Thumbnail Requirements
Upload a custom thumbnail if needed (JPG/PNG format, under 5 MB)

Mobile Optimization
Keep important visuals/text within the safe zone (centered area) to avoid cropping
Include subtitles or captions, as most videos autoplay muted
Design for attention within the first 3 seconds
