Forums Avid Media Composer LUT keeps “falling off” my transcodes?

  • LUT keeps “falling off” my transcodes?

    This is driving me nuts. I’m transcoding Amira UHD footage to DNxHR LB with an embedded LUT. A lot of the time the LUT is applied (I have “apply color encoding” checked) but then, mid transcode on a bunch of clips, it disappears and is no longer applied to footage. Half the resultant clips have the LUT applied, but the last half don’t. So, I have to transcode one clip at a time and check to see if the LUT actually got applied. Many times it doesn’t. So, I try it again….and then it works. Then it works for a few transcodes and disappears! I’ve tried deleting Media Composer’s and the project’s settings and using new user settings. Nothing is fixing this disappearing LUT business. Has this happened to anyone else? I’m basically having to babysit my transcodes.

    I tried everything to make this work. I even upgraded to the very latest version, but nothing stopped the mysterious disappearing LUT….except this….

    I selected a bunch of shots and loaded then ALL into the source viewer. Then the LUT would consistently stay during transcode! I think Avid needed to open the clip to see the embedded LUT (or something like that – who knows?t). Otherwise, it would just skip adding the LUT at random.

    When using Amira embedded LUTs you have to transcode with baked in. Avid does not support Amira LUT information as metdata once trancoded.

    Thanks, Michael. The LUT would fall off during the transcode. It’s a bug of some sort, I think. The only solution was to load all the clips to transcode into the source monitor and then start the transcode. Then the embedded LUT would be baked in on the transcode.

    Very strange indeed. Glad you found a workaround.
