Huawei executive explains Huawei Mate 30 7,680fps slow-motion video capture

Huawei Mate 30 Pro

The recently released Huawei Mate 30 Pro is definitively a stellar smartphone when it comes to camera performance. Besides everything powerful characteristic of this impressive camera array, there’s a particular feature that is somewhat intriguing – 7,680fps slow-motion video capture. This basically blows away most of the smartphones in the industry that are usually capped at 960fps video. The Mate 30 Pro achieves eight times more what we’re used to see in most flagships.

Gizchina News of the week

Huawei’s Executive Bruce Lee decided to shed some light explaining how the development team of Mate 30 achieved this impressive feat. According to him, the handset records 0.12 seconds of footage, which then expands to 32 seconds of 30fps slow-mo video. This results in 945 frames captured at 720p resolution. The whole process makes use of the entire chipset’s capabilities. That means that ISP, CPU, GPU and NPU are all working to process the data.

However, human reflexes aren’t nearly fast enough to pick the best time to start recording. Instead, the NPU (Neural Processing Unit) analyzes 1 second of video using an AI algorithm to select when to start the 0.12-second clip. That’s a demanding process that consumes up to 2GB of RAM. While this may seem too much, the Huawei Mate 30 Pro boasts 8GB of RAM. And, Huawei just has found a good way to use this astonishing amount other than leaving it for multi-tasking.
