ok cool! By googling i found other 2 ways of doing seemless loops:
like:
A)

and like
B)

if A produces the same result as B, i think it would be helpful if we had something like:
Render time selection 2 times (i think i'll request this). And so we could easily do seemless loops for getting the tail in the beggining technique.
the guy in B says the opposite at ~4:38 (

He says it can have different results! i don't see why! can it be true?
Also, Which other techniques exist?
