1 Master mocha Vol. 1 Production Effects with mocha Pro & After Effects Presented by Ben Brownlee

2 Exercise 1 - Blended Approach to Clean-up Overall Project: Clean up the middle ground in the shot to remove distracting features. Take care as the background and foreground elements are in motion. Part 1 (17:17 min) Starting project & identifying the problems. Difficult tracks. Techniques for checking track accuracy. Creating the first mask shapes. Part 2 (17:48 min) Organic shape tracking and creating a hold-in mask. Different ways of bringing Matte shapes into After Effects. The importance of motion blur with matte shapes. Creating a clean plate. Potential problems with background objects. Part 3 (13:50 min) Choosing the correct type of tracking data for the cleanplate. Working with the Align Surface. Grain management part 1. Selling the effect with environmental effects. Re-using the tracking data for matchmoves.

3 Overall Project: Extend a location using a matte painting. The camera movement is a tilt upwards and must be smoothed to remove the bounciness. Part 0 - Introduction (2:06 min) Seeing the scope of the exercise. Doubling the height of a factory. Removing a distracting sign. Minimizing the bounce in the camera move. Part 1 (11:54 min) Finding a good place to track for stabilization. Working in the Stabilize Module. Smoothing vs. Stabilization. Improving a camera move with the Frame List. Taking out Stabilization data to After Effects. Removing stabilization borders - method 1. Part 2 (20:46 min) mocha s Stabilize Module pt2. Removing stabilization borders - method 2. mocha s AutoFill to create stabilization without scaling. Creating the best type of tracking and shape data for AutoFill. Solving potential problems with AutoFill results. Part 3 (22:27 min) Exercise 2 - Set Extensions Matte Painting in Photoshop for the set extension. Different techniques to extend buildings. Removing objects in perspective on a single frame.

4 Exercise 2 - Set Extensions Overall Project: Extend a location using a matte painting. The camera movement is a tilt upwards and must be smoothed to remove the bounciness. Part 4 (24:42 min) Adding the matte painting to the original footage. Matchmoving the matte painting. Problems with nodal camera moves and simple motion tracking. Minimizing the bounce in the camera move. Fixing the track. Integrating the set extension. Tracking for the sign removal. Integrating the new elements - color correction. Adding environment effects. Smart use of mocha tracks. Part 5 (13:26 min) Cleaning up the sign removal. Quick ways of cleaning background areas. More grain management. Finishing the effect.

5 Exercise 3 - Advanced Remove Overall Project: Remove a large object that is traveling through the shot. Be aware that the object covers many different planes and background areas. A 3D camera solve is also required. Part 0 - Introduction (2:56 min) See the before/after for the cleanup. Removing a sign that obscures a large area of the screen with a moving camera. Create a 3D tracked camera to add environmental and text effects. Checking out the different stages required in this clean-up. Part 1 (29:27 min) Tracking the ground plane on a trucking camera shot. Identifying the different planes we will need to track for our first remove stage. Adding track mattes for tracking and remove. Testing the tracks. Fixing inaccurate tracks with AdjustTrack. When to fix and when to trash your work. Unlink tracking - to track tough camera moves. Final preparations for the Remove Module. Part 2 (24:02 min) Working with the Remove Module. Simple set-ups for Remove. Testing the settings and improving results. Compensating for objects and areas moving in perspective. Reducing artefacting and problems with render. Balancing render speed and quality.

6 Part 3 (11:56 min) Exercise 3 - Advanced Remove Reviewing the results from the first round of mocha Pro Remove. Offsetting track data to create accurate Surface data for Corner Pin. Export the correct corner pin data type for our Stabilize/Destabilize workflow. Part 4 (15:54 min) Using the Stabilize/Destabilize workflow in After Effects to fix problem areas. Working with other corner pin plug-in filters. Speeding the workflow with mochaimport+. Quickly identify and repair complex problems in our Remove work-in-progress, with simple masks and offsets. Part 5 (13:37 min) Sky replacements. Improving the source image in mocha before tracking. Creating a quick hold-in mask from existing track data. How to import the data into After Effects to create a fast and accurate sky replacement. Fixing shape layers in mocha. Final tweaks for the effect in After Effects. Balancing render speed and quality.

7 Part 6 (25:54 min) Exercise 3 - Advanced Remove Remove Round 2. Refining our track areas to create a more accurate result in the Remove Module. Offsetting our wall track to another area of the footage. Tweaking the data with AdjustTrack. See a new tracking technique to track the underside of the bridge. Set up layer order for Remove Round 2. How to use the Merge Projects feature to re-use elements from other projects. Compare the results of doing Remove in two passes versus one pass. Part 7 (17:17 min) Filling in the bridge area. Review of Remove Round 2. More stabilization/destabilization to fix artefacts. Review the improvements made between the three work-in-progress. Paint and cloning to fix stubborn areas. Using and mixing multiple masks to fix different sections. Feather complex effects with adjustment layers.

8 Part 8 (29:54 min) Exercise 3 - Advanced Remove 3D Camera Solve. Identifying suitable planes to track. Check, fix and cull shape tracks. mocha s Camera Solve module. Improving Solve Quality. Export camera data into After Effects. Checking the data and Camera Solve. Offsetting data for untrackable areas. Tidying up our ground plane patch. Part 9 (27:12 min) Finishing the shot. Recycling shape data again. Exporting multiple mask shapes. Quick Poke and Slip techniques. Filling in the details. Review of techniques used to polish the shot. Limiting the range of pre-composed footage to avoid nasty surprises in the final composition. Dealing with softness caused by the Stabilize/Destabilize workflow. Taking out our data again in a different format. Final elements including color grade and 3D text. Final review.

9 Exercise 4 - Advanced Insert Overall Project: Add a new image to two pages of paper. Be careful of the motion and shape of the paper in the wind. Also take care as the pages cross each other on two occaisions. Part 1 (36:30 min) Setting up the shot. The importance of track order. Creating partial tracks to drive track mattes. Working effectively with the Überkey. Issues and workarounds when tracking a completely obscured shape. AdjustTrack with offset reference points. Part 2 (8:44 min) Refining the page masks. Problems with maintaining edge consistency. Finishing the page mask rotoscoping. Part 3 (22:16 min) Taking out the tracking data. Linking and expanding the corner pin tracks. Removing tracking markers. Why the type of corner pin makes a huge difference to the other effects used. Comparing the different corner pin types. Filter layer order. Exporting shape data. Applying mocha masks at the appropriate point in the filter order. More motion blur to masks.

10 Part 4 (17:12 min) Part 5 (21:36min) Exercise 4 - Advanced Insert Rotoscoping shadows to add realism. Save time by using current tracks. Speed and improve accuracy of roto work using the Transform Tool. Exporting shape data for shadows. Create realistic shadows. Work with multiple mask shapes, blend modes and layer order. Complex shape combinations with new and old shapes. Adding in the page inserts. Smart use of mattes. Distorting a flat insert Surface to fit non-planar objects. Revisiting filter layer order and corner pin types. Removing flickering movement on the paper. Composition motion blur settings to match the main footage. Grain management only on the insert.
