Just when I thought they couldn't do worse than throwing away 50% of the information from the source, they managed to do worse! I spent quite a bit of time trying to figure out what the hell they did, but since all I have is the final product, I can't guarantee that I got it right. I can guarantee, however, that some idiots really messed this one up.
First of all, the entire main concert footage is badly pre-deinterlaced. Just this process alone reduces the useful information to half. For more information about this, check out Mizuki Nana's "Live Sensation" and "Live Rainbow" DVD listings. Believe it or not, this goes even further.
After manually looking at many many frames, I've found this pattern of active (1) and inactive (0) frames in the video stream:
11110/11101/11011/11011/10111/10111
01111/01110/11101/11101/11011/11011
10111/01111/01110/11110/11101/11011
11011/10111/10111/01111/01110/11101
11101/11011/11011/10111/01111/01110
(repeat)
I don't know if the original was shot at 60 (59.94) fields per second
or 24 frames per second. There are hints indicating both, so it may
even be mixed. Somehow, the final video only contains 23.4 (23.3766)
frames per second. If we were to assume NTSC adjusted master frame
rate of 23.976, that means that the rate of frame drop is 3 every 5
seconds.
Since it does not follow continuous 3:2 pattern due to occasionally and almost irregularly dropped frames (fields?), the whole thing jitters like mad. Throw in the fact that each frame only contains 720x240 of information at best, it makes for a brain numbing viewing experience.
I am so perplexed, stupefied, dumbfounded, and flabbergasted about the whole thing, I can't think of anything more to write.
Only the odd fields contain useful information. Even fields are all derived from the adjacent odd fields and contain no new information.
