MiniMax H3 R2V: How to Match Reference and Target Video Resolutions?
theshield99 · reddit · 2026-08-10
A developer raised questions regarding the matching of resolution and aspect ratio for reference assets while using the default R2V workflow in ComfyUI.
Using a 2053×2700 selfie as a reference image and targeting a 9:16 aspect ratio at 0.4 megapixels (480×864), the author wonders: to achieve the best character consistency, must the reference photo be cropped to 9:16 and downscaled to 0.4 megapixels? Furthermore, when using both a reference photo (for appearance) and a reference video (for motion) simultaneously, do their aspect ratios need to be aligned if they initially differ?
