The Matte Assist tool relies heavily on your GPU for ML inference. Insufficient dedicated video memory (VRAM) or improper hardware configuration is the most frequent cause of render failures.
🔴 Not all graphics cards are created equal. Even if you have a modern card, it may not meet the specific architecture requirements.
Ensure that the frame rate of the composition matches the native frame rate of the clip exactly. Fractional frame rate mismatches (e.g., 23.976fps vs 24fps) can cause the ML engine to search for nonexistent frames, triggering a render failure. 4. Layer and Matte Organization

Matte Assist ML models are trained primarily on progressive frames. Interlaced footage (1080i) can cause the network to fail during render computation. De-interlace your footage prior to tracking.
Matte Assist relies on deep learning models that load entirely into your graphics card's VRAM. High-resolution footage (4K, 6K, or anamorphic plates) combined with heavy temporal processing can easily exceed hardware thresholds.
: Rendering, especially with ML, requires significant computational power. Insufficient resources (like GPU power, RAM, etc.) can lead to failures. The Matte Assist tool relies heavily on your
If it is set to your GPU (e.g., NVIDIA CUDA or AMD OpenCL), switch it to or OpenVINO (CPU) . Restart Mocha Pro and attempt the render.
Matte Assist ML requires a massive amount of VRAM to process high-resolution frames. If your GPU has less than 8GB of VRAM, 4K or 6K footage can cause an instant render failure.
: This is a feature often used in visual effects and video editing software to help create mattes or masks for objects within a video sequence. It's particularly useful for tasks like chroma keying, object removal, and other tasks requiring a clean separation of subjects from the background. Even if you have a modern card, it
If you've tried all these steps and are still encountering issues, your next port of call should be the official Boris FX Support Portal and the Boris FX User Forums . When you post your issue, always remember to , which can be found under the Help menu. This log file contains invaluable information that will allow support staff to quickly diagnose the exact cause of the problem on your machine.
When Mocha Pro throws an ML render failure specifically tied to Matte Assist, the breakdown usually occurs in one of three areas:
Ensure you are running Studio drivers (for NVIDIA) rather than Game Ready drivers. Studio drivers provide optimized stability for enterprise VFX software like Boris FX. 2. Mocha Pro Preference Optimizations
Forcing Mocha Pro to rethink how it uses your hardware can clear initialization bugs. Open the Mocha Pro interface. Navigate to . Locate the GPU Acceleration settings.
The "Matte Assist ML Render Failure" error in Mocha Pro is a common hurdle, but understanding it is the first step to overcoming it. The vast majority of cases are rooted in hardware limitations, specifically .
