Recent years have seen a significant increase in video content creation and
consumption. Crafting engaging content requires the careful curation of both
visual and audio elements. While visual cue curation, through techniques like
optimal viewpoint selection or post-editing, has been central to media
production, its natural counterpart, audio, has not undergone equivalent
advancements. This often results in a disconnect between visual and acoustic
saliency. To bridge this gap, we introduce a novel task: visually-guided
acoustic highlighting, which aims to transform audio to deliver appropriate
highlighting effects guided by the accompanying video, ultimately creating a
more harmonious audio-visual experience. We propose a flexible,
transformer-based multimodal framework to solve this task. To train our model,
we also introduce a new dataset -- the muddy mix dataset, leveraging the
meticulous audio and video crafting found in movies, which provides a form of
free supervision. We develop a pseudo-data generation process to simulate
poorly mixed audio, mimicking real-world scenarios through a three-step process
-- separation, adjustment, and remixing. Our approach consistently outperforms
several baselines in both quantitative and subjective evaluation. We also
systematically study the impact of different types of contextual guidance and
difficulty levels of the dataset. Our project page is here:
