But this post from nugglets was very enlightening. While we are crunching numbers here, we're forgetting something obvious: It's all paper chemistry - Nothing is impossible and everything is perfect. While in theory and supposedly on dummy targets. So back to helping the topic starter: Skeith.

Frankly, your video isn't very interesting. It shows a basic black mage rotation and only for a minute worth. But here are some things to keep in mind:
Never cancel a cast for a Firestarter proc.
Never use your firestarter proc when you're about to switch into Umbral Ice (this would be after the 4th or 5th cast)
When you're in Umbral Ice with Firestarter on, use Transpose first (so you're in Astral Fire I). This will double the damage dealt.
Count the intervals when you're getting mp back. You get mp every 3 seconds while in Umbral Ice. Fire III takes about 1,6 seconds to cast (depending on your spell speed) If you time this right, you can cheese in your last MP recovery while Fire III is -just- about to finish
Make full use of Aetherial Manipulation and your procs for movement.

If possible, show us a video of your T8 attempts from your PoV. That'll show us a lot more information rather than your rotation on a dummy.
