    Interpred Footage doesn't resample add. audio tracks

    nw42 Level 2

      Hi,

       

      I've a serious issue with the "Interpred Footage" funktion in Premiere. If you use it with footage containing more than one audio track - all additional audio tracks arn't resampled after project is reloaded or sent to AME - resulting in out of sync audio.

       

      Has anyone similar problems or a workaround for this?

          Exactly what changes are you making in the Interpret Footage dialog?

            Hi Jim,

             

            I change the frame rate e.g. from 25 to 24fps - so the duration of the image changes and the audio has to be stretched accordingly.

             

            After first change of the frame rate via "Interpred Footage" everything is fine - and all audio tracks (6 multichannel for 5.1 audio) are stretched in the right way.

             

            But if the Premiere project is saved and reloaded or send to AME (what results in saving and reloading) only the first audio track is streched and all additional audio tracks fall back to their original run lenght. So audio get's out of sync and rendered files become corrupted.

              Yeah, that does sound like it might be a bug.  Maybe try a direct Export, instead of Queuing to AME.  Any difference?

                Hi Jim,

                 

                direct export is working as long as the project wasn't saved and reloaded. But you can't work efficient if you can't save a project or use AME... ;-)

                 

                Until now we have to reset every changed footage framerate - set it again and then export - to be save... not the best workflow... :-(

                  True, but your work is somewhat off the beaten path.  Normally you'd shoot at the correct frame rate.  Most folks changing speed with Interpret Footage are creating slow motion and won't be using the audio anyway.

                   

                  I'd report it to Adobe, just don't expect a fix any time soon.

                    Hi Jim,

                     

                    thanks... ;-)

                     

                    anyhow I think our usecase is typical and important:

                     

                    We use the "Interpred Footage" change framerate option regulary to conform mastered clips on the fly to different video standards.

                     

                    For example:

                     

                    A) We have a 24p 2K Digital Cinema Distribution Master DCDM

                     

                    Our client asks for:

                     

                    - 25p Press DVD PAL

                    - 1080p25 EPK material

                     

                    so there is no time for complex conforming work in different applications... import into 25p sequence - insert Overlays - burn in TC - create stereo submix from 5.1 -  export as PAL wide....

                     

                    Or we get 23.976fps footage and have to conform it to 24p for Digital Cinema Package delivery...

                     

                    Therer are complex workflows and multiple export targets involved if you get 23.976 and have to deliver 24p and 25p for WEB, TV, Home Cinema & Cinema

                     

                    Only the "primary quality targets" getting a extra audio mix from the recording studio or HQ confroming via Izotope... If it's only for WEB or the subtiteling company - audio is streched on the fly...

                     

                    So - ok we have an extreme usecase - but every filmmaker could be asked for a 25p image reference for DVD subtiteling of his 24p cinema master...

                     

                    it's not only for slomo any more ;-)
