With the surge in network traffic, the homogenization of short video content is becoming increasingly prominent, resulting in low-quality entertainment due to proliferation and infringement. Therefore, recognizing visual homogeneity in short videos is of great significance. Considering the extremely similar dynamic evolution in specific regions from intra and inter-frames, introducing region-aware attention is attractive to achieve homogenization recognition. Therefore, we propose a region-aware spatiotemporal Transformer (RaSTFormer) for visual homogenization recognition, including: (1) a region-aware Transformer encoder is designed to extract multi-region frame-level features from short videos; (2) a multi-layer spatiotemporal Transformer decoder is used to aggregate multi-region frame-level features, generating shot-level spatiotemporal features; and (3) measuring symmetric shot-level chamfer similarity to recognize visual homogeneous content. Specially, we established a real-world video homogenization dataset, BJUT-HCD, and conducted extensive experiments. The proposed RaSTFormer achieved the highest mean average precision (mAP) of 98.13% and a top-1 accuracy of 99.37%, outperforming SOTA methods. The results show that our method achieves competitive performance in visual homogenization recognition in short videos. [ABSTRACT FROM AUTHOR]

Modern mobile technologies that allow the quick creation of short videos provide users with ample opportunities to present their information in public space. Teenagers have become the most active users of new forms of creativity, so their self-presentations on video platforms deserve attention. This study uses content analysis to examine the features of Chinese adolescents' selfpresentation on Douyin, the Chinese TikTok counterpart, and the cultural factors that determine these features. We discovered that teenagers' self-presentation is characterized, firstly, by the creation of a virtual identity based on the real one, secondly, by freedom in the choice of role behavior, and thirdly, by the idealization of their image and various means of its formation. In addition to the impact of social, commercial, and network values, we also found the influence of traditional Chinese culture. Cultural stereotypes formed by upbringing are reflected in the forms of self-presentation (from external style to way of thinking) by the modern younger generation on social networks. We noted the role of celebrity culture in the daily lives of teenagers. In the future, studying the role of Chinese adolescents in the social information system, especially at the stage of changes in their self-perception and self-presentation, seems relevant.

The rapid proliferation of artificial intelligence (AI) technology, particularly the deployment of generative AI in the creation of short videos, has exposed the anachronistic and incomplete nature of the copyright limitations and exceptions (L&E) within the Copyright Law of China. The US jurisprudential approach, characterized by the four-factor fair use analysis and the doctrine of transformative use, has been embraced in China by courts as 'general legal principles'. These principles have been localized within the restrictive framework of the Berne Convention's three-step test. However, the application of these principles to China's burgeoning AI and AI-generated content industry, exemplified by the short video sector, reveals a complex landscape. The purposes behind the utilization of copyrighted works are multifaceted, and the intense rivalry between 'long' and 'short' videos that represent established and emerging giant Internet platform enterprises further muddies the waters in the application of the American 'purpose transformation' concept. A better alternative would be to seek guidance from the Copyright Law of Japan. By grounding decisions in pre-existing, enumerated copyright exceptions, systematically categorizing L&E scenarios, and delineating key considerations for various categories, the judiciary can be steered towards a more nuanced and equitable resolution of individual cases and strike a balance between the interest of copyright holders, Internet users, and the emerging Internet platform enterprises.

Background: The utilization of short videos by individuals often leads to the emergence of information exchange behavior. Previous studies have shown that certain students with psychological disorders exhibit addictive tendencies towards short video-related software. Therefore, it is essential to address the psychology and behavior of college students with psychological disorders while engaging with short videos. This study aims to explore the mechanism of short video information interaction behavior among college students with psychological disorders. Methods: We conducted semi-structured interviews with 30 college students afflicted by psychological disorders in a prefecture-level city in Henan Province, China from September to December 2022. Based on the Grounded theory, we encoded 30 text materials across three levels to explore the mechanism of short video information interaction behavior among college students with psychological disorders, and subsequently build a model framework. Results: The findings of this study suggest that college students with psychological disorders exhibit negative cognition tendencies that can lead to strongly negative emotions, excacerbated by a lack of social support. These adverse factors collectively drive the consumption of short video content in this demographic, providing a virtual environment where they can fulfill their unmet social needs. Therefore, the mechanism governing short video messages interaction among college students with psychological disorders encompasses negative cognitive tendencies, negative emotions, lack of social support, post-video-watching behaviors, and the gratification of social needs within the confines of a virtual environment. Conclusions: This study comprehensively analyzes the motivation and complexity of college students with psychological disorders in short video interaction. Although short videos provide this group with some ways of self-expression and emotional support, they still have a negative impact on their physical and mental health. The short video interaction of college students with psychological disorders is affected by many factors, including their negative cognitive tendencies, negative emotions, lack of social support, post-video-watching behaviors, and the gratification of social needs within the confines of a virtual environment. These findings deepened our understanding to the mechanism of short video information interaction behavior among college students with psychological disorders, also provided us with guidance on facilitating the proper use of short video and maintaining the mental health. In future researches, researchers can discuss more about intervention measures to help this demographic cope with the challenges from short video interaction. [ABSTRACT FROM AUTHOR]

As one of the most prevalent we-media, short video has exponentially grown and gradually fallen into the disaster area of infringement. Video fingerprint extraction technology is conducive to the intelligent identification of short video. In view of various tampering attacks, a short video fingerprint extraction method from audio–visual fingerprint fusion to multi-index hashing is proposed, including: (1) the shot-level fingerprint of short video is extracted by audio–visual fingerprint fusion after analyzing the consistency to eliminate the uncertainty at the decision-making layer, in which the visual fingerprint is generated by R(2 + 1)D network, and the audio fingerprint is combined by extracting audio features with masked audio spectral keypoints (MASK) and convolutional recurrent neural network (CRNN); (2) the shot-level fingerprints are assembled into the data-level fingerprint of short video by constructing the data-shot-key frame relationship model of data structure; (3) the short video fingerprint is matched by measuring the weighted Hamming distance by creating the multi-index hashing of the data-level fingerprint. Five experiments are conducted on the CC_Web_Video dataset and the Moments_in_Time_Raw_v2 dataset, and the results show that our method can effectively raise the overall performance of short video fingerprint.

With the promulgation of the "rural revitalization" initiative, China has been promoting the marriage between technology and rurality to chart a digital future for what is christened "a new countryside." Rural revitalization is not simply a socio-economic project but a profoundly ideological one, which choreographs a socio-spatial order, fashions an aspirational rural subjectivity, and realigns imaginaries of rurality. This article examines the role of short video in fostering an emergent rural performativity in line with official ideology through idyll-icized displays of rural lifestyles and landscapes, which are loaded with affective and ideological connotations. A scopic contact zone is thus carved out between rural vloggers and urban viewers, one characterized by mutual appropriation and strategic differentiation. This article foregrounds the limitations of this urban-rural contact zone and its immanent "cruel optimism," while advocating a kind of radical utopia to enable imaginations of the alternative futures of digital rurality.

Background: Short videos are becoming increasingly popular globally, and users are devoting more time to viewing them. However, few studies have examined the characteristics of short video content and the technical features that are related to media use. The present study developed a model to explore the influence of technological affordances on short video usage and considered innovation in terms of format, setting, and content. Method: A total of 496 viewers of short videos from China were surveyed. The participants completed 31 Likert-scale items. The study used maximum likelihood estimation modeling. Results: The results revealed that perceived novelty and content value (entertainment and irritation) affected immersion positively, consequently influencing intentions for reuse and recommendation. The ease of navigating an application, narrative structure, and information value had no significant effect on immersion. Conclusion: These findings have confirmed that perceived situation affordance and the affective affordance of short videos in digital environments that are managed by intelligent algorithms. It is necessary to analyze the potential impact of different affordances specifically. [ABSTRACT FROM AUTHOR]

With the popularity of 5G and the rapid development of mobile terminals, an endless stream of short video software exists. Browsing short-form mobile video in fragmented time has become the mainstream of user’s life. Hence, designing an efficient short video recommendation method has become important for major network platforms to attract users and satisfy their requirements. Nevertheless, the explosive growth of data leads to the low efficiency of the algorithm, which fails to distill users’ points of interest on one hand effectively. On the other hand, integrating user preferences and the content of items urgently intensify the requirements for platform recommendation. In this paper, we propose a collaborative filtering algorithm, integrating time context information and user context, which pours attention into expanding and discovering user interest. In the first place, we introduce the temporal context information into the typical collaborative filtering algorithm, and leverage the popularity penalty function to weight the similarity between recommended short videos and the historical short videos. There remains one more point. We also introduce the user situation into the traditional collaborative filtering recommendation algorithm, considering the context information of users in the generation recommendation stage, and weight the recommended short-form videos of candidates. At last, a diverse approach is used to generate a Top-K recommendation list for users. And through a case study, we illustrate the accuracy and diversity of the proposed method.

With tourism short video platforms’ increasingly fierce competition, retaining existing users and improving engagement has taken on greater theoretical and practical significance. Based on the self-system model of motivational development, this study, involving an empirical analysis of 252 user data samples, establishes a research model to determine how the use contexts affect users’ psychological process and finally lead to behavioral engagement. In particular, four use contexts of tourism short video platforms are proposed—namely, information acquisition, leisure and entertainment, attention obtainment, and social interaction. Different use contexts differ in the degree to which they satisfy users’ three psychological needs, thus influence their attitudinal engagement and behavioral engagement. The research results can provide theoretical and practical references on how to improve user engagement toward tourism short video platforms. [ABSTRACT FROM AUTHOR]

It has been found in many cases that consumers are prone to exhibit impulsive buying behavior that is manifested as being immediate, emotional, and irresponsible especially under short video scenario. Supported by the customer inspiration theory, this study explores the psychological mechanism underlying impulse purchase in short videos that differentiates the traditional web shopping by the strong sense of presence in short video marketing. On the basis of a questionnaire survey and three laboratory experiments, this study examines the relationship among presence, customer inspiration, and impulse purchase intention. The empirical results point to the fact that social presence, co-presence, and physical presence have significant positive effects on impulse purchase intention, and customer inspiration mediates the effect of social presence, physical presence, and co-presence on impulse purchase intention. Furthermore, it is indicated that social and co-presence have stronger influences on impulse purchase intention than physical presence, thus proving a stronger effect of social factors on impulse purchase intention than physical factors in short video environment. The research results testify the impact of presence on consumer behavior in the upgrading short video marketing and provide valuable reference for marketing strategies to shorten consumers' decision-making time in short video purchase.

Media-triggered mental disorders are common when people experience traumatic events. However, few studies have examined the underlying mechanism of how viewing disaster-related short videos triggers psychiatric reactions among non-exposed populations in the context of today's media ecology. Moreover, limited studies have employed psychological network analysis to comprehensively disentangle the associations between diverse forms of media exposure and psychological symptoms. To fill these research gaps, we conducted a survey on a non-exposed population (N = 516) during the 2021 Henan floods to test the effects of short video exposure on its mental status. Short video exposure behaviors were measured under 12 different scenarios, and the participants' mental status (i.e., depression, anxiety, and post-traumatic stress disorder [PTSD]) was measured using the nine-item Patient Health Questionnaire (PHQ-9), seven-item Generalized Anxiety Disorder (GAD-7) scale, and PTSD Check List-Civilian version (PCL-C). We employed both correlation and psychological network analyses to make estimations. The descriptive results revealed that short video exposure behaviors among almost all scenarios were positively associated with the scores of PHQ-9, GAD-7, and PCL-C. The network analysis revealed that both depression and anxiety were associated with the "Support (SVP)" scenario, whereas PTSD was directly linked to the "Help Seeking (SVP)" scenario. Among the three networks, "Help Seeking (SVP)" was the most central among the 12 scenarios of short video exposure. The central symptoms for depression, anxiety, and PTSD were "Concentration," "Relax," and "Reliving Trauma," respectively. The shortest paths between the central short video exposure item and central symptom among the three networks consisted of only two or three steps. This study's findings could assist researchers and policymakers in undertaking novel disaster-related practical activities worldwide. [ABSTRACT FROM AUTHOR]

This study aims to determine the relationship of educational video production with educational video consumption and academic performance and identify the views of pre-service literacy teachers about the process. It has a convergent parallel mixed-method design. An eight-week two-stage experimental process took place with the participation of 53 pre-service literacy teachers. At the first stage of the process, the pre-service literacy teachers produced argumentative monologues. Next, at the second stage, they created short videos composed of argumentative monologues. The data collection tools were the Video Evaluation Form, the Taxonomic Test to Measure Success, the Scale of Adults' Levels of Acceptance and Usage of Video-Sharing Websites for Educational Purposes, and the survey. According to the results of this study, the process of learning by producing short videos enhanced academic success and supported in-depth learning. The success levels of the participants in topics on which the videos were produced were significantly higher than their success levels in topics on which the videos were not produced. Even if the pre-service literacy teachers were challenged at certain points during the process of learning by producing videos, they thought that the video production prepared them for their professional future with diverse perspectives. On the other hand, only half of the participants had positive viewpoints about the process. The presence of negative viewpoints reduced the quality of the videos that were produced. However, academic success was not affected by this situation. There was no significant relationship between the preservice literacy teachers' educational video consumption and production behaviors.

The prevalence of We-Media short videos has attracted emerging independent fashion designers (EIFD), a new force in the fashion industry directing their brand promotion to We-Media for amassing online followers. However, compared to famous content generators, EIFDs' creative, design-based visual appeal has not provided them with the significant edge. The former's success is admittedly supported by the platform backstage algorithm. Yet, the content is the cornerstone for building relationship between the sender and the reception. The authentic perception of the content is one of the basic appeals for which the audience chooses to follow the source. Therefore, with the EIFD short video as the research content, this study is established from the audience's perspective to understand the different dimensions of their authentic perceptions of EIFDs short video. The study was conducted mainly in the form of the Q method. The collection of 52 Q samples were realized through the Focus Group Interview and literature review on multidimensional authenticity. Thirty-six subjects participated in the sorting of the Q-sets. Finally, four dimensions of audience authenticity perceptions of EIFDs were derived: 'ingenuity', 'relevant', 'transparent', and 'experiential'. The corresponding short video content design strategies are suggested for effective communication of EIFDs and their personal brands. [ABSTRACT FROM AUTHOR]

The increasing number of short videos have permeated people's daily life and played a vital role in information dissemination. However, the burgeoning video's form brings challenges to discern the key features and improve the dissemination's effect of short videos in affecting user engagement. Additionally, modeling the composition of likes, shares and comments as a response variable is essential in analyzing user engagement. Aiming to aggregate information from short videos and offer the quantitative method to advance the previous qualitative analysis on user engagement structure, we establish a framework for modeling multimodal data embedded in a short video. Building on deep learning and text mining method, we extract features from videos' acoustics, textual, and visual data as high-dimensional variables. Then, we propose a new variable screening method for compositional response to reduce the vector dimensionality. These variables and other numerical variables are integrated into multiblock partial least squares to analyze the importance of each variable block. The numerical results show the effectiveness of the proposed method. Furthermore, the proposed method is empirically applied to the TikTok platform administered on various kinds of short videos to show the key factors that determine user engagement structure. Theoretical contributions and pragmatic implications to be gleaned from our research model and its subsequent empirical validation are discussed. • A variable screening method is proposed for regression with compositional response. • Deep learning is employed to extract features from multimodal data of short videos. • A multiblock data analysis for video data with model explanatory power is proposed. • The structure of user engagement can be explained by identified key features.

In the context of the rapid development of online shopping, enterprises and consumers realized the importance of an effective online short video display. However, academics rarely explored the content of a short video display and its impacts on consumers' perceptions. This paper discusses the impacts of this display form on consumers' perceived quality via questionnaires and scenario experiments based on the existing literature and theories. A short video of clothes was the main research object. We used an experimental design that included 2 (time: long, short) × 2 (display perspectives: overall, specific) × 2 (scenarios: outdoors, indoors) groups of experiments, for a total of eight groups of scenario experiments, to verify our hypotheses. The results reveal that the short video display makes consumers have a higher perceived quality compared with the long video display. Compared with a video that only includes an overall view of the product, a video that provides both an overall view and the details of the product makes consumers have a higher perceived quality. Consumers were found to have a higher perceived quality of products shot outdoors compared with products shot indoors. [ABSTRACT FROM AUTHOR]
