Here are some screenshots of Folded Space's MFE (Multi-Format-Encoding) in action! Just got authorization to post these. First, here is a screenshot of a test pattern. The image on the left was created by taking a 2560 x 1080 native test pattern, reducing it to 1920 x 810 letterbox, then scaling it back up to 2560 x 1080, using the best scaling algorithms available in professional Blu-ray mastering software. The image on the right was created by using the MFE process, taking the same 2560 x 1080 test pattern, reducing it to 1920 x 810 using MFE, then re-integrating the extra resolution hidden by MFE behind the black letterbox bars to recreate the 2560 x 1080 pattern. To create the side by side, a native 960 x 1080 crop was taken of each result for comparison's sake. On the test pattern, look at V1 and H1 plus the image of the building in particular. Make sure you download and view the images at full 1920 x 1080 resolution to clearly see what is going on.
Now, here is a screengrab of a scene from an actual film, with standard letterboxing on the left, MFE letterboxing on the right. The two sides of the image should be essentially identical, however, I have "unmasked" the MFE process to reveal the extra resolution that would normally be hidden behind the black bars with a Java graphic. Of course, the extra resolution has not been re-integrated yet. so both sides are the same resolution:
Now, here is a side by side of the same image with standard scaling from 1920 x 810 on the left, MFE re-integration of the resolution on the right (using the exact same process as outlined above re: the test pattern):
Here is another side by side screen grab. Check the detail in the grass, wood, tree and signs:
Here is a screen grab of the full anamorphic frame used to create the above image:
Lastly, I have attached the original test pattern file so you can compare to the MFE reconstructed version. This way you can see that we are playing fair and that the MFE process does not introduce any artifacts.
