Rotoscoping, animation process for the window enemy in You've Changed

Here is a behind the scenes look at how one of the sequences in the "House" level was rotoscoped frame-by-frame in You've Changed.

Rough guide for rotoscoping process for this sequence:

  • Record video
  • Create new Da Vinci Resolve timeline as 30fps when you create your project
  • Use Da Vinci Resolve stabilization perspective and locked camera mode to stabilize
  • Import 1080p, nearest neighbour scaled-up scene from the game as a reference to help position the camera
  • Move the video into position within the scene
  • It may help to remove the background of the video or crop it
  • Export the video as 320x180 (the game's resolution) with the following settings: Alpha, Png 16 bit, 30 fps
  • If you need to have 15fps animation, use a PowerShell script to delete every other frame. Then I used a script to rename all the files to ascending numbers so Aseprite would be able to import them correctly.
  • Import folder into Aseprite as animation. 33ms duration for 30fps. 67ms duration for 15fps.
  • Use select tool to select area of animation
  • Then use crop tool
  • Then press save and it will export all the pngs again
  • Import your desired color palette, in my case I'm using a NES color palette
  • Create a new layer in Aseprite, draw on that then remove the bottom layer before export
  • Save Aseprite project
