Filmmode detection:
[On]o r [Off]
Detectsin the [on] mode if the source is film or video. Usethe ENTER key to toggle between [on] or [off]
Whenenabled, the hardware looks for tell-tale signs of 3:2 or 2:2 pull-down sequ ences. These are the
resultof converting cinema material recorded at 24 frames-per-second to the television frequencies of
60or 50 interlaced fields 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-freedispla y. 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
restorationmode. This will cause "jaggies" or motion artefacts. In such cases, disabling FILM mode
processing is the best cure.
BannerProtect: [On]
or [Off]
Onlyactive when film mode detection is in the on position. Use the ENTER key to toggle between
[on] or [off].
FILMmode processing normally processes the entire display, but this may cause problems on sources
wherevideo and F ILM content are mixed. One very common example is scrolling banners at the
bottomof the screen (e.g. financial news). For those cases, the "banner protect" feature will force the
bottomquarter of the screen to be always processed in VIDEO mode, regardless of the rest of the
screen, which may be either video or FILM mode.
3:2 pull-down
Methodused to map the 24 fps offilm onto the 30 fps (60 fields) or 25 fps (50 fields), so th atone filmframe occupies
threevideo fields, the next two, etc. Itm eans the two fields of every other video frame come from different film frames
makingoperations such asrotoscoping 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
repeatsevery five video frames and four film frames, the latter identified as A-D. On lyfilm frame A is fully on a video
frameand so exists at one time code only, making it the editable point of the video sequence.
2:2 pull-down
Theprocess of transferring 24-frames/sec film format into video by repeating each frame (used for PAL DVD’s) as two
video fields. ( 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.
