Space issues on Blu-rays regarding tv shows - Blu-ray Forum

mcdaking84 · 11-23-2009, 12:55 AM

I remember reading in the past that a single blu ray disc could hold multiple seasons of a single show. Is this true and are companies just lazy or was I just hearing things?

I find it hard to believe that 4 episodes of 24 can fit a single dvd and no improvement can be made so I have 6 blu ray discs of 24

It could... in SD.
Realistically you're not going to put more than 4 hours of HD video on one disc at an acceptable quality, especially a TV show that takes up the full HD frame.

yeah I get that an hd transfer takes up moer space and i am a bit of a noob but doesn't a blu ray hold 25 or 50 gb of memory?

how could 4 episodes fill that up?

Assuming an average bitrate for the whole stream (including video, audio, and subtitles) of 32mbps, that's about 4MB a second, 240MB a minute, and 10GB for an hour-long network show (~43 minutes without commercials). So four episodes is about right, if they also have extras on the disc or are using higher bitrates.

According to DVDBeaver.com:

Transformers: Revenge of the Fallen takes up about 45gbs of space with one lossless audio track, three lossy tracks, and the video.

One disc of The Prisoner: The Complete Series also takes up about 46gbs of space and that's with three lossy tracks plus the video for each episode. Each episode takes up about 8gbs of space on each disc.

So basically, in the same space as one DVD-9, you could fit one episode of The Prisoner in HD video with three lossy tracks. That means a 17 disc set without extras!

You're also comparing apples and oranges

The Prisoner is a low action show. Lots of very static shots, and you're comparing it to Michael Bay which is totally fast cut kinetic high action. Star Trek does fine at 14-15mbps average because of this. But JJTrek is running double that because they're completely opposite in their stylistic choices, and the kinds of bitrate it takes to maintain quality

Okay...

Well, the Star Trek: Season One BD discs are between 43 to 48 GBs with each episode around 7 to 12gbs a piece.
