My laptop only has 6GB VRAM, so I never thought I’d be able to mess with video generation. Then I saw someone using a new LoRA on LTX 2.3 to make two characters talk at the same time—just one image, a prompt, and a custom audio file, and it generates. So I gave it a shot.
This LoRA is specifically trained to improve consistency and lip-sync quality in dual-character scenes, which are exactly the hardest parts in the standard workflow. The tutorial covered a few points: how to generate the starting image first, use Prompt Relay to boost accuracy, make the prompt more obedient, and that the LoRA itself works at 1240×720 but can be upscaled to full HD output.
The tips for dual-character lip-sync were pretty solid. Being able to run on 6GB is really student-friendly, though don’t expect blazing speed.
