💡 Pro Tips for Better Results
Be Specific with Actions
Instead of "person walking," try: "woman in red dress walks confidently toward camera, wind blowing her hair," "character jumps off ledge and lands in superhero pose," "POV shot moving through busy city street at night".
Set the Scene and Mood
Include atmosphere: "neon-lit cyberpunk alley with rain," "golden hour beach sunset with waves," "cozy coffee shop interior, warm lighting," "dark forest with fog rolling in".
Use Multiple Reference Images
When using Image to Video, upload multiple reference images (up to 7) to guide the video generation. The more relevant references you provide, the more consistent and accurate your results will be.
Use Extend for Longer Content
Generate a strong initial clip, then use Extend Video to continue the sequence. This lets you build longer narratives while maintaining visual consistency across segments.
Choose the Right Aspect Ratio
Use 9:16 for TikTok, Instagram Reels, and YouTube Shorts. Use 16:9 for YouTube videos, presentations, and widescreen displays. Use 1:1 for Instagram feed posts. Use 2:3 or 3:2 for creative portrait or landscape compositions.
Match Duration to Content
Use 6-10 seconds for quick social media hooks and looping content. Use 15-20 seconds for scenes requiring more action and storytelling. Use 25-30 seconds for detailed narratives, cinematic sequences, and content that needs more room to breathe.
Define Character Actions
Be clear about movements: "girl reaches out to take coffee cup, smiles, then exits frame," "character turns around suddenly looking surprised," "hands typing on keyboard in close-up".
Use POV Descriptions
Specify perspective: "POV hand comes into frame," "first-person view looking down," "over-the-shoulder shot," "bird's eye view looking down".
