    Conform Avid DNxHD36 to DNxHD175

    I shot footage on RED EPIC and my DIT guy transcoded the R3D files to Avid DNxHD36 using Da Vinci Resolve (with some color-correction in the trans-coded files). I used these DNxHD36 files to create the offline Edit on my Windows PC Avid 6.0.1. I have finished the edit now and have several sequences ready to be exported (+ some have VFX needs).  In order to help me out, my DIT guy color-corrected the R3D files once more and transcoded them to Avid DNxHD175. So, now I have a whole new set of color-corrected, transcoded MXF files. I want to be able to replace/ relink/swap my DNxHD36 clips with the new DNxHD175 clips (preferably only for the clips that I used in the final sequences). My original DNxHD36 clips are located under "C:\Avid MediaFiles\MXF\", where as my new DNxHD175 clips are located under an external drive "K:\Avid MediaFiles\MXF\". I am able to use the Media Tool to point to the K: drive and see the DNx175 clips. 

    But, I cant seem to figure out how to re-link my sequences to the NEW MXF files. I tried to relink the clips in one test sequence by deleting the reference DNx36 clips from its bin, and using the re-link option to point it to the new MXF DNx175 clips, but the media stayed offline.  What is the best way of doing this? I am worried that I would mess up my file links and lose my edits.

    In theory if the new MXF files have exactly the same metadata as the original one. Just hidding the DNX36 files should cause the sequences to link to the DNX175 media. But the relink command should do that as well.

    If the sequence won't link then it's possible the new MXF media isn't exactly right.

    Two things to check for are matching timecode and reel name. I've has success relinking by manually changing the reel name to match up, when there was no reel name to start with.

    If the metadata of the 175 has changed then you can try and add tape numbers to the clips of 36 and 175 files that match, which then will help you with relink using the tape option.

    Thanks to all. Changing the Tape Name works! 

    I was doing some other things incorrectly as well as I had insufficient understanding of how Avid Databases work inside the MXF Folders. But, now I understand, and everything seems to be working. 

    Yes
