Panorama Collage™ Configurations
You can create Collage arrays in any configuration up to 8 x 8 cells. The native aspect ratio of
one DL.3, DL.2 or Axon media server output is 4:3. Some of the arrays configured in
conjunction with the collage generator will output a different overall aspect ratio.
Computing Collage Specifications
The formula to determine the correct size for your collage footage is fairly simple. The native
aspect of HES media servers is 1024 x 768. You can use these numbers to determine the
correct size and aspect ratio for all collage configurations. The total pixel count once
adjustments are made should be close to but not exceed 800,000 pixels total.
Example
To determine and create 8 x 2 collage footage:
1. Open a new composition in a video-editing program such as Adobe After Effects (many
other programs will work).
2. Multiply 8 x 1024 = 8192 (horizontal/width) enter 8192 into the Width column of you
composition setting window
3. Multiply 2 x 768 = 1536 (vertical/height) enter 1536 into the Height column.
The correct
aspect ratio will
appear next to
these numbers,
lock the aspect
ratio button. In
this case it is
16:3.
4. Adjust the Height
with the Aspect
ratio locked then
multiply the
Height and Width
and make
adjustments to the Width until your pixel count is close to 800,000 total.
5. Once you have achieved a pi xel count close to 800,000 make sure i t is a multiple of 16 (for
correct MPEG encoding) by simply dividing your width by 16 and making adjustments.
6. The image shows the resulting configuration determined for a 8 x 2 array.
7. Add your HD footage, size, scale and or crop accordingly, light optimize and out-put your
master file for encoding.
