See below considerations to ensure your content displays effectively across the gate LEDs.

To ensure maximum brand exposure, ensure the logo is visible at all times.
Using the maximum pixel height for logos + text will ensure your message is legible.
Asset height is limited, so where possible avoid a stacked logo/message and use a landscape version.
Use big, bold fonts, italic or thin fonts are hard to read on LED.
Dark background colours are the most effective.
Loop your animation so the start/end points are the same.
Make your message memorable. Often the most memorable animations are the simplest.
