10 Tips Every Roto Artist Should Know - Silhouette FX Rotoscopy Masterclass - EP 06 [HINDI]

In this 6th Episode of Rotoscopy Masterclass I am going to tell you guys about 10 Tips Every Roto Artist Should Know.Rotoscoping or “Roto” for short has become a generic term for drawing shapes to extract, isolate or affect a portion of an image. It is tedious work, but it’s one of the most important parts of the visual effects process. Within the Roto node, there are all the tools needed to make quick work of any Roto job. Creating usable shape animations can be a bit tricky with the most common problem being edge chatter. Here’s a few tips to help you on your way.
Analyze the Sequence View your sequence to determine the frame that requires the greatest number of points to create the shape. It is easier to draw your shape on the most
complex frame as opposed to starting on a simpler frame and adding points later. Select a Spline Type In Silhouette, you can create B-Splines (also known as natural splines), XSplines, Bézier splines, Circles and Squares. Create Shapes with Less Points Use as many points as needed to create the shape, but avoid using more than is necessary. The fewer the points, the easier it is to successfully animate the shape. Unnecessary shape complexity inevitably leads to inconsistency when editing points.Create Multiple Shapes Create multiple shapes to Roto complex objects. Drawing separate shapes for the major parts of an object give you finer control over motion especially when separate objects intersect with each other. Edit the Shape in Groups
Try not to individually move points in a shape unless absolutely necessary. Moving points in groups will maintain consistency and eliminate edge chatter. Use the Tracker Use the tracker to analyze the motion of your sequence and then apply that motion to your shapes. This will cut down on the number of keyframes needed.Keyframe, Keyframe, Keyframe By editing your shape at various frames in the sequence, Silhouette animates the shape in between those keyframes. This saves you work. Make as few keyframes as possible, but as many as needed so the shape properly follows the object that you are rotoing. For instance, on a 80 frame clip, start by adding
keyframes at 1, 20 and 40. If more animation is needed, add keyframes at 10 and 30. Get the idea? Creating too many keyframes will cause the shape to jitter or chatter.
