  Can I replace audio in OP1a MXF without retranscoding the video?

  I want to import an MXF OP1a and replace the audio tracks without changing the video at all. Is there a way to do this without re-encoding the video?

  You want to completely replace the audio tracks? Just pull video-only onto the timeline.

  System:
  Dell Precision T7600 (x2)
  Win 7 64-bit
  32GB RAM
  Adobe CC 2017.1 (as of 8/2017)
  256GB SSD system drive
  4 internal media drives RAID 5
  Typically cutting short form from UHD MP4, HD MP4, and HD P2 MXF.

  I want to avoid retranscoding the video (XDCAM MPEG-2).

  No–if you’re changing anything about the file, that means re-rendering. Just bring the clip in, replace the audio, and export to a lossless format like ProRes 422.

  Ok, then. Much appreciated!

  Actually, I found an export option that just rewraps the file. So, it seems like you were incorrect?

  I don’t know if it’s possible with Premiere, but it is definitly possible.
  If you think you have found a way, just see how fast it is. If it’s lightning fast, the video is copied instead of transcoded.

  I think you just have to enable the smart rendering for OP1a MXF !
