I want to export an animation,
anim = Animate[Plot[Sin[x + a], {x, 0, 10}], {a, 0, 5}, AnimationRepetitions -> 1, AnimationDirection -> Forward]
then export it
Export["animation.gif", anim]
the outputs loops. $a$ runs from $0 \to 5$ and then from $5 \to 0$ when I explicitly instructed that it should only repeat once and only go forward. I've tried other output file formats and all of them looped.
Appreciate any help.
