Introduction
fieldanalysis scans video for interlacing artifacts and detects progressive / interlaced / telecined video. It also determines the major field for interlaced video.
Parameters
Default values are shown in
[green] in square brackets.
- interlacediff Minimum temporal inter-field difference for detecting interlaced video (1.0-oo) [1.5]
-
- unknowndiff Maximum inter-frame change vs. detail differences for neglecting interlaced video (1.0-oo) [1.5]
-
- progressivediff Minimum inter-frame change vs. detail differences for detecting progressive video (unknowndiff-oo) [8]
-
- progressivechange Minimum temporal change needed for detecting progressive video (0-oo) [0.2]
-
- changedifmore Minimum temporal change for detecting truly changed frames (0-65025) [10]
-
- forcetelecinedetect Detect telecine even on non-NTSC (29.97fps) video
-
- verbose Output analysis for every frame (0-2) [0]
-
- outdiff Output internal debug frames as luminance of YUV video (see source) (0-11) [0]
