The various edit operations operate on either a single frame or a continuous range of frames. For example, Add text will add a text box to a single frame and merge frames combines a range of frames into one.
At any time there is one current frame. This is marked in red on the Frame bar and its image is shown in the movie area below.
How to select a single frame:
Selecting single frames is simple – just click with the left mouse button on the Frame bar to display a frame in the movie area and highlight it in red on the Frame bar.
How to select a range of frames:
Selecting a range of frames is still simple, but requires use of the mouse and keyboard together. Select the frame that will form the start or end of the range. Then hold down the Shift key and click on a different frame. You have defined the start and end of a range of frames, and BB FlashBack shows this range by drawing these frames in a different colour.
How to move the start or end of a range:
Keeping the Shift key pressed down, click on a frame in the Frame bar again. If the frame you clicked is nearer the start of the range than the end, BB FlashBack will now make the range start at that frame. Conversely, if the frame you clicked is nearer to the end of the range, BB FlashBack will now make the range end at that frame.
By keeping the Shift key pressed down and clicking on the Frame bar, you can change the start and end frames of the range.
How to quickly view the start and end frames of a range:
By holding down the Ctrl key and pressing the left and right arrow keys, the current frame will switch between the start and end of the range. As usual, the current frame is highlighted in red on the frame bar and shown in the movie area.
This can be useful when merging a range of frames for example, to make sure that the range starts and ends at exactly the right points.
