In recent years, there has been significant progress in video-and-language (VidL) understanding. This paper conducts an empirical study to demystify the most important factors in VidL model design. The study investigates various factors including spatiotemporal architecture design, multimodal fusion schemes, pretraining objectives, choice of pretraining data, pretraining and finetuning protocols, and dataset and model scaling. The results reveal that temporal modeling, video-to-text multimodal fusion, masked modeling objectives, and joint training on images and videos are critical for good performance on VidL tasks. Based on these insights, the authors develop a step-by-step recipe called VindLU for effective VidL pretraining. The final model trained using this recipe achieves comparable or better results than state-of-the-art approaches on several VidL tasks without relying on external CLIP pretraining. For example, on the text-to-video retrieval task their approach outperforms current state-of-the art by 7.8% on DiDeMo and 6.1% on ActivityNet. The paper also highlights the complexity of modern VidL frameworks by dissecting them along multiple dimensions such as temporal modeling schemes, multimodal fusion modules, pretraining objectives source of pretraining data and number of frames used for pretraining. It is noted that existing studies focused mainly on image based analysis or specific aspects of video modelling but did not cover a broad range of VidL design factors like this work does. Overall this work provides valuable empirical insights into VidL framework design choices and offers a practical recipe for effective VidL pre training . The findings contribute to advancing research in the VidL domain.

In recent years, people have made a lot of progress in understanding videos and language together. They did a study to learn more about how to make models that understand videos and language better. They looked at different things like how the model is designed, how it combines different types of information, and what kind of data it uses to learn. They found that certain things are really important for the model to work well, like understanding time in videos, combining words and pictures together, and training on both images and videos. They used what they learned to create a new way of training models called VindLU, which works really well without needing other types of training. This new approach is better than other methods for finding specific parts in videos or matching text with videos. The study also showed that making these models can be complicated because there are many different things to think about when designing them."
