Step 1 – Drafting the Prompt
Begin by navigating to Text/Image to Video in your Dashboard.
From here, make sure that Gen-3 Alpha or Gen-3 Alpha Turbo is selected from the dropdown in the top left corner.
Text Prompts
Gen-3 Alpha can create highly detailed videos with complex scene changes, a wide range of cinematic choices, and detailed art directions. A descriptive yet clear prompt is key to generating a great video.
Add a descriptive text prompt that conveys the camera angle, subject, scene, style and movement to generate your video. Check out our Gen-3 Alpha Prompting Guide for ideas and more prompt examples.
Below are prompt examples along with their respective outputs:
| Prompt | Output |
| A dramatic zoom in on the face of movie villain as he raises an eye brow and the lights shift, casting an eerie red glow across him. Evil villain lair, 1980s spy movie, cinematic, 35mm film, dynamic movement. | |
| A sci-fi-like action chase scene, FPV hyper-speed fly through multiple locations. Racing through asteroid fields, through a dense clouds, through a complex system of desolate landscapes. Dynamic motion, dynamic blur, timelapse, 30x speed, cinematic, muted color palette. | |
| Dynamic motion, 30x speed. Camera follows a translucent white plastic grocery bag with bold red letters printed on it that read "THANK YOU" as it flies organically in the wind of a desert. the slightly opaque bag undulates in the wind, maintaining the bold red "THANK YOU" text printed on it. |
Image and Text Prompts
Input images are optional in Gen-3 Alpha, but required in Gen-3 Alpha Turbo. Input images will act as the first frame of your video by default.
You’ll be prompted to crop your input image if it is not in a supported resolution.
Include a simplistic text prompt to guide the output of your video. Instead of describing what is in the image, focus on describing the camera, character, and scene movement you'd like in the output.
Step 2 – Configuring the Settings
Gen-3 Alpha has a few additional settings that you should review before starting your generation.
Frame Placement
You can choose if you'd like your input image to act as the first or last frame in Gen-3 Alpha. Please note that you cannot currently upload multiple images to indicate both a first and last frame.
Fixed Seed
Using a Fixed Seed will allow you to create similar generations. This is unchecked by default to give you a wide variety of results.
Copy and paste the seed of a previous output if you'd like to receive generations with similar style and movement. Pasting the seed will automatically check the box.
Remove Watermark
Checking this box will remove the Runway watermark from your output. Make sure this box is checked to generate without watermarks.
Step 3 – Generating the Video
After drafting your text prompt and configuring your settings, you're now ready to generate your video.
You can choose between a 5 or 10 second duration for your output with the duration dropdown near the Generate button. Generative Video defaults to 10 second generations.
Your generations will be scrollable through your session as you continue to generate. You can also access completed videos in your Assets, where they will save to the Generative Video folder by default.
Edit Time
Clicking this button will allow you to edit the duration and speed of your generated video, as well as reverse it.
To trim your video, drag either end of the timeline below the generated clip inwards. You will see the new duration of the clip update automatically as you drag.
To retime your video, move the Speed slider. Moving the slider to the left will slow the clip down; moving it to the right will speed it up. The default setting is 100%, which is your clip’s original speed.
To reverse your video, toggle on the Reverse button.
Step 4 – Extending the Video
Completed Gen-3 Alpha and Turbo generations can be extended up to three times to create a longer video. Gen-3 Alpha videos can be extended to a maximum of 40 seconds, where Turbo generations can be extended to a maximum of 34 seconds given that the original video was 10 seconds.
To extend a video, click the Extend button beneath an output in your session. Alternatively, you can extend an existing generation by opening it through your Assets and clicking Extend video.
The last frame of the video you’re extending will automatically populate as the input.
Add a new text prompt to indicate what should happen in the extension. Extensions are similar to Image to Video generations, so try keeping your prompt focused on camera, character and scene movement.
You can choose between a 5 or 10 second extension before generating in Gen-3 Alpha. The Turbo model offers 8 second extensions. Please note that extension costs will be the same as the pricing of the model used to generate the original video. The model cannot be changed before an extension.
Click Extend to begin the extension. If you’re happy with the extended output, you’ll be able to follow these steps up to two more times to create a long video.
