roto scoping

what is roto-scoping ?  roto-scoping is a technique that you can use to animate moving objects or life by getting video footage and drawing over it in the same way as a frame by frame but with the object it is commonly used when they can't draw the movement in frame by frames

you start to roto-scope by getting a video and import it into flash

then you draw over the video in a new layer 

then you delete the video

                                                             lastly to finish by adding colour

The advantages to rotoscoping are that movements are accurate and the image it self should have the correct size the entire time unless you change the brush size like I did and found out that it makes the quality decrease

The disadvantages:  rotoscoping takes a long time to produce the animation and it is mainly used to complete short clips that can't be done with out it because of the amount of time it takes and how tedious it is to animate with

overall opinion : My opinion I think it would be a bad idea to use a rotoscope for the final game trailer because it will take to long and miss the deadline but if there is enough time then it would turn out for a good 2-D animation of a game trailer
