How much Compression with a Blu Ray disc is too much?

    I was wondering how much compression is too much when compressing a movie down to a BD-25 disc? At what percentage of compression will you start to see the quality of video suffer? Anybody have any thoughts?

    How much is too much?

    Either you compress it down to fit on a BD-25 or don't and put it on a BD-50. The question would then be, how much can your wallet or purse suffer by buying BD-50s as opposed to BD-25s? The 50s are still quite pricey! Then it comes down to the next question ... just how GOOD is the movie and does it "justify" putting it on a 50? I've copied my $40 Avatar movie to a 25 and didn't really see any video degradation. Hope that answered your question :rolleyes:

    Or do you really want all that BS that comes with a movie, or would you rather just pop it in and play? Movie only all the way!! Thats just me!

    Me too,DZ. Just bought my copy of Tron. Removed hd audio and ending credits and it fit. I'm set at 23000 so as not to burn to the edge. Only way to go, pop it in and watch the movie.

    wish i knew how to remove the credits :-(

    Choose Main Movie when you're copying to the HDD and click on the bottom small window bar that says something about Title/Chapters and it will allow you to choose what chapter to start and end the movie. Most likely you just remove the last chapter which is usually the end credits. I did it with Sin City to get it to fit uncompressed on a 25GB disc with HD audio selected.

    Cutting end credits

    Here's some screen shots on how to cut the credits







    Thanks to SuperFist for pointing this out! I never noticed it before!

    Mdy4Blues is THE MAN! :rolleyes:

    Some of us do want the BS and extra stuff not just the movie. That's great if Main Movie only suites you but some of us are still waiting for a Blu-Ray Cuntomize feature like on DVD Copy so we can pull out the useless previews and what seems to be extra copies of the movies embedded in the disc to make it bigger and just have the movie, menus and extras with minimal compression. Extra unneeded padding seems to be the reason that movies are compressed so low. I've had many movies that are supposed to be the same quality(56-60%) and are roughly the same disc size within .5GB and the compressed bit rate widely varies. Some recompress at about 12000-15000 kbps and others recompress at 8000-10000 kbps even after removing HD audio and the only thing the seem to have in common are what seem to be 2-3 extra copies that have the same or similar runtimes as the first title. Last word was that the developers are still working on Customize but it is hopefully coming. Once again if you want the main movie that's great but if you don't you shouldn't let the"why do you the want the extras and BS" attitude change you from want you want for your Blu-Rays. And to DVDFabs' credit those movies that came out with a 8000-10000kbps compression range the quality was actually quite good. Still better looking quality than the compressed HD on most networks.

    Don't know if it's a quote from my post, but as I said I want to pop the movie in and watch that's it! Like I said it's me I have all the movie channels and when a movie I have backed up comes on and is played continously having it on BD is moot. So I use BDRE and erase and backup something new. New features are gonna be great for Fab and all the users, this is not an attitude it's just how I do it!

    Compression to me defeats the whole purpose of Blu-Ray. Dvd not so much. My general rule is 90% of the original for dvd. Blu-Ray I don't compress. I know some of you might think I'm crazy for spending bucket loads of money on 50gb discs. but I like to retain the original quality when backing up my Blu-Rays. JMHO!

    Exactly! I use BDRE 50gb for the big movies and 25gb for the movies that fit! Never compress!

    No doubt you've considered this and I'm probably preaching to the choir, but given the relative costs, why not archive to hdds?

    You can pick up a 2 TB Samsung for $74.99, shipped....available at newegg until 4/28.
    Throw in a media player like my Argosy for about $89 and you're way ahead.

    My bet is the hdd will outlast your burned BDs.
    Even so, no matter since you've always got the originals

    No more expensive or "bad discs".

    You'll never have to get up from your comfy chair again...not to look for or change a disc...:cool:

    Maineman is now certainly converted !!!

    :D:o:)

    Now you just have to get the house and your network set up properly so you really can take advantage!!!

    I've never really put much thought into that. but it's something i would consider. but i have a few questions.
    1. i have an expansive collection of dvds and blu-rays. What format would i need to save the blu rays and dvds so that they will play on the argosy or some other media player? Not to mention i would need about 25-30TB to do this.
    2. Will i lose any video quality during playback. Is playback similar to bd/dvd playback,eg: chapters, menus?
    3. will these media players like the Argosy play HD audio and 3D?
    4. Can i still playback Blu-Rays at 1080p 24hz?

    See my comments below in RED

    You can save them as an uncompressed ISO & retain all quality but most of us use h264 MKV's. This can be compressed or uncompressed and this is a very subjective issue. You have to try it yourself. I would suggest that you will be surprised with the results.

    Maineman would be best to comment on some of the results on the Argosy.

    2. Will i lose any video quality during playback. Is playback similar to bd/dvd playback,eg: chapters, menus?

    See above

    3. will these media players like the Argosy play HD audio and 3D?

    I don't know about this particular model, but there are models that I know that will play HD & 3D,,,

    4. Can i still playback Blu-Rays at 1080p 24hz?

    This terminology is just an advertising B/S beatup. Of course YES!!!

    I have a pretty high end system and everything is run through HDMI but the receiver has 4 inputs and they are all being used. When I pick up another receiver with more inputs I probably will get with the times! I use BDRE and just erase over them I have a huge DVD/Bluray collection but only watch them one time so I thinks its a waste and don't want to collect any more movies!! Thanks for the advice!!

    Well DZ, seeing what you have said, it's got me beat why you even bother backing up your disks at all.
