First of all, you may want to try “fastest”, the code might be slightly smaller.
Second, you might consider version 1.x of the arduino-proffieboard plugin, the “Fastest” option generated smaller code with that one I think.
Embedding movies is usually as easy as just pasting the URL, at least that works with google photos and youtube.
The 3535 strips are 7.2 mm wide, I used a 1/4" square dowel, and ran 2 meters from bottom, over the top and back down. then repeated for the other side. I used a 1" thick walled blade from TCSS with the liner, and the foam wrap. it JUST fits… All strips get power, data runs 2 meters, and jumpered over to the next 2 meters
Not sure that just might be it, I did use the V2 configurator for the base of the config i just added some defines and the props file currently I am at work so i can not test it to see if that fixes it
Also, based on your wiring diagram, I think you actually want SubBladeReverse for every other strip, making it 4 SubBlades total, and alternating,
Something like:
Also, maybe consider a 3rd LED pad in parallel to distribute some of that current?
Lastly, your maxLedsPerStrip might benefit from a bit more buffer space by either adding 20-30% or use #define EXTRA_COLOR_BUFFER_SPACE 20 or 30
