About
fi
lm mode detection
This mode detects whether
fi
lm or video is displayed.
When enabled, the hardware looks for tell-tale signs of 3:2 or 2:2 pull-down sequences. These are the result of converting cinema
material recorded at 24 frames-per-second to the television frequencies of 60 or 50 interlaced
fi
elds per second respectively. When
FILM conversion is detected, the original 24 frames-per-second are restored. This avoids deinterlacing artefacts, and results in a
perfect artefact-free display. Note that in some cases (video clips, scrolling newstickers,...) FILM and VIDEO material are mixed
on one screen. This may confuse the detector and cause it to go into FILM restoration mode. This will cause "jaggies" or motion
artefacts. In such cases, disabling FILM mode processing is the best cure.
Film mode detection is only for interlaced sources.
3:2 pull-down
Method used to map the 24 fps of
fi
lm onto the 30 fps (60
fi
elds) or 25 fps (50
fi
elds), so that one
fi
lm frame occupies
three video
fi
elds, the next two, etc. It means the two
fi
elds of every other video frame come from different
fi
lm frames
making operations such as rotoscoping impossible, and requiring care in editing. Some sophisticated equipment can
unravel the 3:2 sequence to allow frame-by-frame treatment and subsequently re-compose 3:2. The 3:2 sequence
repeats every
fi
ve video frames and four
fi
lm frames, the latter identi
fi
ed as A-D. Only
fi
lm frame A is fully on a video
frame and so exists at one time code only, making it the editable point of the video sequence.
2:2 pull-down
The process of transferring 24-frames/sec
fi
lm format into video by repeating each frame (used for PAL DVD’s) as two
video
fi
elds. ( AD )
Artefacts
Undesirable elements or defects in a video picture. These may occur naturally in the video process and must be
eliminated in order to achieve a high-quality picture. Most common in analog are cross color and cross luminance.
Most common in digital are macroblocks, which resemble pixelation of the video image.
