Put on Your Editor Hat
A trailer is an exercise in editing. No matter how carefully you plan your storyboards, a trailer will stand or fall on its editing. Think of compressing the grandiosity of editing an entire feature film into 60 seconds. In a feature film, if a shot lingers for a few seconds too long, you can get away with it. In a trailer, even a split-second of awkwardness can feel like an eternity and instantly lose your audience.
A great trailer has the power to thrill audiences, gain interest and build momentum for its respective feature. Treat your trailer with the utmost care and it may very well help you get to the next level of producing and distributing your very own animated feature film.
