Static Paterns contains: Picture Controls, Geometry, Gray Scale, Half Patterns. All of these contain a number of test patterns to help calibrate a video processor.
I could not think of a better name than "half patterns". These map to the patterns in the VP30 where half of the image is transparent. The idea is you would pull up that pattern on the disc and then go to it on the VP30. This will allow you to verify color space conversion, as an example. The bars may not line up exactly due to pixel cropping in a player, but the colors should match.
I need to explain the bad edit tests located under source adaptive. It contains the following bad edits:
# ...AABBBCCDDD-BBBCCDDDAA... (...3-2-3-|3-2...)
# ...AABBBCCDDD-DDAABBBCCD... (...3-2-3-|2-2-3-2...)
#
# ...BCCDDDAABB-BBBCCDDDAA... (...3-2-2-|3-2...) *
# ...BCCDDDAABB-AABBBCCDDD... (...3-2-2-|2-3-2...) *
# ...BCCDDDAABB-DDAABBBCCD... (...3-2-2-|2-2-3-2...)
#
# ...BBBCCDDDAA-AABBBCCDDD... (...3-2-|2-3-2...)
# ...BBBCCDDDAA-DDAABBBCCD... (...3-2-|2-2-3-2...)
These are 7 of the 25 possible bad edits with 2-3. These are the only 7 that do not contain a single field. The purpose of this test is to see if a processor can track across an edit w/o dropping to video.
The first time you see the text, this means the next edit, or loop, will contain that edit. At that point the text color will invert but remain the same. This gives you time to read what the edit was, incase it dropped out of film lock. The next edit, however, will actually be clean. So you have bad, clean, bad, clean, etc...
If a processor drops lock, it should only occur on the first of each. If it occurs on the clean edits too, that is even worse.
The montage was edited by hand to ensure that almost every cut is a bad edit. The cross fades are usually 2-3 to 2-2, 2-2 to 2-3 or 2-3 to 2-3 where one 2-3 is out of phase with the other.
The montage is more enjoyable with audio.
) edition of this test disc. If so, you just became my new best friend!
