    BD Ripper (3D Plus) MP4 bitrate not used

    Hello,

    I'm running DVDFab 8.1.1.2. I'm trying to convert a back collection of Blu-rays to MP4 so I can stream them to my TV. I'm using h264 with AC3 codec.
    I use a video bitrate of ~24Mbps and 5.1 audio of 640kbps. Most videos convert without problem. However, some videos don't convert at 24Mbps, they convert at anything between 10 - 30Mbps and is typically the same each time you do it. This results in some movies having considerable artefacts.
    Is there any way that when selecting the bitrate you can force DVDfab to encode at the bitrate, either as CBR or a target average?

    Thanks

    You getting artifacts not because bitrate is too low, but because bitrate is too big. 24Mbps is really high for streaming. You better make sure your network can handle such hign bitrate. I would recommend to re-code your content to 10-12Mbps using DVDFab - you wouldn't dee the difference, except artifacts will go away.

      Many thanks for your reply.
      I've done quite a lot of testing with the streaming, and I can stream at 30Mbps before the video starts to judder at the other end. If I use the playstation and my gigabit network, I can push this as high as DVDFab can go (50Mbps I found).

      I appreciate that I could encode at a lower bitrate, but I reckon I can definitely see the difference in the picture quality.

      Either way, I would still like to know how to make DVDFab encode at the value set.

        Hi Benzas
        Along with my friend IPopov50's advise, you can try the newest version of Fab found here http://forum.dvdfab.com/showthread.php?t=14578 and see if you still have problems.
        You can also try turning of Cuda and using the software option.
        Open Fab click the Click the Green √ at top right corner of the DVDFab screen, and open Common Settings > General >A/V Codec, put a check in Disable all GPU codes and make sure they are set to Software, restart Fab and try again.

          Hi CBR929

          Thanks for the suggestion. I installed the latest version and tried converting (trying expendables at the moment) using both intel quick sync and software only (I don't have an Nvidia card for Cuda, only AMD).
          However, neither worked, it still outputs a file with a bitrate of 13.9Mbps. Not too bad I know, but not the 24Mbps I'm setting in the video settings.

          Any other suggestions?
          I've attached the profile I'm using in case that helps at all (converted to txt file as xml is too big for site limit).

          many thanks in advance.

            I also tried increasing the bitrate setting in the video settings to see if the output bitrate increased proportionally, but no luck.

            Does anyone else have a profile I might be able to use which puts h.264 and ac3 into an MP4 container?

            Thanks

              Hi

              You can use the Profile Editor to create a new profile mp4-h264-AC3 with differnt presets. You can get the Profile Editor from the "DVDFab DVD Ripper / Blu-ray Ripper" section of the form, it's a sticky at the top. Don't know if it'll help with your issue though.

                Many thanks, I'll give it a try. I already had it downloaded but haven't used it yet as I just modified existing ones in notepad.

                Will post if successful.

                  UPDATE:

                  It seems that two pass encoding simply doesn't obey the bitrate you set in MP4. single pass works fine though, it's just a shame it doesn't quite generate as high a quality output.
