MiniMax H3 long-video editor stitches Latents for seamless 45s+ one-take videos

A Reddit user recommends a newly released "Mini Video Editor" built on MiniMax H3, claiming it outperforms other recent AI "director" tools:
- Different approach: it saves Latents plus video segments and stitches them, instead of generating one long sequence. The poster's 5090 handles 17s per segment, but total length tested to 45s+
- Character consistency holds throughout; segment joins are seamless with continuous motion, thanks to latent stitching
- Resumable workflow: rendered pieces persist as Latents, so you can continue the next day or revise mid-video pieces and they still fit the motion
- As long as each chunk fits in VRAM, speed stays max even past MiniMax limits, producing a fake one-take video
The original tutorial video only had 443 likes; the poster urges the community to spread the word.
