[TUTORIAL] Preview a map from a video of a game without raw data(2 or 2,5D only)

[iyenal]

Theory :

The principle is simple : a video of a 2D game have in each frame an part of the precedent frame.
Therefore : The frames are continuous.
Conclusion : we can reconstitute the map by assembling frames.

Now moving from theory to practice :

1 - Find a video of exploration of the 2D or 2,5D map (Youtube,capture...) in MP4 (best quality possible!)
2 - Download and install Microsoft Image Composite Editor(copyright to Microsoft)
3 - Import it and set Planar projection and wait.
4 - Fix manually problems with an Image Editor

Example (Affordable Space Adventures Wii U)(from 1080P video) :
As you can see, there are some problems in the map, but it can be fixed manually.

Hoping I could help.
