--- just a side note, I didn't make these paths, I just collected them, wasn't sure if they will stay on imgur forever ---

Since my video of the waves crashing into the shore was #1 in the video section for a while I got a lot of questions how I made it, so I thought it's easier to make an article. At first I used the amazing ipiv's Morph workflow and set it to bypass the last 3 images and I used a blank path in de Load Video (Path) node.

For the swirling milkshake video I used the Swirl path
