The Huawei Mate 30 Pro has been out for a few weeks outside the US, mainly in China and India and we have gathered 15 video samples from its slow motion mode which as of today is the best performing high-speed phone ever developed. We had some shortcomings about the way the phone reaches the highly hyped 7,680fps mode which is 1920fps multiplied by 4x in software from a small snapshot of the video memory.
We also had some suspicions that the 1080p 960fps mode was also interpolated but looking at the samples we gathered it seems that was a premature call. The phone is actually capturing the full frame rate at 1080p or close to that. The real max mode is 1920fps at 720p which is then interpolated to 7,680fps with good success by the new Kirin 990 chipset. Your mileage may vary and the results depend on the subject matter more than anything as organic slower motion looks much better than fast unpredictable bursts that break the interpolation algorithm.
