Yes at least their camera division, but they seem to be diversifying / branching out lately.
Just been looking for more SOC info, and the thing is too new.
But found some general info on the H3 SOC and
daummmm 8K or if you want dual 4K/60 steams with EIS it seem
"
The H3 video SoC enables 8K Ultra HD H.264/AVC video at 30 frames per second, as well as multiple video streams with equivalent performance, including dual 4Kp60 sensor video capture.
8K videos played on large 8K displays provide a superior viewing experience to the end user, as pixels at this resolution are indistinguishable to the human eye at any reasonable distance. The combination of 8K video capture together with Ambarella’s advanced oversampling and image stabilization also enables higher video quality 4K video recording.
H3 includes a powerful multi-channel ISP for multi-sensor drone applications. Its 10-bit HEVC High Dynamic Range (HDR) video processing handles high-contrast and wide color range scenes. It also features Ambarella’s advanced Electronic Image Stabilization (EIS), capable of generating a smooth 4Kp60 video output under challenging conditions, including during high winds and with high degrees of rotation. The H3’s hardware de-warping engine supports wide-angle panoramic camera designs and fish-eye lenses."
