[Deciazulado]

Aeon Flux 14.09 GB 93 mins (MPEG2) = 14.09 GB/5,580 sec = 21.7 mbs
Click! 17.92 GB + 15.28 GB 107 mins (MPEG2) = 33.20 GB/6,420 sec = 44.4 mbs
Eight Below 19.62 GB 120 mins (H.264) = 19.62 GB/7,200 sec = 23.4 mbs
Fifth Element 21.67 GB 126 mins (MPEG2) = 21.67 GB/7,560 sec = 24.6 mbs
The Fugitive 21.21 GB 130 mins (MPEG2) = 21.21 GB/7,800 sec = 23.4 mbs
House of Flying Daggers 21.25 GB 119 mins (MPEG2) 21.25 GB/7,140 sec = 25.6 mbs
Swordfish 16.06 GB 99 mins (VC-1) = 16.06 GB/5,940 sec = 23.2 mbs
Tears of the Sun 20.18 121 mins (MPEG2) = 20.18 GB/7,260 sec = 23.9 mbs
Terminator 2 21.75 GB 137 mins (MPEG2) = 21.75 GB/8,220 sec = 22.7 mbs
Ultraviolet 16.77 GB 87 mins (MPEG2) = 16.77 GB/5,220 sec = 27.6 mbs

I assumed GBs as in 1024 x 1024 x 1024 x byte (like your T2 example)

That's awesome man, thanks for that info.

When we talk about video bitrate, we'd better to consider how much audio bitrate is consumed, since Warner doesn't use LPCM, while SPE and Disney use it.

Sounds about right. You want to keep MPEG2 above 20Mbps avg with some headroom for peaks.

AVC/VC-1 can exist happily in the low teens with peaks up to 20Mpbs or more.

There's no five alarm fires here at all. Both formats have the necessary space and bandwidth. If you're an lossless audio nut then clearly the bandwidth can be eaten up but frankly audio is a distant second to video in quality for a vast majority of consumers. Cheaper HTiB mated to expensive Plasmas should prove this to most.

Did you actually LOOK at the table? Unless I'm drastically reading the table wrong, only one of the AVC/VC-1 features is below 15 Mbps for the video itself -- and after you correct for what appears to be a 5% error in Mbps calculation none is below 15 Mbps.

How does that imply that "AVC/VC-1 can exist happily in the low teens"?

This table implies to me that most of the features, even using AVC or VC-1 will require video data rates in the upper teens. The average of the AVC/VC-1 features in the table is approximately 18 Mbps just for the video.

The total feature data rate, audio and video, averages about 22 Mpbs for the AVC/VC-1 features -- which is consistent with all the other data I've seen.

At this average rate a 30 GB HD DVD does, at most, 196 minutes -- well short of the HD DVD fanboys' claims of four hours and well sort of most epic films.

Great table! We can definitely use more information like this.

One little nit pick... your Mbps numbers appear to be based upon the definition of Mbps using a 1024 x 1024 definition for M. This is incorrect. The M represents 1,000,000. Thus your Mbps numbers are about 5% low.

My calculation for "M" is based on 1,000,000, not 1024 x 1024. The reason why you see 5% low number is I'm subtracting overhead rate - assuming 5% -, like subtitle data, TS/PES header information from AV rate which is simply calculated by dividing file size by run time.

I understand your rationale but disagree with it.

Are you saying this overhead is not necessary for the video file to be utilized properly? If the overhead is necessary then I would propose that the overhead should be included in the data rate. If it won't play properly without it then it should be included. While such things as subtitle data (if indeed subtitles are included on the disks for these features) might not be necessary for proper operation, TS/PES overhead (or similar header overhead) is most likely necessary and things such as this must be included in the data rate to not do so gives a false impression of the minimum data rate.

However, if subtitle data is included (it is common) then I would suggest that this should be included too since it is indeed part of the data stream (and is quite common).

Out of curiosity, I wanted to make a table comparing compression for all of them.

Used the EBU AVC/VC-1 2x > MPEG-2 factor ratio to equalize them all.

Also 2/3rds of the list is letterboxed 2.4 wide ratio transfers which needs 75% the bit rate of a full frame 16:9 image. So I multiplied the bitrate by 1.33x to compensate.

(Encoding a film image 2.40 wide that has been shrunk to fit inside the 16:9 ratio means the size of the grain to be encoded is shrunk too, making the image to be encoded less grainy, but that I didn't try to come up with a factor for. But it makes you think about why so many 2.40 movies on High Definition discs instead of 1.85 Widescreen ones (the most common ratio since 1955) which would make a better fit with a 16:9 screen and make a bigger impression to get "new customers" for the new "format", you know, the ones that go: "Why if it's HD do I still get black bars?"

Encoding black bars is easier and occupies less space


Don't know if this table correlates with the actual disc's image quality but as I said, I was curious.

Ranking order, all in full frame AVC/VC-1 equivalents:

2.40 Swordfish           27.3 mbs    0  dB (baseline)
2.40 The Last Stand      24.0 mbs  0.56 dB more compression
2.40 The Great Raid      21.6 mbs  1.02 dB more compression
2.40 Eight Below         21.2 mbs  1.10 dB more compression
2.40 The Lake House      19.7 mbs  1.42 dB more compression
1.85 Corpse Bride        18.8 mbs  1.62 dB more compression
1.85 Click               18.1 mbs  1.78 dB more compression
2.40 Four Brothers       12.8 mbs  3.29 dB more compression
2.40 Tomb Raider         12.5 mbs  3.39 dB more compression
2.40 Jay and Silent Bob  12.4 mbs  3.43 dB more compression

2.40 S.W.A.T.            11.2 mbs  3.87 dB more compression
1.85 Sleepy Hollow       11.0 mbs  3.95 dB more compression
