A Reddit user showcases LTX 2.3 on close-up video generation and says the model is especially impressive on facial detail, subtle expressions, camera motion, and lip sync.
Key takeaways from the post:

- On an RTX 3060 12GB, a 6-second 1080p clip takes about 12–15 minutes to generate
- The author argues the extra time is worth it if the hardware can handle it
- The post includes project files, embedded metadata, and source images, with the sample promoted via Patreon
