A discussion on another thread has prompted me to compile this chart. It tracks dual-layer discs and codecs used, month by month. Percentages are calculated, both for the month, and for the format's existence.


I have also included colums for the despised "MPEG-on-single-layer" titles.


Code:

Interesting perspective, Grubert. This is an important discussion, IMO.

But what the OP in the "other thread" was saying was accurate.


70% of BD titles currently available are Single Layer BD25 releases

70% of BD-exclusive titles currently available are Mpeg2, with 63% of all BD releases available being Mpeg2 also

70% of all BD25 Single Layer releases are encoded in Mpeg2

50% of all BD releases available are Mpeg encodings in Single Layer BD25 discs


There is nothing misleading about this.


Even if every BD disc released for the next year was a BD50 with VC1 or AVC encoding, it still could not cut these percentages in half.

Well first of all, obviously it would.


But second of all, I think what people suspect you of is trying to paint a picture that indicates the snapshot present is reflective also of the trend - which is what most people whether consciously or subconsciously would be concerned with. I for one share that suspicion of your intentions.


What Grubert is doing - not so much to prove you wrong per se - is to show that the majority of upcoming releases, and indeed recently released titles as well, are on BD50. And I think this is important context which you - seemingly purposefully - decided to omit. Which begs then the question, what were you trying to show with your OP, and for what purpose?


You'll have to understand if you're suspected immediately of the cynical 'infobites' for which you are known.

Exactly. We were told 70 percent of Blu-rays are SL. Some of us said, okay, but that's not the whole picture. If the ratio was 82% at the beginning of the year, that change is relevant too.
