Plaguekind/Minimax-H3

PlagueKind - Minimax H3 - Workflow - Ease of use

V1.5 Notes

• Added the option for T2V.
• When using T2V, set scale mode of Target Dimension node to Dimensions (WxH) or you will get a square video.
• Added FSR RCAS sharpening, 0.3 strength is very natural.
• FFLF is unreliable at res above 640, don't know why, it's like this on default WF as well.
• Target Dimension node controls the generation size only, refs are passed elsewhere.
• Don't touch the other hidden resize nodes as they only control ref size and are set to max.
• Euler + Linear Quadratic seems to be the best combo with between 15-20 steps.
• I didn't add easy cache because it ruins the quality noticeably,
• If you have time or a powerful card, try heunpp2 sampler. It's phenomenal.
