    [Any to mobile] Where is the necessary option VBR ??

    When converting a DVD or a blu-ray to mobile (m4v, avi, mkv...), to get a correct quality, we must use a vbr method that any software does since years and years...

    But in DVDfab, I can't find the option !

    2 pass encoding made a sad cbr encoding, so big files with very poor quality...

    So... Dis I miss something ? or do I have to trash my license and use freewares instead ?

    Thanks

    Absolutely not, you don't have to use VBR. This statement of an ignorant person.

    that any software does since years and years...
    Incorrect. Not any software have VBR option

    2 pass encoding made a sad cbr encoding, so big files with very poor quality...
    Try single pass

    So... Dis I miss something ?
    Yes, you did... a lot.

    or do I have to trash my license and use freewares instead ?
    That's up to you. I can give you a hug though

      Your post have nothing to do with "Third party products" subforum, I'm moving it to appropriate subforum.

        The new profile system in v8.0.9.8 may allow support for VBR settings, either now or in the future for some of the codecs. I think you will find that the processing rate will be slower for negligible benefit.

          Advantages and disadvantages of VBR

          The advantages of VBR are that it produces a better quality-to-space ratio compared to a CBR file of the same data. The bits available are used more flexibly to encode the sound or video data more accurately, with fewer bits used in less demanding passages and more bits used in difficult-to-encode passages.[2][4]
          The disadvantages are that it may take more time to encode, as the process is more complex, and that some hardware might not be compatible with VBR files.[2] VBR may also pose problems when streaming over a dial-up or broadband Internet connection, because the instantaneous bitrate, if unconstrained, may rise above the maximum data transfer speed of the web connection. These problems can be avoided by specifying a maximum instantaneous bitrate during the encoding process.

            Thanks, I understand how it works, I am just skeptical of the benefits for most purposes for which DVDFab would be used. If you prefer it, I hope they will support it as an option for both Rippers.

              As I make encoding with source since 12 years (mpeg 1 for VCD with premiere), then divX, dvd, HD-ready and full hd movies with many software, I encourage the VBR option as it brings very better results when the bitrate is low.

              When the bitrate is higher than 4000 for HD-ready and 8000 for full-HD, it does not really change (but professional uses it for any dvd and blu-ray), so I thing it stays the best solution.

              For mobile movies, vbr is necessary to get good results when image moves (action movies) a lot, or when you have moving textures as water-surface.

                I agree with you too, Signals and am skeptical also.

                Generally, media players handle CBR encoding better, to the extent that some new Sony POS's will not even play VBR!!

                I think that the level of complexity that this user wants to delve into is not the market where Fab is positioned. I think he needs to use a high-end professional encoding/transcoding solution to achieve his goals.

                  Who is ignorant about VBR benefit?
