Better optimization for the speeding up of clips
I think you guys should look into optimization for the speeding up of 4K60 clips. Even with powerhouse machines with top specs over 4x speed up lags badly in playback. Whereas even on an iPad Pro with Luma Fusion or Videoleap, one can speed up clips up to and over 5x with 0 lag, in playback and no issues with the timeline. If this isn't a bug issue, you guys must consider going in an optimizing this.
