base workflow for Audio+Image to video for Dev model. LOW VRAM as possible.can also generate text to video with audio reference. (switch red boolean node to TRUE)i suggest leaving the prompt alone unless you want to prompt for a specific motion or action to occur.prompt:" Transform this static image into a high-quality video with with realistic facial expressions and realistic motion.Perfect lip-sync to the attached audio.
