ffmpeg \
  -i iphone884.mp4 \

  -vf "scale=512:-1,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" \
  -ss 00:00:03 -to 00:00:06 \

  -i iphone884.mp4 \
  -r 15 \
  -vf "scale=300:-1,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" \

I installed MacOS Sonoma on HyperV, installed XCode and used the following commands to check compiler and SDK versions:

admin@son ~ % xcode-select -print-path
/Applications/Xcode.app/Contents/Developer
admin@son ~ %  xcrun -sdk macosx -find clang
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang
admin@son ~ % clang --version
Apple clang version 15.0.0 (clang-1500.3.9.4)
Target: x86_64-apple-darwin23.4.0
