Recoding for Blueray

I;m trying to put multiple videos on one blueray. I've used the Recoder to shrink them from around 7gb to 2 gb. BUT WHY when i put them into NERO VIDEO does it expand them to 25 GB?!? I'ts killing me. Please help

  • Hi, OK. The minimum bit rate in Nero Vide for Blu-Ray is 14 MBit/s. This sums up to more than 6GB per hour. So a 25 GB Blu-Ray will hold around 4 hours at this low bitrate regardless of the file size the source files have.

  • Zach,

    Clearly, the "Keep Source Quality" setting is a bit confusing! If you position your cursor over the setting the tool tip appears:



    So, it actually maximizes the output bitrate if the source video does not have a compatible format!

    For example, if the source file is a low bitrate MPEG-4, part 2 video, it is not compatible with Blu-ray and is re-encoded at a high bitrate:



    On the other hand, if the source file is a low bitrate MPEG-4, part 10 (AVC or H.264) video, it is compatible and is encoded at a low bitrate:



    Now, you may notice that the result bitrate is shown as high but the file size is compatible with a low bitrate.

    Hopefully, Since5.5 (Employee) will return with some clarification.

  • Thank you for the replies! I'm still new to encoding and video conversions so I'm sorry in advance if I ask he same thing.

    So what if, I have an MKV file that was 7.8 GB and i use NERO Encoder to make it and MPEG-4 with a max size of 2GB. Outside the program I can watch it and it works with perfect quality. I try to put it inside the NERO Video app under Blue Ray disc and the file expands to 22GB. And you're saying its because the bitrate?

    Also I'm having trouble adding subtitles. I have the SRT file but in what part of NERO do i add them? On the Encoder i have the option too but it is greyed out, and un-selectable.

  • Zach,

    As I understand it, Nero doesn't do SRT files.

    And, yes, I think you should be able to do what you are trying to do. However, it would help to know more about your source file to determine its 'compatilbility'. The pictures that I posted above showing the resolution, bitrate, size, etc. are obtained by importing the source file into the Nero Video editor, double-clicking on it, and then selecting the Metadata tab. Please post that information.

    Also, as you can see above, knowing exactly what will happen is difficult since there is no documentation, no examples, etc.

  • Zach,

    When I saw that your resolution was near but not 1280x720, I thought choosing 1280x720 in the Recode options would help but a little test I did makes me doubt it. So, since I don't know the exact requirements I'm thinking you may need the explanation from Nero that I referred to above. I redid your picture for others that may have an idea.

  • Zach,

    I gave it another try today. I started with a 2 minute 1920x1080 video and used Nero Recode to convert it to 1280x720 at various bitrates and frame rates. I couldn't find any combination that was 'compatible' (i.e. SmartEncodeable) with a 1280x720 Blu-ray in Nero Video. Recoding it to a low bitrate 1920x1080 was 'compatible' (i.e. SmartEncodeable). However, as noted above, the bitrate of the source file is incorrect shown in Nero Video. Here's data for the same file as displayed in Nero Video on the left and another frequently used analysis tool, MediaInfo:



    Perhaps Since5.5 (Employee) will help (or get an expert to help). But, the criteria that a video must possess to be considered SmartEncpodeable have been requested many, many times in this and the previous forum to no avail.

    • haha Omega Tester you have been a great help and you have done more than I expected. But I think i have figured it out. I'm not good at the pictures so hopefully i can convey what ive done.

      First i uploaded the original file into XMedia and for some reason i had to correct the resolution to the 1280 X 720. Then I selected the output .m2ts. It was originally 6.5 GB, then after XMedia it became 3.7GB. THEN i used the Nero Encoder to shrink it down to a 2GB .MP4.

      (I was able to encode the Subtitles with the original Japanese audio in XMedia)

      And when i uploaded to NERO Video it maintained it's 2gb size.

      Im ecstatic Omega Tester.

      Ive seen many other posts with your comments on them, you are doing a great job helping people thank you.
    • Zach,

      Thanks. I just pop in here occasionally if the topic interests me. I can't say I understand how what you did worked, but if you're happy ... I didn't know XMedia Recode would encode SRT files. I'll have to get some and give it a try.

  • Well I'm not good at doing the screen shots but you deserve to see, I'm not sure how it worked I just know it did.

    So I start with MKVToolNix GUI, to MUX the .srt file with the . mkv video so that it is hard coded but doesnt change any of the video specs.



    Then when its finished I upload the finished file into XMedia. and these are the specs I have to change or add.

    VIDEO

    AUDIO

    SUBTITLES



    Then for the Subtitles you have to make sure to click the transfer them by hitting this button.



    then i have to adjust the size and change the aspect ratio to 16:9



    Then recode in Nero and change the maximum size to 2gb and it works.

  • Nero Recode has dedicated output profiles that will ensure that encoded files are 100% SmartEncoding compatible.
