    Bitrate

    wayne greensill Community Member

      Hi there,

       

      I am just about to build my first Blu-Ray Disc and need a little help with the Bitrate settings.

       

      I have sent my project from Premiere CS5.2 through to Encore via the send to Encore link. Gone through all the stages of naming project etc then it comes to the project settings window. Do I leave it at the default transcode settings whis is set at the following:-

       

      Codec: MPEG2; Dimensions:1440x1080; Frame Rate:25; Fields: Upper Field First

      Maximum Audio/Video Bitrate: 15.0Mbps

       

      My Timeline length is 3hr 16mins, a wedding project.

       

      So my question is, do I need to up the bitrate or just leave it at the default transcode setings letting Encore Automatically Transcode. I normally let this happen when I create Dvd's but unsure if I can do the same for Blu-Ray?

       

      I would appreciate it if anyone can help.

       

      Regards

      Wayne

          Hi Wayne,

           

          I would change from MPEG-2 to H.264, especially with the longer run time, since H.264 will provide a higher quality as it is more efficient at lower bitrates.

           

          Thanks

            Hi Jeff,

             

            Thank you for your reply.

             

            I have a problem with the sound quality it sounds a little distorted. I have raised the bitrate for the audio to 448kbps but it still sounds pretty poor.

             

            Would I be best to carry on using the Dolby Codec or PCM? I only have 2channels of audio.

             

            Look forward in hearing from you.

              Hi Wayne,

               

              For DVD burning in Encore, the default rate for Dolby is 192kbps, and I use 224 sometimes but have never thought the audio sounded weak. Did you actually burn a disc, or are you previewing sound inside Encore? PCM is basically uncompressed and takes up a LOT of space, probably close to 2GB for your long program.

                Hi Jeff,

                 

                It is a Blu Ray project I'm having problems with, within Encore. Yes I have finally managed to burn the project onto Blu Ray discs but the audio just seems to loud. Sounds fine when played through Encore and Premiere. This is why I'm a little unsure whether I have the correct settings for the Audio?

                 

                I had trouble sending the project from Premiere to Encore Via dynamic link. During the build in Encore was getting all kinds of error codes so decided to export through AME. This is where I'm a little unsure whether I have to correct settings.

                 

                I did use H.264 as it was a large project but not sure about the correct procedure for the audio?

                 

                Just to let you know the Versions I am using is Premiere CS5.52 with Encore 5.1 and Matrox MX02 Mini with Max.

                 

                Thank you

                  If you choose an "H.264 for Blu-ray" preset in AME, it should export the audio as a .wav file (uncompressed). You take that into Encore and it should by default transcode the audio to Dolby, so pretty hard to mess it up, it just works.
