LTX 2 Pro: the still is the contract (6s, 8s, 10s, 4K, 6cr)
LTX 2 Pro is image-to-video. If the label is wrong, every second is waste.
LTX 2 Pro is image-to-video. If the label is wrong, every second is waste.
The catalog name is LTXV2 Pro: professional image-to-video with LTXV2. Requires an image. Durations 6s, 8s, and 10s. Max output 4K. Qualities 1080p, 1440p, 2160p. Credits 6. Catalog audio is true. Features: Professional, High-quality, Image-to-video.
4K does not excuse a bad still. It enlarges it.
4K from a plate, 6s, 8s, or 10s
LTX 2 Pro wants a start frame (jpg, jpeg, png, webp, gif, or avif in the schema). Crop that still to the cut. Aspect can be auto (inferred from the image) or 16:9, 9:16, 1:1. Auto is the honest default: the still is the contract, including its ratio.
Prompt the path of motion, not a new room. "The camera holds, steam lifts, she turns a quarter toward us." A negative-prompt field exists; put morphing, extra limbs, and new backgrounds there. 6s is the short cinematic beat. 8s is the listed default-shaped hold. 10s is the long end of this card — not 12s, not 20s. The Fast T2V sibling lists longer durations; this Pro I2V card does not.
If you do not have a still, you are on LTXV2 Text to Video Pro: also 6 credits, also 6s / 8s / 10s, also 4K, also native audio, and it invents the frame. That is a different identity. Do not paste a paragraph into I2V Pro and call the missing jpg a technicality.
The AI image to video tool is the launcher. LTX's roster is Lightricks' video family. Best image-to-video is the ranking.
Native audio on an I2V row
Catalog audio is true, generate-audio default on. A 4K product plate plus a mute prompt can still come back with room tone and a line. Write the sound that belongs to the still — or write quiet, no speech — in the same brief as the motion. Native audio is not only a text-to-video feature here.
Six credits is the catalog rate; the matrix also lists a 4K step at 24 on a per-second resolution dimension, with a floor around 36 credits once duration is in. Read the estimate before you confirm. The title number is the card's 6-credit figure for the SD/HD option. 4K is the reason people open Pro. It is also the reason an unreadable label becomes an unreadable poster.
Six credits is not a text-to-video bargain
I2V Pro is cheap relative to 70-credit rows. That is how teams skip still review. A 1-credit or 4-credit stills pass is still cheaper than 6s of 4K almost. Lock the pack. Then buy 6s at 1080p as a motion check if you want. Then 8s or 10s at 2160p when the motion is the keeper.
Do not use this row to invent a presenter. If the job is a script on a face, that is lipsync. LTX 2 Pro animates a plate you already believe, at 6s / 8s / 10s, with a soundtrack you should have named.
FAQ
What happens if I skip the image on LTX 2 Pro?
You are not on this model. The row requires a start frame. Use the text-to-video Pro sibling, or lock a still first. Every 4K second without a plate is waste.
Is 4K available at 6s, 8s, and 10s?
Those are the three durations on the card, and 4K is the max output, with 1080p and 1440p as quality steps. Pick duration for the gesture, resolution for the delivery. Do not buy 10s 4K to discover the still is wrong.
Does LTX 2 Pro always generate audio?
Catalog audio is true and generate-audio defaults on. A silent prompt still gets a soundtrack you did not choose unless you turn it off or write quiet. Decide the switch and the words.
Why not always use the text-to-video Pro row at the same 6 credits?
Because T2V invents the frame. I2V Pro spends the 6 credits (and the 4K pass) on a still you approved. If the label matters, the still is the contract.
