The short answer
LTX 2 is a fast AI video model built for quick iteration and camera-controlled shots. It renders in seconds rather than minutes and accepts first-frame and last-frame inputs, which makes it well suited to frame chaining. In FXI Studio you use it to draft and direct coverage quickly, then chain shots into a continuous scene.
What LTX 2 is best for
LTX 2 is the fast draft tool. Because it renders quickly, it is the model to reach for when you are still finding the shot: trying a camera move, testing a composition, iterating on timing before you commit a slower, heavier render.
It offers camera-motion control on establishing shots, so a dolly-in or a slow push is something you direct rather than hope for. That makes it a natural fit for the wides that open a scene.
How FXI Studio directs LTX 2
In FXI Studio you pick LTX 2 for a shot and see its cost and duration before committing. You describe the coverage and the camera move; Bezaleel names the lens and framing so the fast render still serves the scene rather than drifting.
Because LTX 2 takes first-frame and last-frame inputs, it is built for chaining. You can steer both ends of a shot, which is exactly what frame chaining needs.
Chaining LTX 2 shots into a scene
LTX 2 was made for this. FXI Studio uses frame chaining so the last frame of one shot seeds the first frame of the next, and because LTX 2 accepts both first-frame and last-frame inputs, the handoff is clean.
You draft the wides fast, control the camera, and chain them into a continuous run of shots instead of a set of disconnected clips.
Step by step
How to use LTX 2 in FXI Studio
- 1Open the studio
Start a new shot in the studio. LTX 2 appears in the model picker with its fast render time and credit cost shown up front.
- 2Describe the shot and camera
Write the coverage and the camera move. Bezaleel names the lens and framing so the fast render still serves the scene.
- 3Set first and last frames
For a chained shot, provide a first frame and, if you have one, a last frame to steer both ends of the motion.
- 4Generate and iterate
Render the shot in seconds, review it, and re-run quickly with adjusted camera or framing until it lands.
- 5Chain into the scene
Use frame chaining so the last frame of this LTX 2 shot starts the next, building a continuous sequence.
Frequently asked questions
What is the LTX 2 AI video model?
LTX 2 is a fast AI video model built for quick iteration and camera-controlled shots. It renders in seconds rather than minutes and accepts first-frame and last-frame inputs, which makes it well suited to frame chaining.
How fast is LTX 2?
LTX 2 renders in seconds rather than minutes, which is why it suits drafting and iterating a shot: you can test a camera move or composition and re-run quickly before committing a heavier render.
Does LTX 2 support camera control?
Yes. LTX 2 offers camera-motion control on establishing shots, so a dolly-in or slow push is something you direct rather than hope for, which makes it a good fit for the wides that open a scene.
Is LTX 2 good for frame chaining?
Yes. LTX 2 accepts first-frame and last-frame inputs, so both ends of a shot can be steered. In FXI Studio the last frame of one LTX 2 shot seeds the next, keeping the sequence continuous.
Is LTX 2 free to try?
FXI Studio is in Open Beta with 65 free credits on signup and no credit card required, enough to draft and chain several LTX 2 shots.
