Gif problem

[Ofnuts]

Using my ofn-interleave-layers script:

1. The GIF image is optimized, so first unoptimize it (Filter > Animation > Unoptimize)
   
2. Crop a 200-pix wide image in that GIF (around the middle seems best). Don't forget to set "Delete cropped pixels" in the Crop tool options
   
3. Set the image to 320 pixels high: Image > Canvas size, with Resize all layers, Fill with transparency. In the preview, drag the image to the bottom (we want the image to be extended at the top)
   
4. Set the image mode to RGB (Image > Mode > RGB)
   
5. If not done already, oOpen the PNG image as another image in Gimp, and go back to the resized animation image
   
6. If you have installed the script above: Image > Interleave layers > Single layer under stack
   • In the Layer choice, you'll find your PNG image (possibly at the bottom, below all the GIF frames)
     
   • Decrease opacity a bit (70% in exmaple)
     
   • Set Mode to Lighten only
     
   • Set Merge to Yes
     
7. Run the script, this will create a new image
   
8. You can use the Filters > Animation > Playback to test it. If you don't like it, discard that image and try other settings using the image from step 4.
   

Result below truncated to the first 25 frames to fit the upload limit. Result isn't that different fro the same with 120 frames.
