Luma app glossary

A few useful terms

Model: the Generation engine, such as Ray 3.2, Seedance 2.5, GPT2.0, or Kling 3.0.

Panel: the interface for a Model, including its Instruction field, reference assets, Resolution, Aspect Ratio and other Settings. In this guide, “Prompt Field” means the field labeled “Instruction” in each Panel.

Generation (or Render): the resulting image, generated video or audio asset.

Job: a Generation or processing request that produced a result.

Prompt: This is simply the description of your scene, the characters, and action in the scene. It can be long or short. Use visual descriptions only, use active verbs. Be clear and concise.

Agent Chat Window: The closeable, repositionable chat window that starts on the right of the screen, open and waiting. This is where you chat with the AI inside Luma, just like you would with ChatGPT, Gemini, Grok or Claude. You can tell the Agent to do anything you could do manually in the workspace, and so much more. You can open additional chat windows if you want a clean contextual memory state.

StartFrame/EndFrame: These are images that become the start or end frames of your video. The system will generate motion based on these frames. You can use one or the other or both or none. Keep in mind that sorting out composition and characters is much cheaper in images than it is in video. I strongly encourage you to make at least a StartFrame before making your video.

Aspect Ratio. This is the ratio between the width (the first number) and the height (the second number) of a video or image. Images and videos can have dimensions in pixels (1920x1080) but you can also define them as a ratio (16:9). 1920x1080 is a 16:9 ratio (16 units wide by 9 units of the same size high) but 960x 540 is also a 16:9 ratio. A ratio does not determine size, only the shape. A square image or video would be a 1:1 Aspect Ratio. A video for Instagram would be a 9:16 Aspect Ratio.

What is that “p” for in 540p or 1080p?

The “P” stands for Progressive. For now it simply means for every frame in your video there is one image. All generative video engines work in Progressive format. Luma works at 24 frames per second (FPS) which is a standard film frame rate. If you want to go down the rabbit hole (this will be funny once we get to the project), go and look up “Interlaced video” for the opposite example of Progressive video.
