Understanding the Tools and Techniques

Introduction to MTracker Surface

MotionVFX's MTracker Surface is a powerful plugin designed for Final Cut Pro, enabling users to perform planar tracking with ease. Planar tracking allows you to track flat surfaces, enabling you to replace screens, remove objects, and integrate visual elements with precision.

Before jumping into the tutorial, it's recommended that you familiarize yourself with MTracker Surface and its functionalities. MotionVFX provides tutorials on their website motionvfx.com, covering basic mesh tracking, planar screen replacement, and skin mesh tracking. These tutorials serve as a great foundation before tackling more advanced tasks.

Adobe Photoshop: The Content Replacement Powerhouse

Adobe Photoshop is essential for crafting seamless content replacements. Its generative fill feature and various selection tools enable you to remove unwanted elements from still frames, while maintaining realistic textures and lighting. The Tutorial leverages Photoshop to refine the results, ensuring a polished and professional look.

Emroto AI: AI-Powered Masking

Emroto AI assists in creating accurate masks in video editing, which can isolate particular parts for effect enhancement. This enables you to separate subjects from their backgrounds, allowing for detailed masking without manually drawing each frame. This AI-driven approach greatly accelerates the compositing process.

Step-by-Step Guide: Object Removal Tutorial

Preparation and Initial Setup

To start, import your video footage into Final Cut Pro.

Begin by importing the necessary footage into Final Cut Pro. For this tutorial, three separate removals are demonstrated:

  1. Removing a sign from a brick wall
  2. Cleaning up a window and brick section
  3. Removing an awning

To streamline the process, make blade cuts around the specific areas needing adjustments. This minimizes the tracking time and enhances efficiency. Use shortcut 'B' and select the point where you want to separate the footage.

Applying MTracker Surface for Sign Removal

Apply the MTracker Surface effect to the first section of the clip. This tool is great because of its ability to track and map planar surfaces within the footage

. With planar mode active, draw a mask around the object to be removed, in this case, the "Loosa" sign on the brick wall. Use the tracker controls to track the surface forward throughout the duration of the selected clip. This ensures that the mask remains aligned with the sign's movement.

Leveraging Photoshop for Seamless Replacement

Once you have tracked the section, it's time to create a clean plate for content replacement.

To do this, export a still frame from your tracked footage at the point where the sign is most visible. Open this frame in Adobe Photoshop. Use Photoshop’s generative fill feature and selection tools to eliminate the sign. This process maintains textures and lighting, making the replacement seamless. Export the cleaned frame as a PNG file.

Importing and Integrating the Clean Plate

Return to Final Cut Pro and import the cleaned PNG file. Place this image above the original video layer, aligning it precisely with the tracked mask. Set Image Insert Mode to “Fullscreen”.

Since MTracker Surface is only happening inside of the mask, there will be a section when you disable “Loosa” that the brick remains. Drag what you removed in Photoshop into the track and link the data to the surface and select all the effects.

Masking the Window and Brick Sections

To remove the sign from window and remove the top of the brick sections using again MTracker Surface.

Select those two areas that you would like to clean in that section. Since the AI tracking is already on that top video track, you won’t need to copy it from the previous one. Using the pencil tool, you can add points above your hat and hand to refine the AI and help make that blend of two parts of the video as smooth as possible. With all that done, select the key framing again to continue that smooth track down to those parts. For the last section it is key to find what frame you made the effect on so that it transitions correctly.

Refining the MTracker with Emroto AI Integration

After all these steps, apply Emroto AI to finalize this clean track for the effect blend. The tool will add new lines to further track what’s going on. Once again, with Mtracker Surface, we find two different sets of tools

. If there are any additional errors, you can use those to help fill them in too.

Removing the Awning and Adding Some Final Touches

After all these steps, apply Emroto AI to finalize this clean track for the effect blend

. To show this feature, we are selecting to use a surface from what’s right behind that awning. If there are any additional errors, you can use those to help fill them in too. Make sure to do some editing with these settings and the key frames, so that you do not come into the frame. Also using blending modes can be an interesting choice depending on the surface selected.
