Do you shoot videos in different framerates
Only if I want a slow motion version and a real-time version.
f so, does any sell better than others?
No, not really. If you triple your work (24/25/30) you will not see anywhere near triple the sales... Maybe even the opposite.
Any editor with more than one hour of experience knows that most clips without sound will work at any common framerate. If it's a time lapse or slow motion clip, it doesn't matter at all. You can just speed up or down as you wish since it's not supposed to show real time passing by anyway.
