The Time Bar

The Time Bar is simply a display of a time range. It does not limit or control the actual parameters saved into the script. To set the frame range you want to render, go to the Globals tab and enter the timeRange parameter.

To set the current time, you can either click or drag the time slider, or enter it numerically in the Current frame textfield. As with any textfield, you can use the virtual sliders - Hold Ctrl+drag left button left and right in the textfield.

Middle button or Alt+Left button both will pan the Time Bar.

Ctrl+Middle button or Ctrl+Alt+Left button will scale the Time Bar.

These controls will start to play through the script according to the Time Bar frame range, not the global timeRange. To make these the same, hit Home on the Time Bar (or on the keyboard), and the Time Bar will take the timeRange as its limits. Doing so will cache your images.

To stop the playback, hit anywhere. There is no fps control for the Time Bar playback. If you Shift-click on a playback button, it will render all frames and store them in the memory. The second time you playback will be much faster.

The key buttons are for jumping to the previous or next keys.

To work with fields, use a .5 for your frame increment.

You also have the following additional keyboard shortcuts:

Functions
left arrow/right arrow retreat/advance a frame based on the Frame increment setting (works in any window)
up arrow/down arrow Jump to next/previous keyframe.
Home Fit the current time range into the Time Bar.
T Toggle timecode/frame display
