AClapBoard. 1.4

A digital clapboard / Slate and client time measurement system.

New features: map display, timecode calculator, 2-pop sync, color charts.

The application combines two function, first its a handy time measurement for spending times at work processes.
The second function is a digital clapboard, which can be used for synchronisation of multiple cameras, e.g. the classic clapboard function, but also for scene management. The IN and OUT times can be recorded, to have an easy overview of scene lengths. The clapboard can display scene numners, takes, pickups, MOS, etc.
Also user selectable is the fps (15..100 fps), displayed in the running timecode, which can be either a realtime clock or a manual set start.
Pressing the start button triggers the sync function after 5 seconds. You can choose between different clap sounds and animations, After the sync has been done, you can start the IN point, for example when the action takes place and after an OUT point, so you know the scene length.
A nice function is the digital nivelling function, so a horizontal position of the clapboard can be used to align the camera (two arrows optional displayed at the side show the alingment).
All is stored to a hierarchical database with project and production names.
The result can be displayed or send via email as plain text, CSV, or html text.
A GET LOCATION button allows you to mark the scene with the actual measured location (iPhone GPS for example).
All scenes can have additional notes stored in the database.

Beside the film projects you can also define task projects, and define a taskname, notes, and trigger an IN and OUT, so you measure programming tasks,or maintenance at clients or for film projects times for cutting, sound effects etc. The list is also saved in the database and can be send via email.
Also a location information can be saved and you simply click on the map link to see where you took the scene or task.

We work since years for tv production (BR ComputerTreff and ComputerTrend.TV) and missed such a handy device, using pen and blocks, or even simply claps for our stereo camcorder projects or separate sound syncing when using a lower cost camcorder (most HDTV consumer products lack in a good audio!).
So it was done also for our own usage.

This is the clapboard before you start it. You can change the scene numbers also directly here. If displayed in red, its already used. The yellow arrows at the side follow the gravitation for horizontal alignment (level option)
