H3 Video Quality on 5070Ti: Smudged Faces Despite Every Workflow and Setting
ApplicationCreepy987 · reddit · 2026-09-22
A user shares sample outputs and a full structured prompt for H3 reference-based image-to-video on a 5070Ti (16GB VRAM), detailing persistent quality issues: smudged faces and low-detail brickwork on a 'woman walking down a UK street' prompt.
- Tried the official template and many community workflows, models from bog-standard to singularity, eros, pinkcherry
- Tested with/without turbos, realism loras, single-pass vs latent upscale passes, steps 4–25, countless resolutions and aspect ratios — results barely change
- Suspects showcase videos on civitai are cloud-generated with much larger models
- Includes a full segmented prompt (style/subject/summary/retention/detaileddescription) usable as a reference-to-video template
Takeaway: there may be a hard quality ceiling for this workflow on consumer 16GB GPUs.
