enums ¶

Bases: CustomEnum

Enum representing different decimation patterns for IVTC (Inverse Telecine) processes.

These patterns are used to remove duplicate frames after double weaving fields into frames. Each pattern defines a sequence of frame indices to keep during decimation.

Methods:

• decimate –

  Apply the decimation pattern to a video clip with the given pattern index.

Attributes:

• CYCLE_05 –

  Pattern for standard frame-based 2:3 pulldown.

• CYCLE_08 –

  Pattern for 2:3:3:2 pulldown.

• CYCLE_10 –

  Pattern for standard field-based 2:3 pulldown.

• cycle (int) –

  Get the total number of available pattern variations for this cycle.

• pattern_length (int) –

  Get the length of the pattern cycle in frames.

CYCLE_05 = [
    [0, 1, 3, 4],
    [0, 1, 2, 4],
    [0, 1, 2, 3],
    [1, 2, 3, 4],
    [0, 2, 3, 4],
]

CYCLE_08 = [
    [0, 3, 4, 6],
    [0, 2, 5, 6],
    [0, 2, 4, 7],
    [0, 2, 4, 7],
    [1, 2, 4, 6],
]

CYCLE_10 = [
    [0, 3, 6, 8],
    [0, 2, 5, 8],
    [0, 2, 4, 7],
    [2, 4, 6, 9],
    [1, 4, 6, 8],
]

    assert 0 <= pattern < self.cycle

    return core.std.SelectEvery(clip, self.pattern_length, self.value[pattern])

Bases: CustomIntEnum

Enum representing different matching modes for VFM.

The mode determines the strategy used for matching fields and frames. Higher modes generally offer better matching in complex scenarios but may introduce more risk of jerkiness or duplicate frames.

Attributes:

• THREE_WAY_MATCH –

  3-way match (p/c/n).

• THREE_WAY_MATCH_FOURTH_FIFTH –

  3-way match + 4th/5th matches on combed (p/c/n + u/b).

• TWO_WAY_MATCH –

  2-way match (p/c). Safest option, but may output combed frames in cases of bad edits or blended fields.

• TWO_WAY_MATCH_THIRD_COMBED –

  2-way match + 3rd match on combed (p/c + n). Default mode.

• TWO_WAY_MATCH_THIRD_FOURTH_FIFTH –

  2-way match + 3rd match on combed + 4th/5th matches if still combed (p/c + n + u/b).

• TWO_WAY_MATCH_THIRD_SAME_ORDER –

  2-way match + 3rd match (same order) on combed (p/c + u).

THREE_WAY_MATCH = 4

THREE_WAY_MATCH_FOURTH_FIFTH = 5

TWO_WAY_MATCH = 0

TWO_WAY_MATCH_THIRD_COMBED = 1
