## What LTX is good at

LTX is the video generation model family from Lightricks, the company behind Facetune and LTX Studio. Both versions on AutoFeed generate audio together with the video.

LTX-2.3 Pro renders at 1080p for the best quality. LTX-2.5 Fast renders at 720p or 1080p for fewer credits, and its 720p clips are among the cheapest with sound in the editor. Both take a text prompt or a starting image and make 6, 8 or 10 second clips in vertical (9:16) or horizontal (16:9) format.

Use it for:

- Longer clips with sound at a low credit cost
- Vertical clips for TikTok and Shorts with audio built in
- Animating an image with ambience or effects

## Prompt tips for LTX

- Describe the sound as well as the picture.
- Use 8 or 10 seconds for slow scenes; keep busy action short.
- Draft on LTX-2.5 Fast at 720p, then render the keeper on LTX-2.3 Pro.

## Frequently asked questions

### Who makes LTX?

LTX is developed by Lightricks. AutoFeed runs it through Replicate, so you do not need an LTX Studio account.

### Do LTX clips have sound?

Yes. Both LTX-2.3 Pro and LTX-2.5 Fast generate audio with the video, and AutoFeed keeps it in the clip it delivers.

### How many credits does a LTX clip cost on AutoFeed?

From 720 credits (a 6 second LTX-2.5 Fast clip at 720p) to 3,200 credits (a 10 second LTX-2.3 Pro clip at 1080p). The table on this page lists every combination of variant, resolution and length.

### How many LTX clips do I get on each plan?

Hobby ($19/month, 15,000 credits): 4 to 20 clips; Pro ($59/month, 60,000 credits): 18 to 83 clips; Ultimate ($249/month, 180,000 credits): 56 to 250 clips. Credits are shared across everything you make on AutoFeed, so clips on other models or faceless videos draw on the same balance.

### Can I try LTX for free?

Yes, once. A new AutoFeed account gets 1,000 free credits with no card, enough for a 6 second LTX-2.5 Fast clip at 720p, which costs 720 credits. More clips need a plan.

### Does LTX on AutoFeed add a watermark?

No. AutoFeed adds no watermark or logo. Each clip is delivered as an MP4 at 1080x1920 for 9:16, 1920x1080 for 16:9 or 1280x1280 for 1:1, ready to download or post.

### Is LTX text to video or image to video?

Both. LTX on AutoFeed accepts a text prompt on its own, or a starting image plus a prompt describing the motion.

### Can AutoFeed post LTX videos to TikTok and YouTube?

Yes, one clip at a time. When a clip is ready you can post it to a connected TikTok or YouTube account straight away, or pick a date and time to schedule it. AI video clips are not a recurring series: the series that write, render and post new videos on their own schedule are the faceless formats (AI slideshows, Reddit stories, Would You Rather, Pick One and Fake Text).
