I saw this movie clip a few years ago, maybe around 2015. It is in color. It is animated but I think it's not use the same animation style of common Japan anime. It has no subtitle or any dialogue when I saw it. So, it could be a trailer too.
Here is some detail about the movie clip.
There is this main character ( I think), the Kid, standing on a cliff and see some spaceships battle. Something then launched from the spaceship and the Kid start chasing it using his flying motorcycle.
After he got there, it turn out it is a safety pod with a goddess inside ( she wears a divine like robe and she floats), then they are attacked by the previous space ship. It shoots laser and sent robot swarms to destroy them. The Kid grab the goddess and start to run away.
After some chasing through caves and canyons one of the robot successfully destroy the flying motorcycle. After the Kid recover from the explosion, there is this big bad robot with giant weapon trying to chop him off. Before the weapon touch the kid, the robot get attacked by the goddess using sort of laser. Then, many more of the spaceships appear from the sky above and the clip ended.
