Introduction

Gen-3 Alpha is the first of upcoming models that offer improvement in fidelity, consistency, motion, and speed over previous generations of models.

Gen-3 Alpha Turbo is a faster and more credit-efficient model in the Gen-3 Alpha family that generates faster at a lower cost. The Turbo model is available on all plan levels.

Keyframes allow you to configure the starting, middle, and/or ending frames to create smooth transitions between them in a Gen-3 Alpha. In Gen-3 Alpha Turbo, you can input the first and last keyframe.

This article outlines how to use Keyframes on Gen-3, prompting tips, the available settings, and more.

Step 1 – Selecting the Input Keyframes

Begin by navigating to Generative Session in your Dashboard.

From here, make sure either the Gen-3 Alpha or Gen-3 Alpha Turbo model is selected from the bottom left corner dropdown.

Drag and drop a new image or select an existing image from your Assets to configure your First Keyframe. Selecting the image will populate the Keyframe editor:

If you're in Turbo, click the empty Keyframes to add additional images. You can also drag and drop images here to upload them. 

You can hover each input with your cursor to reveal controls to move or remove a keyframe:

When choosing Keyframe images, keep in mind that the ability to receive the desired transition will be highly dependent on the complexity of your input images:

• Images that share a similar subject, scene, and style will offer more consistent, natural, and smooth results. 
• Images that greatly vary in subject, scene, or style may create more experimental or unexpected results.

With your images uploaded, you’re now ready to draft your prompt.

 

Step 2 – Drafting the Prompt

We strongly recommend including a text prompt before generating. 

You can start Keyframe generations without a prompt, but including a clear description that outlines the desired style of motion will offer more controllability and set your generation up for success.

Try to keep your prompt focused on the motion needed to take your video from the first frame to the last frame.

Below are some examples of first and last frames in Gen-3 Alpha Turbo, the prompt used, and their respective output:

First frame	Middle frame	Last frame	Prompt	Result
			individual blobs of liquid dynamically collide and fuse together to form a single goo creature. dynamic fluid, bouncy, reactive motion. the creature looks around. melting liquid. motion-reactive fluid
			A jellyfish made of cloth floating inside a room
			subject dances ballet. they are made entirely of glitching and flickering tv static.

Step 3 – Generating the Video

After uploading your keyframes and drafting your prompt, you’re now ready to generate your video.

Select the desired duration from the dropdown menu next to the Generate button.

When choosing a duration, it may be helpful to once again consider the amount of difference between the two frames. 

More complex transitions, such as cases where the Last frame is completely different from the First frame, may benefit from the longer 10s duration. This would give the generation more time to smoothly transition between the two inputs.

Alternatively, choosing a 5s duration for completely different keyframes may result in more abrupt changes.

Click the Generate button once you feel content with your chosen settings.

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.
