FrameFixPro
Similar to existing FrameFix tools, but supercharged with a streamlined internal structure, more precise interpolation, and integrated masking capabilities.
Knobs:
First & Last Corrupted Frames: For a single broken frame, these values are the same by default. For multiple consecutive broken frames, set the range to be fixed.
Note: The more consecutive broken frames you have, the less convincing the results will be.
Important: Don't use a single node for multiple non-consecutive broken frames; use separate nodes stacked up for each gap instead.
Advanced: Full Kronos controls (available in NukeX only).
Mask Input: Use this to limit the fix to a specific area of the frame.
Production Use Cases:
Broken CG: Quickly fix render glitches for temp deliveries. If only a portion of the frame is corrupted, use the Mask input to preserve the rest of the original render.
Machine Learning Artifacts: ML tools often produce great results with occasional single-frame glitches. FrameFixPro is ideal for patching these localized errors using the mask and advanced motion estimation.
