Sounds really gay but he's wearing vans and I think nike in those pictures so I doubt it'll be used for the analog video.
Analog is not tied to gravis in the same way etnies clothing is tied to its shoes.
In regards to why film of these photo'd tricks wasn't in mindfield I see a couple options.
-To edit a video part invariably implies that an editing process is taking place.
-Like Mike Taylor, the footage may have been from too long ago when dylan dressed and skated a bit differently. To take out earlier footage is a way to strengthen the more current image.
-It is also possible that for every trick photographed there may not exist an equivalent in video. He strikes me as an Austin Stephens or a Pops type of image maker in that some footage remains only photo footage. To divide the video from the photo in this way suggests a thoughtfulness in a trick's selection in relation its particular form of representation.
