A standard set of transport controls are provided in the toolbar for full playback control:
As with most functions within PFClean, these controls have corresponding keyboard shortcuts, and in many cases extended functionality is only available via the shortcuts. You should check the General section of the Keyboard and Mouse Preferences chapter of this manual for a full list of available playback controls.
The various buttons and fields within this set of controls are:
Displays the current frame number or current timecode, depending on the mode. You can type in a specific frame number or timecode to jump to that frame. An asterix indicates the lower field when de-interlacing is set to "Fields, Upper first" and the upper field de-interlacing is set to "Fields, Lower first".
Marks the current frame as the playback "in" point.
Moves the current frame to the first frame of the clip.
Moves the current frame to the start of the previous edit (only applicable if the Cinema is displaying a sequence of clips).
Moves the current frame back by the number of frames set in the "Step" control.
Moves the current frame forward by the number of frames set in the "Step" controls.
Moves the current frame to the start of the next edit (only applicable if the Cinema is displaying a sequence of clips).
Moves the current frame to the last frame of the clip.
Marks the current frame as the playback "out" point.
Sets the number of frames playback and stepping is incremented by. For example, setting this to 1, its default value, will display every frame; setting it to 2 will display every-other frame etc.
The FPS entry box allows you to enter a target frame rate for playback. Changing this field does not effect the frame rate defined for the clip or the frame rate used elsewhere in the application. Optionally, feedback about the actual frame rate that is being achieved can be displayed by ticking the Actual frame rate entry of the Customize interface item in the Options pulldown menu. If enabled this control shows the playback frame rate that is being achieved along with a colour-coded traffic-light which indicates green if the target frame rate is being met; yellow if the target frame rate is nearly being met (frames are delayed by less than 3 vertical retraces); and red or unlit otherwise. This information is updated every couple of seconds.
All of the transport controls described here are bounded by the In and Out playback points (which are separate to the in/out values for effects or other processing). Unless otherwise set, the In and Out points are the start and end frames of the clip. To move outside of the In and Out points use the Scrub Bar which is described next.
