LTX 2.3 Image to Video Pro: the still is the contract (6s, 8s, 10s, 4K, 6cr)
LTX 2.3 Image to Video Pro is image-to-video. If the label is wrong, every second is waste.
LTX 2.3 Image to Video Pro is image-to-video. If the label is wrong, every second is waste.
LTX 2.3 Image to Video Pro is pro-quality image-to-video generation. It animates a still image with a prompt. Supports 1080p/1440p/2160p, 6–20s duration (durations over 10s require 25fps + 1080p), optional audio generation and end-image transitions. Catalog durations on the snapshot: 6s, 8s, 10s. Max output: 4K. Credits: 6. Requires image: true. Audio flag: empty. The image-to-video tool is the run. A text-only prompt is the wrong run.
Pro still needs a plate
Requires image is true. Category is image-to-video only. The 4K you are about to buy will be 4K of whatever you uploaded. A crooked label at 2160p is just a sharper mistake.
Qualities: 1080p, 1440p, 2160p. Ceiling: 4K. Aspects: auto, 16:9, 9:16. Compose the still for the ratio you will ship. Auto is not a third composition; it is a handoff.
End-image transitions are in the description. If you have a last frame, that is part of the contract too. If you do not, do not invent a morph in the prompt that the still cannot support.
6, 8, 10 on the snapshot
The duration field lists 6s, 8s, 10s. The description mentions 6–20s with a gate: over 10s requires 25fps + 1080p. Do not sell a 20-second 4K hero off this page. Sell what the duration array lists: 6, 8, or 10 seconds. Climb only when the action needs the extra beats.
6 credits is the snapshot headline. The matrix is resolution-based per second (SD/HD 6, 4K 24). Treat 6 as the listed row price, not a promise that every 4K 10-second take is 6. Read the row you are actually clicking. Either way, a wrong still wastes every second at every tier.
Audio is empty on the flag; the description says optional audio generation. Prompt the sound if you want it. Do not assume a native bed, and do not assume silence. Optional means you specify.
4K is why the still has to be right
Best 4K AI video model is the ranked cut. Best LTX model is the family cut. The LTX roster is the map. This page is Pro image-to-video: locked still, 6/8/10s, 4K available, 6 credits on the snapshot, optional audio in the copy, empty audio flag.
If the label is wrong, fix the still on an image editor. Then come back. Pro-quality motion of a bad pack shot is still a bad pack shot.
FAQ
Can I run LTX 2.3 Image to Video Pro from text only?
No. Requires image is true. It animates a still with a prompt. No plate, no Pro take.
What lengths are on the catalog row?
6s, 8s, and 10s. The description mentions longer takes under 25fps + 1080p constraints. Do not plan a 20-second 4K deliverable off the duration array.
Is native audio guaranteed?
The audio field is empty. Optional audio generation is in the description. Write the sound you want, including none.
Why does the still matter more at 4K?
Because 2160p makes the label readable. A wrong SKU at 4K is the expensive version of a wrong SKU. Approve the frame, then spend the 6-credit row.
