Hi, This may be a stupid question but i'm new to flash.
I am doing rotoscoping and draw with the brush tool on a new layer over the top of a live action video.
I would like to be able to use the subselection tool on my previously drawn brush lines and move segments of the lines rather than redrawing them for the next frame.
The problem is that with the subselect tool I can only seem to select points either on the inside or outside of the brush line, meaning I can only expand part of the line. I would like to be able to select the matching inside and outside points at the same time and move them together.
Here is an example of how I can only select inside points
A better way would be to draw using strokes (Pencil tool). You may set the desired pencil mode and smoothness as per your need. Once you have drawn, its easy to make the corrections with strokes. Finally if you wish to convert them to brush fills, simply Select all the strokes and goto Modify Menu > Shape > Convert lines to fills.
If you still wish to modify your brush strokes, use sub-selection tool. Select the area you wish to modify (the anchor points present within the selection rectangle get selected.) Now use keyboard arrows to move the selected anchors around in sync with each other.
Hope this helps!
