You're watching VisiHow. In this video, I'm going to show you how you can apply a trace contour to a video clip in Photoshop CS6 in Windows 7. As you can see, I've already opened Photoshop CS6, and I've imported my video. We have a preview in the middle, the timeline at the bottom, and the layer on the right-hand side. Make sure you've selected the layer you want to work with and converted it to a smart object. This is something you should do before you add any filters to video because otherwise, Photoshop will apply it on a frame-by-frame basis. The smart object basically makes the whole video clip one frame, so you're restricted with some things, but you can add filters as if it's an image. If you need to find out how to do that, then refer to our tutorial on how to convert a layer into a smart object in Photoshop CS6.
It is also being previewed on the canvas. We can generally see what the filter is trying to do. Trace contour basically follows contour lines within the video or the image, and traces along those in different colors.
