Integrating text in trailers is essential for delivering critical information, but common mistakes include using illegible fonts, poor placement, or excessive text that distracts from visuals. Overloading the trailer with text blocks can overwhelm the viewer and disrupt the visual flow. Editors often need to remember that text should be concise, impactful, and complementary to the scenes. Failing to animate text smoothly or synchronizing it improperly with the music can make the trailer feel disjointed. Avoiding these common mistakes ensures that text elements reinforce the trailer's message without overshadowing the cinematic content.
