About Moonvalley

📸 Image-to-Video
Single still images—or keyframes—can be used to generate videos with Marey's Image-to-Video control.
Here's a breakdown of the inputs you'll need for Image-to-Video:
- Prompt: This is where you'll write your prompt in the Prompt description box. Be descriptive about camera details (e.g. 35mm, handheld shot), scene or environment, subjects and action of your video. Prompts with at least 50 words provide best results.
- Image URL: Browse and select an image to use as a starting frame for your video.
- Additional Settings: There are a number of additional settings to customize your generations including dimension size, duration, and seed value.
- Dimension: Select your preferred video dimension from the drop down menu. By default, videos will be 1920x1080.
- Duration: Select either five or 10 second video output. By default, videos will be five seconds.
- Negative Prompt: Add or remove negative prompts to help guide the model away from undesirable results.
- Seed: Select your desired seed value. Seed determines the randomness and different possibilities of each generation. By default, seed will be set to '9'. Use '-1' for a random seed value.
🚀 Quick Start Guide
Follow this quick start guide for using Image-to-Video on fal. It will walk you through the inputs you'll need to start generating and how to export within a few minutes.
- Create a detailed prompt in the description box. Read through Marey's prompting best practices before generating.
- ✅ Do's:
- Aim for a minimum of 50 words of detail
- Use our recommended prompt structure outlined in the best practices document (e.g. [Camera Movement] + [Scale/Perspective] + [Core Visual] + [Environmental Details] + [Lighting/Technical Specs])
- ❌ Don'ts:
- Add negative prompts into your prompt description—use the Negative Prompt field mentioned below.
- Add an image URL. Click 'Choose' and use the file explorer to find your desired image. This will serve as the starting frame for your new generation.
- Click ‘More’ on Additional Settings to expose more inputs for your generation.
- Set your video's dimensions. Click on the dimensions dropdown menu and select your desired size (1920x1080 is the default).
- Pick a duration. You have the option of five or 10 second videos.
- Include negative prompt words. Marey is pre-loaded with negative prompt words to help direct the model away from unwanted results. Add or remove words as needed.
- Select a seed value. Seed determines the randomness and different possibilities of each generation. By default, seed will be set to '9'. Use '-1' for a random seed value. We'll switch this to -1 for now.
- Click 'Run' to start your generation.
Review and Export
By default, the results tab will show you a visual preview of your video once processing has finished. Make sure that you're satisfied with your video.
- If necessary, make adjustments to your prompt and settings and then run your video again. Running the generation again with a seed of -1 will create a new video from a random seed value.
Click the 'Download' button for an MP4 of your video once you’re satisfied with the results.
- Optional: Select ‘JSON’ from the results drop down menu. This will give you a unique “url” link to copy and paste into a browser for download (an easy option to quickly share your video with others).
