I don't have a clue what I'm talking about regarding this but who knows, I may get lucky.
Ok -- so you've seen videos of neopixel led lights I suppose? Or just a plain red LED flashing?
The problem is that a video camera will see the "hot spot" of the light and it will look lousy -- very unrealistic. Maybe some filters or something can help but someone told me it's unlikely. So let's say you do a simple video of a red flashing led(s). Is there anyway through some sort of software where you could superimpose maybe like a red dot and you could adjust the rate etc ? Do you know what I'm getting at? (Flash animation?) (Which I know nothing about). THANKS.
