The actual use of HUD is really a documentation-free endeavor. However, if you want to pick up some of the finer points of using the HUD, the .pdf documentation is brief, excellent and there are some online videos available for even easier learning. The one area that is worth reading up on is how to create your own artwork for inclusion into the HUD Binocular capabilities.
My biggest surprise was the depth of options (and options within options) that are neatly hidden from the user until enabled. This is yet another area where HUD shines brightly. For example, in the Binocular core setting, in addition to the wide array of video and camera effects at your fingertips, users can also overlay and animate their own imagery. All you could want and more.
Essentially, all of the iconography, data-points, registration marks are appropriately available for the core option selected. The OSD core lets you select from histograms, battery low, variable interference, different reticules and more. It’s like taking the OSD from multiple camcorders and putting them all at your finger tips for you to choose from.
Time markers and data associated metrics are just a click away in the film modes and actually track time. They can also be set to unique starting times of your choice and then progress in real-time.
Text is as flexible as the fonts you have in your system. Size, placement, color and blending are all controllable.
