The following page describes the Eyesis camera post-processing procedures.

Fig.1 Eyesis frames

3x 500GB HDDs (or 3x 256GB SSD HDDs), each containing *.mov files from 3x 3-sensor cameras (a single HDD is connected to a camera).
Each frame in a *.mov file is a combination of frames from 3 sensors glued vertically.
The cameras are numbered - 1,2,3. The sub images are [1.1, 1.2, 1.3], [2.1, 2.2, 2.3], [3.1, 3.2, 3.3]. 3.1 is the fisheye image.
The frames in *.movs are indexed.
Single frame format is JP4.
Corresponding frames have the same time stamps generated by the 1st camera.
The 1st camera frames are geotagged.

Stitching scripts samples.

JP4 images are extracted and converted to DNGs from *.MOVs by the program movie2dng.

Dcraw and the Hugin tools are used for stitching (a template *.pto for it should be created once).

-* As the frames' index is stored in each corresponding *.mov, it is read and used for building the index of all the frames on 3x drives.
- *.mov header's 'stco'-tag contains offsets for all the frames in the file.
