AE Roto秘诀 FXPHD RTO210-Secrets of Paint and Roto在AE中画遮罩，跟踪，添加或者移除多余的物体，包括岸边房屋的剔除，房间中楼梯的增加，绳索的剔除，直升机威压的擦除等，个人强烈推荐的一个教程，看过真是受益匪浅！课时目录：Class 1: We’ll get an overview of the kinds of paint shots that often come up in a production situation.

Many of the shots we look at in this class we will come back to in detail later in the course.

We’ll start looking into approaches and how to think about removing unwanted elements in the frame.

Class 2: Stairs Another crew member gets in the way.

We’ll go about removing him by replacing the entire half of the frame.

We’ll look at creating the patch in photoshop as well as simple tracking in after effects with hand tweaks using null parents.

Also, we’ll look into a method I call ‘reverse tracking’.

Class 3: Baloons This time we’re going to look at using track mattes in After Effects to single out objects in the frame we can use to block or hide unwanted elements in the shot.

We’ll also get an intro in Mocha AE for tracking and using its data inside of After Effects.

Class 4: Helicopter Using RED footage shot by fxphd, we’ll look at a simple method for removing rigging cables supporting a model helicopter until its explosive demise.

Specifically we’ll show how simple roto shapes, still frames, and color keys can get the job done.

Class 5: Mic Wire Sometimes you can get away with using blurs and different blending filters inside of after effects to remove unwanted elements.

In this case, a mic wire is taped across a guy’s bare chest and we’ll wipe it away with a few filters.

We’ll also use this opportunity to go into a little detail on how I like to approach the specific task of roto.

Class 6: Go Kart Part 1 of 2 We’ll start upping the ante with a fairly difficult shot of another crew member walking straight through the middle of the scene.

We’ll look into some serious tracking with a zoom and handheld camera using pfTrack.

Class 7: Go Kart Part 2 of 2 We’ll finish out the shot by exporting the track into a 3D app to generate a full background using the patch we created in the previous class.

We’ll also look into the roto involved in completing the shot.

Class 8: Shoreline A & B We’ll take a look at a collection of shots that are “the same but different”.

Each shot needs us to remove objects off in the distance, but we’ll take different approaches with each one to illustrate some of the choices you can make when tackling shots.

Class 9: Shoreline C In this class, we’ll take a fast-moving handheld shot out on the ocean and clean the distant shoreline of any distracting buildings, ships, or evidence of civilization.

We’ll look at stitching several stills from different times in the frame into one giant patch.

We’ll track it into the shot, and then briefly look at the roto involved with finishing the shot.

Class 10: Grass canons In the last shot of the course, we’ll remove an entire crew on a grassy hillside.

We’ll look into 3D tracking and ways to rebuild elements of the grassy hillside in 3D and merge them back into the shot.
