Dropbox Japan K.K. (headquartered in Chiyoda Ward, Tokyo), the Japanese subsidiary of Dropbox, Inc. (NASDAQ: DBX), today announced a case study showcasing Dropbox's use in the DMC World DJ Championships (hereinafter 'DMC'), one of the world's largest DJ battle competitions. This case study highlights how Dropbox, including Dropbox Replay, has enhanced the efficiency and transparency of DMC's judging process by enabling streamlined receipt and management of large volumes of video entries, remote judging, and feedback sharing among multiple judges.

Founded in 1985, the DMC World DJ Championships is the most historic and prestigious DJ competition in the world. Top-tier DJs from over 75 countries participate, competing across technical skills such as scratching and beat juggling, as well as musical composition and artistry. With a branch in Japan, DMC sees strong Japanese participation, with past champions including Japanese DJs like DJ Matsunaga and DJ KENTARO. In 2023, DMC introduced a new 'Wildcard' category to open pathways to the world finals for DJs from regions without local branches. Participants submit videos, which are judged remotely by international judges. Finalists earn the right to compete in the DMC World DJ Championships. Last year, marking its 40th anniversary, the world finals were held in Japan—the first time in Asia. Japanese DJ Fummy won the Classic category, and participants from the Wildcard category also delivered strong performances.

In the Wildcard judging process, entrants upload their videos directly to Dropbox, and 5–9 judges use Dropbox Replay to review 300–400 video entries online. This has enabled secure, easy storage, organization, and sharing of large video files. Judges can now leave timestamped comments directly on the videos. As a result, many previously manual processes have been automated, eliminating time-consuming feedback interpretation and misalignment, significantly improving judging efficiency, and enhancing the quality and transparency of evaluations. Before Dropbox, it took up to four weeks for judges to return feedback; after implementation, this was reduced to as little as three days, cutting judging time by 80–90%.

Dropbox is not limited to storing documents and photos. In music production, where high-quality audio files and large data are common, Dropbox supports master audio files such as WAV and AIFF, as well as DAW project files. It allows access from multiple devices including desktops and smartphones, enabling centralized file sharing, viewing, and permission management among team members, whether in the studio or on the move.

Dropbox Replay is a collaboration tool designed to support teamwork using large files such as videos, audio, and high-resolution images. It enables timestamped comments on video and audio, and its 'Live Review' feature allows multiple users to review simultaneously, facilitating smooth discussions and verification among geographically dispersed team members.

We spoke with Antriks Manaoat, Global Competition Director of DMC World DJ Championships, who has long contributed to the development of the DJ scene, about the changes Dropbox has brought to DMC's management and judging processes, the impact of these changes, and the future possibilities for the global DJ community. Here, we present for the first time in Japan the behind-the-scenes story of how Dropbox supports the world's premier DJ competition.

Trial and Error Before Adopting Dropbox

DMC began using Dropbox for the Wildcard category starting in the 2024 Paris season. In the previous season, participants uploaded their videos to a video platform and sent links via email. The organizing team compiled these links into a shared cloud document, and 5–9 judges reviewed 300–400 videos. Judges individually emailed their scores, resulting in a cumbersome, manual workflow.

Additionally, time zone differences among globally dispersed judges caused persistent delays in feedback collection and coordination.

Even when judges provided feedback such as 'the 10 to 12 second mark of this video is great,' identifying the exact moment in question took considerable time. Given the high stakes of a world championship, mistakes were unacceptable, necessitating meticulous manual checks.

Although attempts were made—such as switching submissions to a web form—the core judging process, especially feedback sharing, remained unimproved.

"It was always messy and chaotic. We were constantly searching through emails—labor-intensive, time-consuming, and overly reliant on brute force. It was stressful for judges, and participants wanted results and qualitative feedback as quickly as possible," recalled Manaoat.

Adopting Dropbox as the Foundation for Global Competition Operations

By implementing Dropbox and using its File Request feature, participants now directly upload their videos to a designated folder.

Reflecting on the adoption, Manaoat said: "Given that different countries and regions use different data-sharing services, we valued Dropbox's universal accessibility. Everyone, regardless of location, can intuitively use it. Among many options, Dropbox is a trusted, universal service accessible to people worldwide—that's why we chose it."

The adoption of Dropbox had a significant impact on operations. "Running a historic world championship demands sophisticated operations. Even before official adoption, many stakeholders were already using Dropbox. The ability to sync Dropbox folders directly to computers made folder access seamless. That made a huge difference. By centralizing our entire system on Dropbox, the quality and speed of collaboration improved dramatically. Finally, we felt our operations had truly gone digital," said Manaoat, emphasizing Dropbox's major contribution to operational efficiency and collaboration.

Reducing Judging Time by 80–90%, Enhancing Transparency and Quality

Using Dropbox Replay in judging transformed the previous cumbersome process, where 5–9 judges individually emailed scores and feedback to DMC.

Previously, collecting feedback from judges took up to four weeks; after adopting Dropbox Replay, it was reduced to as little as three days—cutting judging time by 80–90%. Timestamped comments directly on videos eliminated the need to clarify which part of a video a comment referred to.

Manaoat particularly values the ability for judges to view and discuss each other's comments. "Evaluating creative content inevitably involves subjectivity. The ability for judges to discuss these evaluations adds tremendous value. The old method was one-way, with no visibility into who said what. Now, judges can see each other's comments and discuss differing perspectives in real time. With the Live Review feature, they can even debate while watching the video together. This has greatly enhanced transparency in judging." He emphasized that the benefits extend beyond time savings to fairer, more rigorous evaluations.

Features such as labeling video review statuses and consistent playback quality across devices—including smartphones and desktop PCs—further support smooth operations for judges worldwide.

Moreover, comments left by judges on Dropbox Replay can be transferred to tools like Dropbox Paper, enabling organizers to deliver 'raw feedback' directly to participants. Faster, more transparent judging through Dropbox Replay benefits entrants as well. "Participants want not just results, but the reasons behind them, as quickly as possible," said Manaoat. "Judges assign scores, but the qualitative reasoning is captured in their comments. Sharing this with participants is crucial."

Judges are past DMC champions, and receiving feedback from them transforms the competition into more than just a contest—it becomes a 'learning experience.'

New Forms of DJ Learning Enabled by Dropbox

Today, Dropbox is central to DMC's Wildcard judging and broader collaboration, used for archiving competition data, sharing files, creating and co-editing documents in Dropbox Paper, and managing contracts via Dropbox Sign.

Looking ahead, Manaoat envisions expanding this to skill development: "With Dropbox Replay, multiple people can collaborate on the same data. We could create experiential learning opportunities, like workshops or camps, to help DJs improve."

On the growing relationship between generative AI and DJ performance, he emphasized: "In DJing and turntablism, you can't truly delight an audience without authenticity. Only authenticity moves hearts. Track selection and sequencing depend on reading the room and making real-time decisions—something AI cannot replicate. This is where a DJ's unique sensibility is essential."

To aspiring DJs aiming for the world stage, Manaoat shared his passion: "Stay true to your originality and musicality. Don't just follow trends—think about who you are, and express your identity and background. Surprise and excite us. Now and in the future, we will continue running the Wildcard category with the belief that every DJ around the world deserves a fair chance."

Dropbox will continue supporting creative collaboration across diverse fields. We offer consultation services for those considering adoption. For details, please visit:
