The brief
A consumer technology company was launching a new flagship product with a keynote in Shenzhen. The audience was deliberately split: tech media and consumers in China watching on domestic platforms, and international press, partners and customers watching overseas. The client wanted one production — not a domestic stream with an international afterthought — with product names, spec callouts and speaker titles rendered correctly in both English and Chinese, live, as each segment happened.
What we did
We built the keynote as a broadcast: four cameras covering the stage wide, the presenter tight, a product close-up position and a floating camera for demo moments, all switched live by our technical director against the run of show.
The bilingual graphics layer was the centerpiece. Working from the client's launch deck and spec sheets, we prepared every lower-third, product callout and transition card in matched English and Chinese versions before show day, then triggered them in real time — the English feed carried English graphics, the domestic feed carried Chinese, from the same switched program. A dedicated graphics operator followed the script alongside the TD so callouts landed on the demo, not after it.
Two stream engineers ran the simulcast: redundant encoders pushing to the client's domestic platforms and to their international destinations at the same time, with bonded 4G/5G backup alongside the venue line. We rehearsed the full keynote, including every graphics cue and a stream test to each platform, the day before launch.
The result
Launch day ran to the second. Both sides of the simulcast went live together and stayed up for the full keynote, and the client's team — briefing us in English while we ran the venue in Chinese — worked through a single technical producer rather than coordinating two separate streaming vendors. They walked away with program and ISO recordings plus a clean feed for their own regional re-edits, and a launch film that looked the same whether you watched it in Shenzhen or San Francisco.
