step 4

Inserting Frames on either end of the animation

First, make sure you're looking at the first frame. Scrub to the first frame (0) at left on the animation toolbar.

Notice the frame number (0) in the title bar of PD Pro.

Click the plus [+] button near the right of the animation toolbar. It will insert one frame wth the same image. The new frame is inserted in front of the current frame, but you're still looking at the same current frame which is now frame #1, so you are no longer at the first frame. (there are now a total of 91 frames)

Thus, drag the scrollbar to the left once more to ensure that you're on the very first frame. You can also use the Left/Right arrow (cursor) keys on the keyboard.

Notice that the first frame is already containing the first imprint of the blue brush image since the brush stroke started on the first frame.

You will want to have a bunch of frames inserted that don't contain the first brush imprint. Thus, simply click the stored image, which contains the original 'scratch me now' message. Clicking the thumbnail puts that image back into the current buffer, in this case the new frame 0.

Now you can click the "+" button many more times to further insert copies of that same original blank image, without the initial brush imprint.

This is a quick way suitable for just a few frames, perhaps up to a few dozens. If you have many many more frames you want to insert, use the block insertion tools. You can set a marker at one frame, and another at a later frame, all of which have the same original blank image. Then use the frame copying and insertion tools. These tools can be found, amongst other places, in the Animation>Frames... menus.

After inserting the original frames in this manner at the beginning of the animation, scrub to the last frame. That last frame contains the final, total extent of your brush stroke's blue paint. Simply use the Insert frame button again to replicate that frame

If you insert too many, you can use the pirate head button to kill (delete) excess frames.

Another thing you should try is the FPS button - Frames Per Second. You can use it to playback the animation faster or slower.

Play it at 60 fps for example to see.

If you haven't done so yet, this would be a good time to save your animation. The

menu:Animation > Save...

option lets you save a quick memory dump of the frames's RGB channels, in uncompressed form. It's fast but uses lots of disk space, and if you have a slow disk it may actually be faster to save to some avi codec even compressed (but stay away of lossy compressions until you're all done). The above option saves to .dwa format (Dogwaffle Animation). There's a free viewer for standalone playback available for this too.

You could also save to image sequences, such as Targa or BMP. Or, as mentioned, to AVI.
