Can i verbose boot without Checkra1n?

Simply put? No.
See, Verbose Boot on iOS is done like on macOS / OS X via a boot argument or boot flag. The "-v" to be more specific. On macOS, you can edit the NVRAM to pass that argument with just root access (sudo) and possibly SIP disabled. On iOS, iBoot has been ignoring boot args for quite some time now and there is no easy way to fix that. You would need to patch iBoot / iBEC / iBSS to pass the "-v" boot arg to the XNU Kernel so that the Kernel does verbose boot, but that would require an exploit like CheckM8 to be active to load the patched bootchain so you're back to square one. The iPhone would refuse to load your patched bootchain without an exploit to patch the signature checks between the bootchain components, mostly between SecureROM and iBoot.

I didn't think it had anything with SecureROM lol my bad

SecureROM is the first code that runs on the device when it powers on. It checks the next stage after setting up some stuff and passes control to the bootchain. So, it does have to do with mostly anything because if SecureROM says no to iBoot, it's game over.

Respring logo on iOS is a very high-level component and it's not checked for codesign. Mostly just an image.
The same way you can change the .caf file that has the sound the device makes when you plug the charger, and it would persist after a reboot.

Can you upload a verbose boot video to make it a respring logo? xd

You may need to make a gif.

I don't think you can get a very clear image from a shot video. You're better off reconstructing it manually in a photo/video editing software from a boot log.
