BCC Deinterlace
Category: BCC Film Style
Effect Name: BCC Deinterlace
The BCC Deinterlace filter, part of the BCC Film Style category, converts interlaced video clips into progressive-scan frames, similar to footage shot on film. The filter can also simulate TeleCine-style pulldown and convert 29.97 fps NTSC video into 24 fps film-style frames.
Working with the Filter
Presets and Common Controls
- BCC filters come with a library of factory installed presets plus the ability to create your own custom presets and preview them with the BCC FX Browserβ’.
- BCC filters also include common controls that configure global effect preferences and other host-specific effect settings.

Effect Controls
Mocha Mask and Track
Continuum effects include integrated masking and matte tools that allow you to restrict the effect to specific regions of the image.
- Mocha masks: used to create custom spline masks. Mocha also includes Matte Assist ML and Matte Refine ML, which use machine learning to generate and track masks.
- Pixel Chooser: used to generate geometric shapes, gradients, or mattes based on channel, luma, or color-based selections. Additionally, an AI depth map generator, and an AI-powered face detection model allow for precise control of masks and mattes.
Note: Mocha can also be used to drive geometric parameters. See the Mocha Motion Tracker documentation for details.
For more information, see Mocha and Pixel Chooser.
Compare Mode
The Compare Mode is used to view the filtered result alongside the original source layer. Several split-screen and side-by-side display options are available.
For more information, see Compare Mode.
Important Notes
If you are combining the BCC Deinterlace filter with other film filters such as:
- BCC Film Damage
- BCC Film Grain
- BCC Film Process
- BCC Match Grain
Apply BCC Deinterlace first. The filter performs best when working with the original, unprocessed pixels.
Important Note for After Effects Users
- Clips processed with this filter must have Separate Fields set to Off in the Interpret Footage dialog.
- Output rendering must also have Field Render set to Off.
- Frame Blending should not be enabled.
Deinterlacing leaves the first input field unchanged (typically the lower field for DV). The second field is synthesized by interpolating pixels where motion artifacts such as combing appear.
A motion mask determines where interpolation occurs. The Motion Sensitivity and Motion Filter Size parameters allow you to fine-tune this mask.
- Operation Determines which interpolation method the filter performs.
- View Motion Mask: Displays a black-and-white motion mask showing where interpolation will occur. White pixels will be interpolated, black pixels will remain unchanged.
- Only Deinterlace: Converts interlaced video to progressive frames without altering the frame rate. This helps remove combing artifacts.
- Simulate Pulldown: Simulates the 3:2 pulldown effect used when converting film to NTSC video. The filter selects the fields closest in time to the target 24 fps frames and assembles them into a pulldown pattern.
- 29.97i β 23.976p: Creates film-rate progressive frames from interlaced NTSC footage.
- Motion Sensitivity: Sets the input field order to match the source footage. Select from Upper or Lower field order.
- Input Field Order: Determines the threshold of the motion detection mask. Higher values cause more pixels to be interpolated.
- Motion Filter Size: Determines the number of pixels analyzed when detecting interlace artifacts. Larger values improve artifact detection but may reduce image detail.
- Interpolation Slant Determines how diagonal edges are analyzed during interpolation.
- 0: Vertical interpolation only.
- 1: Includes 45-degree diagonal lines (default).
- 2: Examines additional pixels to better preserve diagonal edges.
- Pulldown Pattern Selects the pulldown cadence when simulating pulldown using "W" (whole) and "S" (split) frames to map frames across video fields and prevent motion jitter.
Available patterns:
- WWWSS
- WWSSW
- WSSWW
- SSWWW
- SWWWS
- Output Field OrderDetermines output field order when pulldown simulation is used. Select from Upper or Lower field order.
- Mix with Original: Blends the source and filtered images. Use this parameter to animate the effect from the unfiltered to the filtered image without adjusting other settings, or to reduce the effect of the filter by mixing it with the source image.
