Panorama Collage™ Configurations

You can create Collage arrays in any configuration up to 8 x 8 cells. The native aspect ratio of one 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 pixel count close to 800,000 make sure it 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.
