Matte Assist Ml Render Failure Mocha Pro Verified
This error typically appears after Mocha Pro has successfully analyzed the clip, trained the ML model on your foreground selection, and seemingly begun the final render pass. Instead of a clean alpha channel, you are met with a gray preview, a black screen, or an abrupt crash notification.
When you re-apply Matte Assist, click "Retrain from Scratch" instead of "Continue Training" to ensure no residual data corrupts the new cache. Solution 3: Sanitize Your Input Clip (Host Application Fixes) The failure often originates before Mocha receives the frame. This is especially true for After Effects and Nuke users. matte assist ml render failure mocha pro verified
For the remaining 1% of cases involving exotic hardware or corrupted OS libraries, Boris FX support offers a diagnostic tool ( MochaProDiagnostic.exe on Windows, MochaProDiagnostic.app on Mac) that captures the exact TensorFlow or PyTorch backend error. This error typically appears after Mocha Pro has
Do not render Matte Assist at full resolution immediately. In the Matte Assist module properties, set "Render Resolution" from Full to Half or Quarter . Once verified, you can render the matte at full resolution using Mocha’s "Export Matte" feature separately. Solution 3: Sanitize Your Input Clip (Host Application
Reduce your render resolution to Half, delete your local ML cache, and retrain on a shorter clip.
Open the Clip tab. Use the Input Trim sliders to isolate only the exact frames where the object is moving. Rendering a 500-frame clip with ML fails far less often than rendering 2,000 frames.
In Mocha Pro’s Preferences > GPU & Performance , uncheck "Allow background ML rendering." This forces the GPU to dedicate all resources to the current task. Solution 2: Reset & Recache the ML Model The ML model used by Matte Assist can become desynchronized.
