I’m getting a 5v 30a psu in the mail shortly so will try to see if that helps, but I doubt it because under “effects configuration “in Hyperion I’ve set an effect at 50percent and 25 percent brightness and it still stopped at the same place, so this tells me power may not be an issue.
How can I fix the early stoppage?
I can only play with the brightness in the effects config screen, is there a way to change the brightness of the leds with regards to the images it captures in screen?
How can I fix the orientation of the leds so it accurately represents what’s in screen?
As pclin suggested, I would also recommend injecting power at the end of the strip as well. The bigger power supply is great but the issue could be voltage drop which more amps or less brightness won't fix. Basically the resistance of the strip lowers the voltage as the power travels along it and at a certain distance it's no longer enough to power any more LEDs. If you have a multimeter you can check your voltage where the LEDs stop but if not, you can use the effects to set everything to solid white. If you see that the LEDS are turning reddish towards where they stop lighting up, that's a very clear indication of voltage drop as well.
As far as changing the brightness, you should be able to that in the Image Processing tab and you may also have the option to adjust brightness in your grabber/capture settings tab.
Regarding the LED layout/orientation, if it looks correct in the LED layout screen and things look as expected in the live view then it should be fine so my guess here would be that the strip isn't getting a good enough data signal. I know you mention this version of the LEDs should support 3.3v signal but a level shifter may be needed. If you can apply effects and the LEDs respond but don't look right, that could also point to the data signal being the issue. Unfortunately I can't say for sure but that's what it seems like to me.
