The Vidu Q2: FLF2V workflow is designed to create seamless video transitions between a set of start and end frames, incorporating cinematic camera movements and maintaining multi-subject consistency. This workflow leverages the Vidu Q2 model, which is specifically optimized for generating high-quality video content from static images. Key nodes in this workflow include the LoadImage node, which imports the initial and final frames, and the Vidu2StartEndToVideoNode, which processes these frames to generate a video sequence that smoothly transitions between them. Finally, the SaveVideo node is used to export the resulting video into a usable format. This workflow is particularly useful for creators looking to add dynamic transitions to their video projects without the need for extensive manual editing.
