Average file size of a Blu-Ray movie? (in GB)?

Question

What is the average file size of a Blu Ray movie (in GB)?

Stripped down to just the movie itself, with only English subtitles but no others, and only English audio?

I recently downloaded a 16.88 GB 1080p movie. It came with multiple audio and subtitles. Does this increase the filesize, thus making the film run slower? I am using Windows XP.

Is there a difference between regular Blu Ray and 'Proper' Blu Ray?

Any help anyone can give me here is much appreciated, cheers. :)

Answer 1

The length of movies varies widely, which directly affects the amount of storage space a movie will occupy. Combined with the additional variables from which one may choose to encode movies on Blu-ray Disc (BD) Read-Only, or BD-ROM, specifying a single number wouldn’t really amount to much. You would be far better served if you used the total average bit-rate for the BD compliant audio and video codecs that are of interest to you. This would provide you with a much more accurate average bit-rate from which you could derive a more meaningful storage capacity requirement based on a specific or average movie run-time. The resources below should easily help you find the information you want.



For whatever good it may serve, using Microsoft Excel and Cinema Squid’s latest tab-delimited list¹ of 4296 Blu-ray Disc movie specs, of which 4066 are reported as being encoded as 1080p24, and neglecting specific codecs as well as the number of channels in the main audio track, I calculated an overall average Movie Size of 27,367,873,653 bytes and an overall average combined (audio and video) bit-rate of 31.5621 megabits per second (Mbps). Using 1 GB = 1,073,741,824 bytes to convert bytes to gigabytes I calculated an average Movie Size of 25.4883 GB.

A: The file size or the number of audio streams has no bearing on the encoded frame-rate of the movie.

If you're talking about the uncompressed digital video file that an editor would work with, the whole film would be well over 150 GB. If you're working with HD DV it's about 9 GB for every ten minutes of footage, but converting 35MM film print to uncompressed DV it's even larger. I'd say for a two-hour long film, shot in 35MM, the uncompressed DV file size would be about 200 GB. When they put a movie onto DVD they compress it down to about 7 to 8 GB, but on Blu-Ray it's over twice as large.

Answer 5

10-20 GB.



Single layer Blu-ray disks hold 25 GB (and double layer hold 50 GB), but many disks contain a lot of files for extras, uncompressed audio, extra languages, etc.



I don't know what you mean by "regular Blu-ray" and "proper" Blu-ray. All Blu-ray disks are proper (otherwise it isn't Blu-ray). You may mean rental only versions vs retail versions ... the former come without the extras so take up less space.
