    Preparing Music Video for Broadcast in Premiere and Encore?

    OWMMusic427

      I am trying to prepare a music video for broadcast in Premiere Pro. However, the specs require audio (Ch. 1-2 stereo, Ch. 3 mono Ch. 4 mono). I can't find a way to do this in Premiere Pro. I seem to be able to do this in Encore - I can create four audio tracks.

       

      Problems so far:

       

      1. I can only import the stereo wav file onto track 1, and have to import it again on track 2. The stereo mix isn't spread across both tracks Left/Right. Will the stereo mix appear on the correct tracks when delivered for broadcast?

       

      2. I need to export the video as an mpeg 2 on my hard drive - not actually burn to disc. Can I export an mpeg 2 video file without burning to disc?

          Four audio tracks in Encore?  How are you going to deliver your master?

           

          You might have to export separate tracks, or use Audition (if you have it).  You can export a mono AIF or WAV from Pr from your stereo mix.

           

          Yes, you can make an MPEG2 without buring a disk.

           

          Provide more info please.  I don't follow your issue on your Problem 1.

            I am delivering the master as an mpeg 2, uploaded by FTP.

             

            Here are the audio specs:

             

            Stereo Left and Right audio signals must appear on channel 1 and 2 respectively

            Dolby ProLogic matrixed audio (Lt /Rt) may be substituted for Stereo audio on channel 1 and 2 if desired

            Monaural audio may be substituted for Stereo on channels 1 and 2, but must appear on both channels and must be in-phase.

            Secondary Audio Program (SAP) if available, must appear on Channel 3, otherwise a mono mix of Channels 1 and 2 should appear on Channel 3.

            Descriptive Video Service (DVS) audio, if available, must appear on Channel 3 if delivered in lieu of SAP audio

            DVS must appear on Channel 4 if delivered in addition to SAP audio, otherwise a mono mix of channels 1 and 2 should appear on channel 4.

             

            So basically, I need a Left and Right stereo on Ch. 1 and 2. And mono on 3 and 4, because I don't have SAP or DVS content.

             

            I can create 4 audio tracks in Encore, then I import my stereo wav file and mono wav file. But when I drag the stereo wav file onto audio track 1, both channels of the stereo wav file are on track 1. I read in Encore's help files that (assuming this would be going to DVD and not an mpeg on my hard drive) only one audio track can play at a time. Each individual audio track appears to be stereo, but I don't know how they would each correspond with the requirement for Ch. 1 to be stereo left and Ch. 2 to be stereo right. As of right now, it appears that track 1 is both left and right, and I can import the same stereo wav file on track 2 seperately with both left and right audio.

             

            The specs I'm trying to meet are Viacom/MTV which is a major outlet for music video content, so I'm assuming their requirements are reasonable enough.

             

            As for making an MPEG2 from Encore without burning a disc, here is the format:

             

            Container: MXF OP1a (SMPTE 378M)

            Resolution: 1920x1080i (interlaced) 16x9 aspect ratio

            Encoding: MPEG2, High Profile@ High Level 4:2:2, 50Mbps Long GOP, CBR, 29.97 frames per second (59.94 fields per second)

            Audio: Uncompressed 2-, 4-, 12- or 16-channel audio, 24bit @48khz, BWF (SMPTE 382M). All audio channels must be contained within 1 MXF track.

             

            Not sure how to export from Encore - only options I am seeing involve burning to DVD or Blu-Ray.

             

            I really appreciate your help thus far!

              You can't export a 4 channel mix from Premiere Pro.  You're only options are mono, stereo or 5.1.  To get what you need here, you'll have to export out three separate audio tracks - 1 stereo, and two mono.  You'll then need to use a separate non-Adobe program to mux those audio files with the video file to create just one 4 track A/V file.

               

              You will not use Encore at all for your purposes.

                Use AME  File > Export > Format = MPEG2 >Profile 4:2:2, Level=high.  Set your rate, etc.

                  Any recommendations for a separate program? I really can't afford to spend as much as I just spent on CS5. I was hoping it would do all that I needed.

                    I'll try this, although it may not matter now if Adobe can't output audio in the format I need. Thanks though - I'll take a look just for my own curiosity.

                      You can use AME to make your MPEG2, as has been suggested.  You can also export that right out of Pr.

                       

                      The 4-track BWF MXF is the one that stumps me. 

                       

                      You can export a stereo AIF from Pr.  You can export a mono AIF of your mix (be sure to reduce the volume by -3 to compensate for the increase in volume you'll get by summing two tracks into one).  But, I don't know how you'd get those into a 4-track BWF (Broadcast WAV File, which is a WAV with metadata or time-code) MXF.  I think you will need some other app for that.  I found MXF Muxer by Googling.  Maybe that will work.  Maybe not.

                       

                      If you have a contact at MTV, why don't you ping them and ask for some assistance.

                        Sorry, no.  I've never had to do this myself.

                         

                        Might be time to start Googling.
