Today’s post continues our discussion from yesterday, where we used a source movie taken with a non moving camera that contains objects (pedestrians) moving within the static view scene. Yesterday we worked with the Temporal Scan Tracker to build SlitScan effects. Today we will look at some other temporal image processing effects that work well with static camera view source movies.
We’re still using the same source movie we used for yesterday’s post for today’s examples. It was taken out of the window of a car stopped at a traffic light. The camera does not move (except for some slight camera shake since it was hand held), and a series of pedestrians move within the view in 2 different directions over time.
Yesterday we shows how to configure a slit scan effect so that the movement of the slitscan aperture over time worked well to accent the pedestrian movement in a visually interesting way. Today we will focus on 3 different temporal image processing effects that work with motion in a movie in different ways. The first gallery image above was created with the Temporal Difference Matte effect. The second gallery image above was created with the Temporal Difference1 effect. The last 3 images in the gallery above were created using the Temporal Rank Filter effect.
All of these effects have different editable parameters that can be used to dramatically change the appearance of the resulting time based effect. This should be clear with the 3 examples shown for the Temporal RankFilter above. The 3rd, 4th, and 5th examples above were generated using the Median, Min + Max, and Median Max Distance settings for the Algorithm parameter in the Temporal RankFilter.
The Editor control panel for the first 3 effected gallery images above are shown in the gallery below. The last 2 effected images above use the same Editor parameter settings as the 3rd gallery image below, except that the Algorithm parameter was set to Min + Max, and Median Max Distance settings respectively as opposed to the Median setting shown below.
