All the redrawn frames in the new trailer for Dragon Ball Super: Beerus. Some frames were completely redrawn, others had their lighting adjusted and had unnecessary details removed.
Yuya Takahashi's corrections were the most interesting because these represented a significant improvement over the original frames. He has also extended his animation for the EP13.
Beerus looks imposing, terrifying and much more serious. The character has been completely rewritten to make him more like his original version in Dragon Ball Z: Battle of Gods.
Ryo Onishi's animation from EP14 will be reused, but it was heavily corrected. He has done other animation work on the series.
Dragon Ball Super: Golden Frieza will be premiered later this year, immediately after Dragon Ball Super: Beerus concludes. It's still in post-production, but we'll probably see a new teaser in a few months.
