Title: Getting the Best Video Quality When Shrinking a Blu-ray onto a Blank Bd25 Disc

  • Getting the Best Video Quality When Shrinking a
    Blu-ray onto a Blank Bd25 Disc
  • It is a deep tooted concept that whenever
    compression is needed in the process of backing
    up a video, then there must be a certain degree
    of loss on video quality. Well, this can be true
    in the past, but no longer be true with todays
    technology, like the introduction of the HEVC
    encoding which is able to keep the file size down
    50 but double the video quality, or another
    technique from DVDFab which is what this article
    is mainly about, a solution to remove unwanted
    audio tracks when backing up a Blu-ray disc so
    that users can significantly improve the video
    quality but still cut down the final file size.
  • What users get with this technology in the
    end is a perfect Blu-ray backup with his wanted
    audio in his native language and almost doubly
    improved video quality. How can this be true?
    Yes, it is true. This new technology is so far
    only available from DVDFab, to be more specific,
    its Blu-ray copy software, and only under the
    Full Disc mode when users want to compress an
    entire Blu-ray disc down to BD 25 size, in order
    to save money buying the pricey blank BD50 discs,
    or to save free space on their HDDs or external
    HDDs to accommodate more data.

  • The centerpiece of the solution lies in the
    fact that it allows users to remove all the
    unnecessary audio tracks, so that there is much
    free space on the blank BD 25 disc to hold much
    video data, which means, less compression will be
    made on the video, and small compression rate
    means better video quality. As to why removing
    the audio tracks, instead of other things like
    subtitles, there are some primary reasons, the
    1st reason is that on many Blu-ray discs nowadays
    there are usually a couple of audio tracks in
    different languages attached to the feature
    length movie title, which when making backups,
    users dont necessarily need all of them, they
    just need the audio track of his native language
    and the 2nd reason is that audio tracks,
    especially those high fidelity audios like DTS HD
    Master 7.1/5.1 sound, always take up a lot of
    space due to its huge size. So it would be very
    necessary to those who have a tight budgets on
    blank BD media to save up much free space on each
    blank BD disc they have just to make the most out
    of it, and that is why this solution is all
    about.
  • Just take an easy example, on the original
    Blu-ray disc of Despicable Me, there are 4 audio
    tracks attached to the main movie title,
    including a DTS HD Master 5.1 track which is in
    English, a DTS 5.1 audio in Spanish, another DTS
    5.1 audio in French, and a secondary AC3/2 audio
    which is the directors comment. To a movie lover
    living in the US, he does not need all the audio
    tracks except for the English one, so while
    making backup copies, he can choose to keep only
    the DTS HD Master 5.1 audio and ditch all the
    others and to a guy from France, he might only
    need the DTS 5.1 audio in Frenchthe same thing
    happens to the other titles on that disc.

  • As of now, DVDFab is the 1st one on the
    market to offer such a solution, and it will soon
    be available in the next official release. Early
    birds who want to bite the fresh cake can now go
    to the forum and download the Beta version
    9.2.4.3, others who have no interest in beta
    testing can wait a little bit longer, as the next
    official release is already on the way.
  • Attached below is a compassion picture
    between two full disc backups shrank down to BD25
    size, with the one in the left keeping all the
    audio tracks, and the one in the right keeping
    only the user selected audios. The nominal bit
    rate of the video increases to 11.7 Mbps, from
    the previous 6.918 Mbps, a significant
    improvement on the video quality.
