What is the difference between these two files at the bottom? The top one is about 2 GB and the bottom is about 10. Is there a big difference in quality? I connect my laptop to my TV to watch my content, so would I notice a difference? Thanks

BDRip is like a small DVDRip type of a show or episodes. It's from a blu ray, but the size of a dvd rip. The 720 is High Definition and is the best choice out of the two. It has a better bitrate and resolution |

The first one is XviD and will obviously have a vastly smaller bitrate and/or frame size, judging from the sizes given. x264 rips (second one) will generally 'look better', especially at high bitrates (although I have seen some pretty impressive v-high bitrate XviD rips - although they're pretty rare, and huge). Considering the difference in size and difference in encoders used, it's safe to say that: yes, you would definitely see the difference! |

Both are BlurayRips, and as only one upload mentioned the resolution, you need to look at the "Xvid" and the "x264" part to safely assume which is better quality. x264 and Xvid are software used for encoding. This is what will make the decision what you want. If an encoder would want to encode a movie. Let's say The Dark Knight. And the encoder wants to upload the movie twice, where one upload is The Dark Knight encoded with x264, and the other upload is also The Dark Knight but instead encoded with Xvid. And he decides that both the uploads are exactly 1gigabyte each. Than the 1gigabyte x264 would most likely be better quality, when compared to the 1gigabyte Xvid.

Actually only one of those releases has been ripped from the Bluray & that is the "720p Bluray" one. Of course there is no such thing as a 720p Bluray a while back the release groups decided to rename "720p BDRip" to "720p Bluray" the Bluray part is just the source used a "720p Bluray" will usually be a 720p mkv once downloaded The one marked BDRip is really a m-HD "mini HD" they are more usually referred to as BRRips, HDRip's, m720p. BDRip should indicate a first generation rip from the Bluray the m-HD versions are ripped from a 720p/1080p MKV source ie the first gen BDRip which makes them second generation rips & they are not classed as being HD quality. m-HD's can be any res from 480p(non HD) - 1080p I have seen them as small as 400MB we only allow these in the std Movie forum as their quality is not good enough for the HD forum. As to the codec used that is more subjective while x264 is in general better than Xvid or DivX in practice it mainly indicates what type of video container has been used ie mkv or avi. An x264 is usually an mkv & Xvid an avi if the video bitrate is high enough both can be of HD quality though Xvid is more common with DVDRips than BDRips. These days most things will play mkv's but I used to have to convert mkv's to MP4's for playback on my PS3 & my 360 preferred avi's To cut this short both releases are from the same group the 720p Bluray has been ripped from the actual Bluray but the other one the BDRip has been ripped from the other the aforementioned 720p Bluray release & will be of a lot less quality...

Thanks for the explanation TheWang, wasn't aware of it either. And jeez, some of these acronyms in the warez world can really be obscure. :p Eitherway, looking at which encoder is used is faster in these case imo.

Voodu is right though, both are ripped from a Bluray quality source. The filesharefreak.com/2008/11/19/blu-ray-brrip-bdrip-two-new-xvid-hd-formats article backs that up. One thing that would be alot more beneficial for the general pulbic is that people should stop using the term "Bluray", as it can be interpreted to anything. Ranging from "Bluray quality" to "Ripped from the Bluray Disc" to "Re-encoded from an already existing BDRip". It would be alot more clear if people who pump out releases would just either stick with BDRip or BRRip, as that should be enough to cover the spectrum. |

| Insane ![]() ![]() ![]() Join Date: Jan 2008 Posts: 21,553 | Both are ripped from Bluray. BDRip = Bluray disc/image source. BRRip = source is an existing rip No, 720p x264 rips from BluRay source were never called BDRip. Not in the scene anyway. Go check x264 high-def movie standards revision 1 from 2007. Its kind of irrelevant to talk about non-scene terms because these groups can make up whatever terms they want. When I refer to release's I am talking about any any encode from anyone when I joined here back in 2008 there was very little 1080p about & none of the posts here had Bluray in the title they were just known as BDRips as anything that is ripped from a Bluray can be called a BDRip at that time BRRip was taken to mean the same thing. Also at that time Toshiba's HD-DVD format was still around so rips from those were sometimes called HDRips. Once the HD-DVD format died of & a new codec x264 was in use what were the equivalent of "720p BDRips" became known as "x264 720p Bluray" there is no such thing as an original 720p Bluray disc. The terms BRRip & HDRip dropped out of use for a time at least on this forum until some brightspark came up with the idea of re-ripping "x264 720p Bluray" release's reducing the overall size & video bitrates though often keeping the res of said release 720p or 1080p though odd ones appeared as well 810p & others. These 2nd generation rips have been called many things on different forums m-HD, BRRip, HDRip, m720p just to name a few. These have a res that is covered by 720p to 1080p but they are not considered to be good enough to qualify as HD as their overall quality is much lower than the originals. For example here is one I moved earlier a 1.4GB 1080p >>> http://tehparadox.com/forum/f56/mirr...2/#post8780782 Genre: Adventure | Comedy | Drama Stars: Lily Collins, Julia Roberts and Armie Hammer Format: MKV Duration: 1h 45mn Video: 1920 × 1040 | 1 779 Kbps @ 23.976 fps Audio: AAC | 48.0 KHz / 24.0 KHz Source: 1080p.BluRay.x264-SECTOR7 Encoder: ShahBct From the supplied info it is clear it was sourced from the "x264 1080p Sector7" release not the actual Bluray if you check the info on BRRips you will see many x264 720p or 1080p releases given as the source Full Bluray releases do not have x264 in the title or release name.

A 720p or 1080p res does not means its actual HD it just has 720 or 1080 vertical lines which is why we use the term "HD Quality" if its not good enough then it doesn't get to stay in the HD forums. We do not have an in-between forum for movies so m-HD, m720p, BRRip's, HDRips, HDCams, Upscales go in the std Movie forums any found in the HD forum will be warned on & moved. With TV Shows they all go in the same forum regardless of res so "TV Shows" is for any TV Show whether std def or Full Bluray. |

| Insane ![]() ![]() ![]() Join Date: Jan 2008 Posts: 21,553 | An average "x264 720p Bluray" release is about 4.36GB's with a video bitrate about 4000Kbps which is only about a tenth of the actual Bluray which will be 40GB's plus with a video bitrate about 36Mbps or 36,000Kbps if the same Kb range is used As to a 1080p mkv "x264 1080p Bluray" will be approx 10GB with an 8000Kbps video bitrate Remux now where getting there about 30GB's with a 18-24Mbps video bitrate There is no doubt Full Bluray is still best & the current quality mark... |

I tend to agree that scene used standarts name.year.720p.BluRay.x264-group is confusing and naming 720p.BDRip I see on some non scene sites (mainly russian) more explains itself (suggesting its "rip" (encode) of Bluray).

But HD is used to describe a resolution (or groups of resolution), not a quality. For a std 90 min movie we expect the min size to be 4.37GB & the video bitrate to be at least 4000Kbps (Animation can be lower as it does not require as much bandwidth) Any thing below that should be posted in the general movie forum just known as "Movies" or it risks being warned on & moved or deleted Seemingly under your low HD standards a non HD title upscaled to 720p would class as HD purely because it has 720 vertical lines. With their many rules the scene would nuke a HD release if it turned out to be from an upscaled source. Last edited by TheWang; 06-18-12 at 05:05 AM. |
