There are two kinds of LUTs, 1D and 3D.
The 1D ones are 1024, 4096 and 16384.
Now, in your case we're talking about 3D LUTs.
For 3D, sizes are 17x17x17 (this is just barely acceptable, but I would not recommend it), 33x33x33 (average quality, generally good and widely supported by lots of programs, even the home-user oriented ones). Lastly there's 65x65x65 which is broadcast quality and it's supported by programs like AVID Media Composer and surprisingly also by the Avisynth plugin "cube". As to FFMpeg, it didn't support them when I tried years ago, but users reported on my thread that it now does so it seems that they recently introduced support (where "recently" means 2 years ago) but I didn't have time to test them on FFMpeg yet. As to the title, I do put the title in my matrices and I also put a comment inside that states what it does and who made it (i.e me). As to the ".cube" extension, you're gonna be absolutely fine as it's the most widely supported one. There are also.ilut, .olut, .lut, .3dl, .spi3d, .3dl but again, I would go with a generic .cube as it's the most supported one.
