A 4-minute animated short built with FLUX.1 Dev and LTX-Video 2.3
The post shares a full workflow for making The Crystal Keeper, a 4-minute animated short, and asks for feedback on quality and consistency.
Pipeline
- Scene script
- Character LoRAs trained on FLUX.1 Dev
- First-frame generation with FLUX.1 Dev
- LTX-Video 2.3 image-to-video at 768×512 / 24 fps
- Edge-TTS for per-character audio
- FFmpeg for final assembly
What the creator is seeing
- Some character drift remains even with IPAdapter + LoRAs.
- Occasional flicker and jitter, especially on faces during dialogue.
- The creator is asking whether higher resolution, different guidance settings, or better upscaling would improve results.
- They also want more precise lip sync and audio-driven animation in ComfyUI.
Why it matters
This is a useful real-world example of the current state of AI video production: impressive short-form output, but still fragile on identity consistency and temporal stability.
