Overview
What is Ray2?
Ray2 is a large–scale video generative model capable of creating realistic visuals with natural, coherent motion. It has a strong understanding of text instructions and can take video as input.
Ray2 exhibits advanced capabilities as a result of being trained on Luma’s new multi-modal architecture scaled to 10x compute of Ray1. Ray2 marks the beginning of a new generation of video models capable of producing fast coherent motion, ultra-realistic details, and logical event sequences. This increases the success rate of usable generations and makes videos generated by Ray2 substantially more production-ready.
Text-to-video generation is available in Ray2 now, with image-to-video, video-to-video and editing capabilities coming soon.
How does RAY2 differ from previous versions like Ray1.6?
Ray2 is a large–scale video generative model capable of creating realistic visuals with natural, coherent motion. It has a strong understanding of text instructions and can take video as input. In short:
Realism & Quality: Ray2 delivers lifelike textures, smooth camera work, and action-packed scenes.
Video Length & Resolution: Supports up to 10-second clips at 720p (Ray1.6 offered lower resolutions and shorter length).
Streamlined Workflow: Eliminates the slow-motion playback issues sometimes seen in Ray1.6.
These improvements mean faster, more realistic results for creative projects and professional applications.
Product Features and Functionality
How do I get access to Ray2?
If you have a paid Dream Machine subscription, log in to your Dream Machine account at dream-machine.lumalabs.ai and select Ray2 from the Description Mode in the Prompt Field at the bottom of the Board or Ideas page.
Why can't I use Keyframes on Ray2?
Currently, Ray2 only supports text-to-video generations. Using keyframes will default to Ray1.6
Can I create 1080p videos?
At launch, our video model only supports 540p and 720p.
Does Ray2 support Keyframes?
Ray2 is currently text-to-video only. Using keyframe images defaults back to Ray1.6. If you need image-based keyframes, Ray1.6 remains available.
Can I create 20s videos?
You can only select between 5s and 10s, to create a longer video you can select “Extend”.
What is the typical generation speed?
The time it takes to generate content in Dream Machine can vary based on several factors:
Simple Clips (5–10 seconds): Often ready within 45-60 seconds of generation time.
Extended/More Complex Clips: May take 45–60 seconds, especially when generating multiple videos at once.
Why is Ray2 trained directly on video data?
This approach allows the model to learn natural motion, realistic lighting, and physically accurate interactions between objects or characters—leading to more authentic video output.
Is there a limit for extended video?
Currently there is a cap at 30s.
Can I create one video at a time?
Yes! You can absolutely create one video at a time, go to the Ideas page to create individual videos and single videos and write the prompt you would like to see.
How can I create a portrait size video?
You can select the size of your photo on the drop down menu. We have 9:16 and 3:4.
How do I make my videos loop on web and iOS?
You can make your videos loop in both the app and on the web version, though it looks a little different.
For iOS: You’ll find “Loop” in the prompt tray by tapping the star icon. Navigate to the far right and choose “Loop” under the “Playback” feature. Here you’ll also find an array of other tags organized in “Shots”, “Camera Angle”, “Style”, and “Lighting”. Tapping a tag will add it to your prompt.
For Web: The prompt tray on the web version looks a little different. Make your generations loop by simply writing it into your prompt which works the same way as tapping “loop” in iOS.
Looping doesn’t work. What can I do?
In the new version of Dream Machine, the Loop feature only works in the Board page. If you are in the Ideas Gallery, switch to Boards and prompt there. If you’re on the web version, just include the word “loop” in your prompt and consider using it both at the start of your prompt "looping video of..." and at the end to reinforce the idea.
If you keep experiencing difficulties it could be due to:
Prompt Quality: Looping works best with descriptive and specific prompts or when starting with an image.
Generation Issues: Refer to Luma Labs’ troubleshooting guide for stalled or incomplete generations, such as checking your internet connection, simplifying prompts, or ensuring sufficient credits.
Tech: Try logging out and logging in again and starting a new board if the same issues persist. You can also do a hard browser reset with Shift/F5 and if you’re in the app, delete it fully and reinstall.
Technical Limitations
Are there any current restrictions on video length or resolution?
Ray2 can generate videos up to 10 seconds long at 540p or 720p resolution. If you attempt lengths beyond this, the system may revert to Ray1.6 or show an error message.
Are there any current image generation restrictions?
Our limit for images is currently 1080.
Does Ray2 allow 4K video output?
Not yet. Ray2 is capped at 720p. Future higher resolution, if planned, will be announced on our website.
What happens if I try to upload an image as a keyframe with Ray2?
The system automatically switches to Ray1.6. To remain on Ray2, stick to text prompts only.
Is audio generation supported?
Not at this time. You can, however, add your own audio track after downloading your video.
How It Works
How do I create a video from a text prompt?
Log into Dream Machine: Visit dream-machine.lumalabs.ai.
Enter a Text Prompt: Describe your desired video (e.g., “A bustling city at dawn with cinematic camera sweeps”).
Select the Describe option
Choose Clip Length: 5 seconds or 10 seconds.
Select the Model: Pick Ray2 for best realism and advanced motion.
Select video size: 540p or 720p
Generate & Download: Wait for your video to process (10–60 seconds depending on complexity) and then download your file.
Can I create a portrait (vertical) video in Ray2?
Ray2 does not currently allow changing aspect ratios via uploaded images. If you attempt this, you’ll be switched to Ray1.6.
