The 16th ACM Multimedia Systems Conference (with the associated workshops: NOSSDAV 2025 and MMVE 2025) was held from March 31st to April 4th 2025, in Stellenbosch, South Africa. By choosing this location, the steering committee marked a milestone for SIGMM: MMSys became the very first SIGMM conference to take place on the African continent. This perfectly aligns with the SIGMM ongoing mission to build an inclusive and globally representative multimedia‑systems community.
The MMSys conference brings together researchers in multimedia systems to showcase and exchange their cutting-edge research findings. Once again, there were technical talks spanning various multimedia domains and inspiring keynote presentations.
Recognising the importance of in‑person exchange—especially for early‑career researchers—SIGMM once again funded Student Travel Grants. This support enabled a group of doctoral students to attend the conference, present their work and start building their international peer networks.
In this column, the recipients of the travel grants share their experiences at MMSys 2025.
Guodong Chen – PhD student, Northeastern University, USA
What an incredible experience attending ACM MMSys 2025 in South Africa! Huge thanks to SIGMM for the travel grant that made this possible.
It was an honour to present our paper, “TVMC: Time-Varying Mesh Compression Using Volume-Tracked Reference Meshes”, and I’m so happy that it received the Best Reproducible Paper Award!
MMSys is not that huge, but it’s truly great. It’s exceptionally well-organized, and what impressed me the most was the openness and enthusiasm of the community. Everyone is eager to communicate, exchange ideas, and dive deep into cutting-edge multimedia systems research. I made many new friends and discovered exciting overlaps between my research and the work of other groups. I believe many collaborations are on the way and that, to me, is the true mark of a successful conference.
Besides the conference, South Africa was amazing, don’t miss the wonderful wines of Stellenbosch and the unforgettable experience of a safari tour.
Lea Brzica – PhD student, University of Zagreb, Croatia
Attending MMSys’25 in Stellenbosch, South Africa was an unforgettable and inspiring experience. As a new PhD student and early-career researcher, this was not only my first in-person conference but also my first time presenting. I was honoured to share my work, “Analysis of User Experience and Task Performance in a Multi-User Cross-Reality Virtual Object Manipulation Task,” and excited to see genuine interest from other attendees.
Beyond the workshop and technical sessions, I thoroughly enjoyed the keynotes and panel discussions. The poster sessions and demos were great opportunities to explore new ideas and engage with people from all over the world.
One of the most meaningful aspects of the conference was the opportunity to meet fellow PhD students and researchers face-to-face. The coffee breaks and social activities created a welcoming atmosphere that made it easy to form new connections.
I am truly grateful to SIGMM for supporting my participation. The travel grant helped alleviate the financial burden of international travel and made this experience possible. I’m already hoping for the chance to come back and be part of it all over again!

My time at MMSys 2025 was an incredibly rewarding experience. It was great meeting so many interesting and passionate people in the field, and the reception was both enthusiastic and exceptionally well organized. I want to sincerely thank SIGMM for the travel grant, as their support made it possible for me to attend and present my work. South Africa was an amazing destination, and the entire experience was both professionally and personally unforgettable. MMSys was also the perfect environment for networking, offering countless opportunities to connect with researchers and industry experts. It was truly exciting to see so much interest in my work and to engage in meaningful conversations with others in the multimedia systems community.
