I know it requires zero effort to open up the project file in the Effekseer editor, but I mean, kawmaaawwwnnnnnn, it's 0.1f effort just record a piece of the screen. :)

So yeah, just a suggestion for everyone. Cheers!

Drifty and tea will have to answer officially,  but I believe that partially the goal of submitting the file is having more animations available for people for the engine, a community effort to create more assets before the engine hits. With a video that means nobody could enjoy your animation in their game. 

Standby for an official answer on this :p

A video will not be considered or judged. If we can't play it on the Effekseer software it's disqualified. Please read rule #2. :)

I didn't mean video only. But at least for the sake of generating actual resources to be later used by people, having a preview of how the animation looks would be nice. If you like it, then download it. It's just for the sake of convenience.
