A Redditor shared a full ComfyUI pipeline aiming for believable "phone footage" AI video and asked what to improve: stills look convincing, but eyes soften and faces drift during video.
Image stage — Krea 2 in ComfyUI
- krea2turbobf16 checkpoint, identity LoRA off, 9:16, ClownSharKSampler, 9 steps, CFG 1.0
- Prompt emphasizes eye-level phone framing, natural skin texture, no beauty filter or heavy bokeh
Video stage — MiniMax H3 Ultra on RunPod
- Text encoder H3 Qwen3-VL 32B NVFP4 AWQ; INT8 ConvRot video VAE
- SelfLiftH3Sampler: Euler/beta, 12 steps with transition at 6, low-res scale 0.75 then h3upscaler to target resolution
- Video LoRA: DMAD v4 step600 at 0.75
- Export 9:16, 24 FPS, 15s H.264; 5 min render on RTX PRO 4500 32GB, no interpolation or face repair
The H3 prompt uses a timeline structure (wide full-body 0–4s, two steps closer 4–10s, slow head turn 10–15s) with fixed camera, deep depth of field, and consistent window light. The author invites critique of what first gives away the AI look.
