<h2 id="simply-advanced-minimax-h3-workflow-by-altoiddealer">Simply Advanced - MiniMax H3 Workflow by altoiddealer</h2>This workflow was built from the ground up by myself working daily over the course of 2-3 weeks, aiming to be well structured, expandable, and easy to use without sacrificing any functionality.<h3 id="new-in-v1.5:">New in v1.5:</h3>Seamless Continuation has been replaced with Seamless Extension<ol><li>Slices off X frames from your video input(s) to set Video/Audio guide(s).</li><li>MiniMax H3 generates Video/Audio which begins and/or ends with those sliced inputs.</li><li>The workflow stitches the result with the original video input(s) using configurable overlap blending strategies.
