    hi, this have to be a simple question:

    I have a DVD 3.8gb I want a extract with handrake to ANY format (mkv avi etc...) BUT without loose any quality. I see a lot presets and settings and bla bla bla export to ipod apple tv bla bla bla... I dont want anything of that I want the same DVD of the dvd that I have but In a single format.

    I put for test, mkv, constant quality 100% and for 8min of the dvd are 2gb! soooo bad... obvious that dont work is a lot size, I want a 3.8gb or any size other normal size (the space dont matter) but get the same quality of the dvd.

    my point is simple I dont want compress of 700mb avi and things like that, I want the same DVD quality that I have in this 3.8gb but in a single format.

    any simple preset for do this?

    Handbrake uses highly compressive and lossy MPEG-4 codecs like H264.
    Video DVDs use a highly compressive and lossy codec called MPEG-2.

    As both codecs are lossy, you won't loose that much visible and noticeable visual information during the transcoding (conversion) anyway.

    You can try to up the data rate to whatever fits the final size you wish to have and the length of the video.

    But that will not give you more information, as there is not so much information there in the first place.

    As MPEG-4 is more advanced than MPEG-2, you can get the same visual and qualitative results with less HDD space taken than with an MPEG-2 encoded video.

    Example: 1GB of MPEG-4 encoded video of a 90 minute movie can have the same visual quality as the 6GB MPEG-2 encoded source.

    Btw, MPEG-2 encoded video on a video DVD uses up to 8/9 Mbit/S as a data rate, that's 1MB/s, which is not much anyway.

    really thanks! spinnerlys excellent explanation! interesting, now I understand,

    the only problem is that is hard... difference sometimes if is the same quality or almost the same quality (I mean in the final result file)

    you can recommend a preset for my goal?

    That's impossible. MPEG2 to H.264/MPEG4 is a lossy transcode, so you will always lose quality, regardless of the setting. You cannot make things smaller while retaining the same quality using lossy encoders. If you don't want to lose any quality, just rip the movie straight from the DVD as is. Frontrow supports viewing ripped DVD folders. Other players do too (Apple's DVD player, VLC, XBMC, etc).

    Now, losing quality doesn't mean bad. I ripped my DVDs and convert them to H.264 all the time. I simply use the Apple Universal preset, and the quality is great.

    True enough. However, there is the scientifically quantifiable loss of quality and the visually perceivable loss of quality. Using good settings, a HandBrake rip will produce a movie file with no (or extremely little) perceivable loss in picture quality. The space savings are well worth the time it takes, IMHO.

    from the handbrake faq:

    If you want the same thing as the dvd,then just rip it with a dvdripper but don't convert it and you'll get the exact same thing.

    thanks to all!! great responses, I understand now, I do test and is true... the rips looks amazing! like the original DVD... but now I have in mind if I want the true quality is better use mactheripper etc..

    thanks again!
