работает :)

[spicytakis]

Oh I thought it was only. Cuz it's just like the stereo madness I play.

Stereo madness but it's actually madness

[DV_zzz]

все пишут про видео, а я напишу, что благодаря описанию научился конвертировать музыку в png, спасибо letim!

[nishionary]

this is most weirdest "level name, BUT..." vid :0

[Mewtwo]

It'd be funny to see this shown to Robtop and get confused on whether the game broke again somehow or his brain did.

Это очень интересная задумка, делай больше видео с такими интересными идеями, а это видео, пожалуйста, оставь в количестве одной штуки, одного видео с такой тематикой вполне достаточно!

напоминает рассказ про улицу Герцена и мурманский полуостров.

Alternative title: Stereo Madness, but on my Nokia

you record a level at, let's say 4K resolution (3840 horizontal pixels) and the fps needed to make sure there are exactly 3840 frames
you split the recording by every frame, and slice those frames so they're 3840 times thinner than the video's width
now you wanna make sure the part of the original picture that the slice is showing moves from the left side of the picture to the right, so the slice can show the entirety of the given frame
repeat for all 3840 frames and stack the slices together to make them the same width as the original video (3840 pixels)
here, the time the slice takes to show the full frames obviously depends on the song, of which the process is explained in the description
this is also why the player only appears at a specific part of the video, the x position of the player relative to the screen stays the same practically the whole time in stereo madness

why does the level fade in at the start?

Как к тебе вообще пришла такая идея? Будь у меня бесконечная жизнь, я бы никогда до такого не додумался.
