This AI Paper Introduces VidChapters-7M: A Scalable Strategy to Segmenting Movies into Chapters Utilizing Person-Annotated Information

Within the realm of video content material group, the segmentation of prolonged movies into chapters emerges as an necessary functionality, permitting customers to pinpoint their desired data swiftly. Sadly, this topic has suffered from hardly any analysis consideration because of the shortage of publicly obtainable datasets.

To handle this problem, VidChapters-7M is introduced, a dataset comprising 817,000 movies which were meticulously segmented into a powerful 7 million chapters. This dataset is assembled routinely by extracting user-annotated chapters from on-line movies, bypassing the necessity for labor-intensive guide annotation.

Throughout the scope of VidChapters-7M, researchers have launched three distinct duties. Firstly, there may be the video chapter technology job, which entails the temporal division of a video into segments, accompanied by the technology of a descriptive title for every section. To additional deconstruct this job, two variations are outlined: video chapter technology with predefined section boundaries, the place the problem lies in producing titles for segments with annotated boundaries, and video chapter grounding, which necessitates the localization of a chapter’s temporal boundaries based mostly on its annotated title.

A complete analysis of those duties was performed that employed each elementary baseline approaches and cutting-edge video-language fashions. The above picture demonstrates an illustration of the three duties outlined for VidChapters-7M. Moreover, it has been demonstrated that pre-training on VidChapters-7M leads to outstanding developments in dense video captioning duties, each in zero-shot and fine-tuning eventualities. This development notably elevates the state-of-the-art on benchmark datasets reminiscent of YouCook2 and ViTT. In the end, the experiments have unveiled a optimistic correlation between the dimensions of the pretraining dataset and improved efficiency in downstream purposes.

VidChapters-7M inherits sure limitations attributable to its origin from YT-Temporal-180M. These limitations are related to the biases within the distribution of video classes which can be current within the supply dataset. The development of video chapter technology fashions has the potential to facilitate downstream purposes, a few of which might have destructive societal impacts, reminiscent of video surveillance.

Moreover, fashions skilled on VidChapters-7M might inadvertently mirror biases that exist inside movies sourced from platforms like YouTube. It’s vital to keep up consciousness of those concerns when deploying, analyzing, or constructing upon these fashions.
