Systems, methods, devices, media, and instructions are described for fast video sensor adjustment. In one embodiment, a portable electronic device with image capturing capabilities automatically captures a first plurality of frames upon selection of an input button while sensors of the device are determining camera settings for the environment. The first plurality of frames are captured using different automatic bracketing settings. Once the camera settings are determined, a second plurality of images are captured using the determined camera settings. One or more of the first plurality of images are used along with the second plurality of images for a video file. The one or more images may be selected based on a match between certain of the automatic bracketing settings and the final camera settings. A server computer may then aggregate settings from different devices to provide updated automatic bracketing settings to various devices.
