create proxy with mxf-clips and multichannel audio?

"Create proxies" with 8-channel audio footage (4096 x 2160 MXF AVC /H.264 XAVC codec, only 2 channels recorded) doesn't work. How can I solve this problem?

      Correct answer Trent Happel

      Which preset(s) did you try and what exactly is failing?

      I tried a few XAVC clips with 8 channel audio (only first two channels actually had audio) and Create Proxies worked for me using the default QuickTime ProRes and GoPro CineForm presets, as well as a custom DNxHD preset.

      Did you happen to use the H.264 preset and get an error in the Events panel? (The selected preset does not support the audio channel type of the clip). If so, this is expected, as H.264 export/transcode does not support 8 channel audio.

      Hello hpwagner,

       

      Note this warning from Adobe:

      "If your workflow relies on modifying the source clips using any of the following commands [Modify Audio Channels, Interpret Footage, Modify Timecode, Modify Captions], do not use proxies in Premiere Pro. Doing so will result in unexpected behavior."

      [page 55 of the Best Practices & Workflow Guide For Long Form and Episodic Post Production ]

      I have raised this issue in the forum here.

        Right click on your original file on the project window. Modify>Audio Channels

        DESELECT all the channels but keep the 1st and the 2nd channel activated. click OK and try again. Definitively you'll be fine with the proxy thing.

        I'm using adobe for years, they dont wanna fix their bugs til the world ends.

        Hey Iman (or anyone) 

        I found this thread because I tried the sugestion above but it didn't work. 

         

        I'm trying to create proxies in Premiere. I have MXF 8-channel audio footage from Sony FX5 and FS7. only one track of audion is needed. so mix down or delete all track except fiert is fine)

         

        I need to upload the proxies so I need to find a work around to get them into H264.

         

        I used MODIFY>AUDIO CHANNELS and tried unchecking channel, mono one channel,  unchecking all audio etc

        and still get error with H264.

         

        The only work around I can think of is to create ProRes intermediary files with audio mixed down then convert those.

        Is there an easier wasy?

        and if I follow this work flow (rather than creating proxies from Project window) will I be able to toggle between proxies?

         

        Thanks,

        Cary

          Not sure if this info is useful but I ran into the same technical brainstorm. What I did was in media encoder program is the switch from H264 to QuickTime in the "FORMAT" TAB and in the "PRESET" I used 1024x540 Apple Prores 422 Proxy. The camera I used was Sony FS5M2

              Thank you very much! I used a H.264 preset, but with the presets you recommended it works. Now I can enjoy it, because I was waiting since long for "proxy".

                Camera: SONY PXW-Z100, Footage: 4096 x 2160 mxf, XAVC, 8 channels as standard,  but only 2 recorded with SONY ECM-MS2 micro or built-in micro, recorded on XDQ-S-card and transferred to PC's HDD via SONY's content browser

                OK.

                Have you tried the 1024 x 540 Cineform proxy option under Ingest Settings?
