In trailer editing, one of the most common mistakes is overloading the video with too many scenes, which can dilute the impact of each moment. Editors often need to show as much as possible, but this can result in a chaotic and cluttered trailer. Instead, focus on the most impactful scenes representing the film's essence. Quality is more important than quantity. A trailer should leave viewers wanting more, not overwhelmed by information. Avoiding this common mistake ensures that each scene hits hard and contributes meaningfully to the trailer’s narrative.
