Frame Mixer
Temporal frame mixing for smooth motion when source and display framerates differ. When the source framerate does not evenly divide the display refresh rate (e.g., 24fps on a 60Hz display), frame mixing blends adjacent frames to reduce judder.
Available Options
| Mixer | Internal Name | Description |
|---|---|---|
| None (disabled) | none | Show the nearest frame to target PTS, no blending |
| Oversample | oversample | Only mix edge frames while preserving the source FPS |
| Hermite | hermite | Hermite-weighted frame mixing |
| Linear | linear | Linear frame mixing |
| Cubic | cubic | Cubic B-spline frame mixing |
Default: None (none) -- frame mixing is disabled.
Recommended Settings
- None provides the lowest latency (1 frame) and is recommended for real-time capture workflows such as DeckLink input.
- Oversample is a good starting point for playback. It only blends frames at cadence boundaries, preserving the original motion cadence while smoothing transitions. Note that it adds approximately 6 frames of latency for temporal interpolation.
- Linear and Hermite produce smoother blending across all frames but introduce a slight "soap opera" look on film content.
- Cubic uses a B-spline kernel for the smoothest interpolation but is the most computationally expensive option.
