There are a few iPad painting programs that either automatically record your paintings as they are created or that you can set beforehand to record as you paint. Procreate, SketchClub, Sketchbook Pro, are some current paint programs that allow you to create videos of your paintings in process.
In this post I'll talk a little about recording video in the Procreate app. While you are working on any painting in Procreate, Procreate is automatically making a video of your work in progress behind the scene. At any point, you can click on the little wrench (Actions) icon at the top left of the screen, then click on share and then send your video to email, Dropbox, ITunes, or even save it to your iPad Photos.
The video above shows an unfinished Procreate painting in progress. Watching the video, it is interesting and helpful for me to see my process. Sometimes I find a place where there was something I liked but got changed. sometimes I can go back and recreate it.
This painting started out in ArtRage, as do many of my iPad paintings, because I love to capture the oil brush and watercolor brush textures. Then I usually save the image and open it up in Procreate. Most of the ArtRage painting gets covered up, but I like to leave some of the texture.
The progress video shows me adding a second image on top of the first image and then keeping only parts of it. I used some copy and paste and transform in the painting. Near the end of the painting, I accidentally added a big green line across the girl's face when I was pinching out the screen to magnify the area I was working on. You can see me deleting it in the video.
I love using the videos as tools to help me remember my process and to help me remember how I got certain effects.
