The Editor in Stop Motion Pro is pretty much unique. You can see all your frames in a thumbnail view that you can drag and drop, copy, duplicate and reverse. The Editor gives you the power to experiment with timing in a non destructive way, thanks to the concept of "hiding" frames.
This functionality is in all editions of Stop Motion Pro v7. Stop Motion Pro Studio editions have extra frame grouping functions, which are demonstrated in the video below.
How to use the Editor:
Capture some frames in SMP.
Right click on a stored frame and select hide frame or duplicate frame. The delete key on your keyboard will also hide a frame.
The Editor is accessed via the Editor button on the main toolbar.
Hidden frames have a yellow diagonal line through them.
Right click on frames in the Editor to unhide / hide.
Use the Shift and Ctrl keys on your keyboard to select mulitple frames.
Some handy Actions explinations
Reverse order of frames
Select multiple frames, then choose this option to reverse the order, for example if you select frames 1,2,3,4 and choose this option, they are reordered 4,3,2,1
Repeat selected sequence
Copies and pastes an entire sequence, as a sequence. Use the Count spinner to specify the number of times the sequence should be repeated.
Repeat selected frames
Duplicates each frame and pastes it after itself, so you could turn a sequence filmed on "ones" into a sequence filmed on "twos", slowing the animation down. Use the Count spinner to specify the number of frames to be repeated.
Insert blank frames
Inserts black frames. Use the Count spinner to specify the number of blanks.
Copy/paste frame as Bitmap
Copies the frame in a format compatible with other image editing applications (such as Photoshop, Windows Paint etc.
Note:
When you capture or copy/paste a frame in SMP, it is given a unique Frame ID that never changes, even if the frames are reordered in the editor. You can see this number under your frames in the editor by choosing the Editor sidebar tab Settings | Show Frame ID. This means you can always re order your frames in the sequence they were captured.
The video below shows some of the more advanced functions such as grouping - showing how you can experiment with timing.
