Incorporating Symmetry into a Temporal…

Today’s post continues the discussion I started yesterday about a moving symmetry effect based on temporal processing of a dancers motion. Yesterday’s post detailed the specifics of how I built a simple MSG preset to create the symmetry effect. Today’s post will take a look at the rest of the processing used to create the overall effect. The 2 images above are frame captures from some processed video.

The paint action sequence (PASeq) shown below was used to create the video processing effects shown above.

The first action step uses the Temporal Difference Matte processing effect (2nd gallery image above). Temporal Image Processing operation mode effects work by taking in multiple frames (at different frame times) from a source movie, and then generating an effects based on processing the multiple frames. As can be seen in the images above, the temporal difference matte can be used to visualize motion taking place over time in a single image. This can be a useful effect for generating a single output image, or for processing an entire video sequence (which was the goal for this particular processing example).

The second action step used the MSG preset we discussed in yesterday;s post, which creates a symmetry effect. The only difference can be seen in the 3rd gallery image above, where the effect was configured to process the current layer as opposed to the source image.

The last 3 Blur action steps are actually sharpening operations. As can be seen in the 4th gallery image above, i’m using an Edge 1 option for the Composite parameter in the Blur image operation to turn it into a multi-reolution sharpening effect. I used different Blur Amount settings for those last 3 action steps (70,70,99) to sharpen different spatial frequency ranges. The 70 and 80 Blur Amount values act as edge sharpeners. The 99 Blur Amount value acts like a contrast boost.

Once I built my processing PASeq, I then ran the Action : Process with Paint Action Sequence : Source to Movie menu command. I could use this menu command since I was working with a loaded source movie file or a woman dancing. A small segment of the completed video processing effect can be seen here.
