What's the best approach to remove a curly object over time (20 seconds). Think of a piece of wrought iron work that should gradually disappear from one end. Do I need to make dozens of masks or is there an easier way? If it helps I own Hitfilm 3 but I've never used it. Thanks.
The best method for removal depends on how the object is placed in the scene. If it is on a separate track and not within the main scene/background, then the "route" method mentioned by Grazie is the way to go. However, if it is part of the scene, then you have to first create a "clean plate" using object removal software (Mocha Pro is by far the best tool for this). Once created, the clean plate would be your background track while the original track would be above that. Then you could use a combination of garbage masks and the route method to accomplish your final effect.
Thanks, Gracie. Did a search for route and came up empty except for stuff about using mapping software which doesn't strike me as relevant. I seem to remember seeing a tutorial about drawing a line but couldn't find it. Also removing a line seems quite different in my tests.
