The new ending to DBS?

Is this new ending with kid goku his childhood or GT?

Also what is the 70cm squared window? What is it referring to? What else if anything can be take from the ending?

I'll assume it's kid goku since it shows the young characters then goes to older goku with the newer characters. But it's still interesting and what is the window reference?

It does end with an interesting scene of the shenron dragon or similar. A bit like when goku combines with the dragon. I forget if that was the end of Z or end of GT.

It's Kid Goku, he is wearing the same Gi he did at the very start of Dragonball, he even still has his staff.

The ending songs don't hint at anything. The name is just the name of the song, it wasn't made for Dragonball specifically.

Is the 70 cm squared window a reference to a camera or something or 70 cm film or something? The background is what looks like a film real. I think film is in MM but does the front of the camera correlate to 70cm square window to let in light correctly?

The song is passing along time while the film real is rolling similarly.
