veo-frames-to-video_skill

Overview

This skill generates a smooth video bridging a first and last frame using the Veo 3.1 model via fal.ai. It creates interpolated motion and optional audio so you can produce time-lapses, scene morphs, or growth/ transformation animations from two static images. Quick to call from shell, Python, or JavaScript with simple parameters.

How this skill works

You provide a text prompt and URLs for the starting and ending frames. The service uses Veo 3.1 to interpolate frames over a chosen duration, aspect ratio, and resolution, and returns a hosted MP4 URL. Optional audio can be generated to match the visual transition.

When to use it

• Create a time-lapse or day-to-night transition between two photos
• Morph a real photo into a painting or another artistic style
• Animate growth, transformation, or scene changes from a start and end frame
• Produce short promotional clips from before/after product images
• Generate smooth visual transitions for presentations or social content

Best practices

• Use frames with similar camera composition and subject placement for the smoothest interpolation
• Describe the motion and visual changes explicitly in the prompt (e.g., "lights gradually turn on")
• Select longer duration (8s) for complex or slow transitions; shorter durations for quick effects
• Prefer 720p for faster generation and 1080p for higher detail; adjust aspect ratio to match output use (16:9 for landscape, 9:16 for vertical)
• Host input images on a reliable HTTPS URL and verify both are accessible before requesting generation

Example use cases

• Time-lapse cityscape from morning to night with gradual lighting changes
• Seasonal scene change from summer to winter showing leaves falling and snow accumulation
• Interior design demo: empty room transforming into a furnished room
• Botanical growth animation from seed to full plant for educational content
• Portrait morphing from a photograph into an impressionist painting for artistic reels
