Strange Picture Codec Issues
 
Dear All,


Our picture department upgraded their systems using Os Big Sur and media composer 2021.6 on Intel iMacs. We unfortunately are on older systems using Os Sierra and PT HDX 2019.6 on Older Mac Pro Towers (Cheese Graters).



We have always used Avid DNx HD 36 QuickTime files without issues. However, now the picture files coming in are becoming extremely problematic. Either we will get a green screen, they will not play or the video engine will not stop playing. I'm told they are exporting DNx LB files.


Any thoughts as to why this may be happening?


PT HDX 2
Os Sierra
48GB Ram.

DNxHD LB is practically the same as 36 I believe but it is a newer version of the codec. Have you tried installing the latest Avid codecs on your machines? You should be able to download from Avid. I haven't used my cheese grater in about a year and a half but I'm pretty sure I was using LB.

I have not. I will go on the other site and look for the newest Avid codec installer.

Hopefully it will install on Os Sierra and not be a metal graphics card(Mojave and above) type of installer.

Just in case others are having this issue, I updated the Avid Codecs with Installer version 2.76 and now the pictures are playing OK.

Good to know.
We've been receiving video files from MC editors that won't play on anything but Resolve (albeit with corrupt audio). Including H264 files. The error is to do with ipcm codec.
Anybody know what to tell the editors not to click to create this unusable type of file?

Hi Vedat, If you like contact me via same email or cellphone number to discuss setting up some MC export settings tests.

I have the time and several versions of MC including the current one here.

We generally ask for Avid DNx HD 36 or newer DNx LB either .mov or MXF with window burn.

Be aware however, depending on what version of ProTools you're running, you may not be able to import the audio from the MXF version but you will on the .mov file.
