Deinterlace

Converts between interlaced and progressive video. Use it to clean up interlaced sources (1080i broadcast feeds, 480i/NTSC SD material) so they look correct on progressive displays, or — going the other way — to interlace a progressive signal for traditional broadcast outputs that require it. Several algorithms are available covering the trade-off between latency and quality, plus an optional 3:2 pulldown for 24p-to-60i conversion.

Deinterlace - Settings

Mode

Mode — what the operator should do with the incoming frames.

Property	Description
`Mode`	What to do with the incoming video. [default=Deinterlace]. `Deinterlace` converts interlaced sources to progressive — pick this for cleaning up 1080i or 480i feeds. `Interlace` produces an interlaced signal from progressive input, for legacy broadcast outputs. `Passthrough` lets the input through unchanged.

Deinterlace

Deinterlace — algorithm and field handling for converting interlaced input to progressive.

Property	Description
`Method`	Algorithm used to deinterlace the input. [default=MotionAdaptive]. `Bob` doubles each field line — fastest, lowest latency, but visibly soft. `Weave` interleaves fields with zero latency but combs on motion. `Blend` averages adjacent fields — clean but slightly soft. `Motion Adaptive` blends weave on still parts and interpolation on moving parts — best balance of sharpness and motion handling. `YADIF` is a higher-quality temporal filter; both `Motion Adaptive` and `YADIF` add one frame of latency.
`Field Order`	Which field of the interlaced source comes first in time. [default=TopFieldFirst]. `TopFieldFirst` (TFF) is standard for 1080i broadcast. `BottomFieldFirst` (BFF) is standard for 480i/NTSC SD. Getting this wrong on motion causes visible jitter — try the other setting if the deinterlaced output looks wrong.
`Field Parity`	Which field to anchor on for Bob-style algorithms. [default=Top]. `Top` uses the even lines as the reference field. `Bottom` uses the odd lines. Mostly only relevant for the Bob method.

Motion Adaptive / YADIF

Motion Adaptive / YADIF — fine-tuning controls for the smarter deinterlace methods.

Property	Description
`Edge Threshold`	How much motion is needed before the operator switches from weave to interpolation. [min=1, max=100, default=30]. Only used by the Motion Adaptive method. Higher values prefer weave (sharper on static parts) but allow more combing on motion. Lower values switch to interpolation more aggressively (smoother motion, slightly softer stills).
`Spatial Weight`	Balance between spatial (within-frame) and temporal (across-frames) interpolation. [min=0, max=100, default=50]. Used by the Motion Adaptive and YADIF methods. Higher values lean on spatial detail (better at preserving fine vertical patterns); lower values lean on temporal data (smoother motion). 50 is a good default for most material.

Interlace

Interlace — settings used when producing an interlaced signal from progressive input.

Property	Description
`Output Field Order`	Field order for the interlaced output. [default=TopFieldFirst]. Match what the downstream device expects: TFF for 1080i, BFF for 480i/NTSC SD.
`Pulldown`	Optional 3:2 pulldown for converting 24p material to 60i. [default=None]. `None` produces a straight 2:2 interlaced output. `Pulldown32` runs a 3:2 pulldown pattern — used to send 24p film-style content over 60i broadcast.

Diagnostics

Diagnostics — visualisations to help tune the deinterlacer.

Property	Description
`Show Motion Map`	When true, overlays the motion-detection map used by Motion Adaptive. [default=false]. Green pixels mark areas treated as static (weave); red pixels mark areas treated as moving (interpolate). Useful while tuning `EdgeThreshold` — disable for normal use. Only relevant when `Method` is `MotionAdaptive`.
`Reset`	Reset all settings to their defaults (Deinterlace mode, Motion Adaptive, TFF, top-field parity, edge threshold 30, spatial weight 50, no pulldown, no motion map).
