Juno's Perijove-17 Jupiter Flyby, Reconstructed in 125-Fold Time-Lapse
The movie is a reconstruction of the 2 hours and 15 minutes between 2018-12-21T16:15:00.000 and 2018-12-21T18:30:00.000 in 125-fold time-lapse. It is based on 30 of the JunoCam images taken, and on spacecraft trajectory data provided via SPICE kernel files. In steps of five real-time seconds, one still images of the movie has been rendered from at least one suitable raw image. This resulted in short scenes, usually of a few seconds. Playing with 25 images per second results in 125-fold time-lapse. Resulting overlapping scenes have been blended using the ffmpeg tool. In natural colors, Jupiter looks pretty pale. Therefore, the still images are approximately illumination-adusted, i.e. almost flattened, and consecutively gamma-stretched to the 4th power of radiometric values, in order to enhance contrast and color.
