Open-H3-Regenerate-2K tested: sharper faces but up to 2x generation time
gutster_95 · reddit · 2026-11-01
Reddit user gutster95 tested Open-H3-Regenerate-2K detail enhancement on their MiniMax H3 video workflows, focusing on close-ups of faces.
- Verdict: detail enhancement is fairly good, but skin still has a waxy look.
- Cost: up to double generation times; shots longer than 10 seconds get rough even on a 4090 with 256GB RAM.
- Four comparison videos provided: MiniMax H3 + Spectrum 1MP 50 steps with/without Regenerate, and Pika H3 Flex 0.6MP workflows with/without Regenerate-2K.
