Frame sync’ing cameras together is one of the main benefits of using digital high speed cameras rather than analogue. The idea of frame locked cameras was unheard of in the days of cine cameras. Until very recently, frame sync’ing wirelessly has just been a pipe dream. Most digital high speed cameras have cables for sync’ing,…
High speed cameras are often synchonised, (aka genlocked, framelocked) together. All but the most basic cameras include the ability to input or output a sync signal for this purpose. Creating movies with frames captured at exactly the same instant has many uses, including: Accurate motion analysis of an event with cameras at multiple viewing positions…
Producing a 3D movie is not as complicated as you might think. There are a few different formats of 3D file that are played on various devices. Here, I’ll explain how to produce a side-by-side movie, which seems to be the most common for playing on a 3D TV. A side by side movie made…
There are many reasons why you’d want to synchronise two or more cameras together including. To analyse a test from different viewpoints, with an accurate timebase. To create 3D movies Multiple cameras share a pulsed light source (LED or laser) In either case, the camera configuration is the same. The cameras need to have ‘sync…
When a set up takes a while to set up and you’re only filming for a fraction of a second, why would you want to use auto-exposure? Well, even in a fraction of a second, the lighting requirements might change quite dramatically. Consider filming an airbag deploying (why are dashboards always black and airbags always…
When two cameras are looking at the same subject from opposite directions, and require different lighting (as one camera would be looking straight at the opposing lights), if camera A and strobing light A are out of sync with camera B and light B, each would only benefit from its own light source, and not…
