LTX 2.3 Pro — Frequently Asked Questions
How much does LTX 2.3 Pro cost?
It depends on resolution. A 6-second clip costs 57 credits at 1080p and 228 credits at 4K. Visualix AI prints the exact cost on the Generate button before you commit, and refunds automatically if a run fails.
How long can a LTX 2.3 Pro video be?
LTX 2.3 Pro handles up to 10 seconds in a single pass — selectable lengths are 6s, 8s and 10s. For longer pieces, generate several shots and cut them together in the editor.
Does LTX 2.3 Pro generate sound?
Yes. LTX 2.3 Pro produces synchronised audio alongside the picture — ambience, effects and, where the prompt calls for it, speech. No separate sound pass is needed.
Can I animate my own image with LTX 2.3 Pro?
Yes. Upload a still and LTX 2.3 Pro animates it, and you can supply an end frame to control where the shot finishes. Image-to-video generally gives you far more control over composition than describing the same scene in words.
What resolution does LTX 2.3 Pro output?
1080p, 2K and 4K. 4K is generated natively rather than upscaled, so fine detail is genuinely resolved rather than interpolated.
Can LTX 2.3 Pro make vertical video for TikTok and Reels?
Yes — LTX 2.3 Pro supports 16:9 and 9:16, so you can generate natively vertical 9:16 footage rather than cropping a landscape render.
Do my credits expire?
No. Unused credits expire at plan renewal/expiration. There is no throttled "unlimited" tier and no queue that slows down the more you use it — you see the price of each generation and pay that.
