Texas Holders said:Just rough estimates based on personal experience ripping blu-rays and the size of files on iTunes. iTunes 720p HD movies are roughly 2 GB per hour. I think Apple has even stated that their SD videos are around 1 GB per hour and HD 2 GB per hour. I have purchased several TV shows in HD off of iTunes and they are generally around 1.5 GB for a 40-45 minute show. It does depend on the setting you are using to encode on Handbrake, but most of the TV shows/movies I have ripped in 1080p are around 4 GB per hour. This makes sense since 1080p has roughly twice the pixel density over 720p. You do get a bit of a break in size with feature films since Handbrake doesn't include the black bars when it encodes it. This number is dependent on the final quality you really want though. Also, keep in mind that when you pull the mkv, it takes everything including menus, alternate scenes, extra languages, closed captioning, etc... The actual movie itself isn't nearly that large. On the other hand, digital media is nowhere close to replacing blu-rays as some might have you believe as you are sacrificing quality a bit to make the file size more managable. If I have the choice to watch a movie on blu-ray or a 1080p digital copy, I choose blu-ray every time.

Ok...thanks, I get what you are saying about movies you get from apple. They likely do have a certain way they do they encodes to ensure uniform quality and file size.
When you use makemkv on a blu ray, you don't get any menus in the file, unless you decide to get them. But I make mkvs that are bit perfect, but have no menus. No subtitles, and only a single high def soundtrack. Depending on the movie, that file can be 40GB+, but most of them are not that big.
