Yay! (OK, I need to work harder to make a better mask). With (iii) and (iv), you will get the image at the start of this tutorial. You can also place text on the first layer outside the masked area. With a mask, you can reduce the keypoints, see (iv), by carefully placing some at the edge of the selection. See the notes below if you are exporting it to other formats when you have masked layers. Layer_selection_mask_all_except_first, menu="/Layer")Īnyway, make sure the Playback and Export settings are set at ‘ Cumulative layers (combine)’ and not at ‘ One frame per layer (replace)’ for the masked layers to work.

The Paths layer can be drag-copied to another image in case you want to re-use it. I used Paths (then ‘ Paths to Selection’ to create (iii).

Working on transparent layers in Morph will produce strange edge artefacts, so you have to work with a full image.Īfter getting your new image, start by creating a selection for where you want to the movement to be. You have to do it after generating the new image, because having a selection before going into G’MIC will crop the image instead. If you export it, there might still be some movement, because it is quite difficult to place the fixed keypoints. See (ii) where there are lot of fixed keypoints. Not only must you put it on the edge of the moving area, but you might have to place quite a few beyond it. This time try to place fixed keypoints for parts of the image which should not move. Go back to your original 2 layers, and open the Morph interface again. Also, since layer #0 and #15 are the same, it looks like there is a pause, which we can eliminate by deleting layer #15, which I will do for other animations. So everything is moving (except the fixed corners). This is how it looks as an animated GIF with the default export settings of 100ms delay between frames (see notes below for other formats):Ġ3 base 16 frames animated 800×600 4.91 MB Open Filters->Animation->Playback to see how the morph turned out. Don’t cross the streams! See (i) in keypoint image at the end below.Īfter you’ve placed the keypoints, press Esc or Q for G’MIC to work on it, and you will have 16 layers (named Morphing #0 to #15) in your new image. For the keypoints, try not to make large displacements, in fact a few small ones are sometimes enough. Please familiarize yourself with it (perhaps morph some faces beforehand) as I won’t go into the details. Here I kept it at 16 frames, but for ‘ Output mode’, I changed it to ‘ New image’, to avoid replacing the original layers. Then open Filters->G’MIC-QT.Ĭhoose Deformations->Morph. Duplicate the layer because you will be morphing the image into itself. Scale it to your preference (and your system capabilities). For this example, I am using ‘ Cachoeira do Pacheco Venezuela 4.JPG’ from Wikimedia Commons. Let’s see how you can do it in Open Source Software. It’s sometimes called a plotagraph (you need a freemium app for that) and it works on a single image, instead of a cinegraph which is from a short movie. I just want to share how I did the above effect in G’MIC & GIMP. 10 less fixed kp masked animated 800×600 2.73 MB
