Premiere Pro 24.1 Substitution Recursion Errors on Sony XON - LT Footage

[Brandy35558378p7ve]

I'm starting a new project that was shot 6K Sony XON-LT mxf. Upon importing the files into my project I was immediately hit with the frame substitution recursion error box. Also, all of my videos are completely black. I deleted my media cache, reset my plugin cache, and disabled 3rd party plugins. I saw on a different post that someone recommended downloading the new Premiere Pro 24.6 Beta as a solve, but I'm only seeing v 24.5 as an option in my creative cloud updates. Luckily, I am at the very beginning of my project so I could transcode the files into ProRes via Davinci if need be. It seems like quite a few people have run into issues with the MXF files in Premiere and I was curious if anyone had found a solve for this issue yet? I'm editing in Premiere Pro 24.1 & on a Macbook Pro M1 Chip with 32gb RAM.

Hi @Brandy35558378p7ve - XOCN-LT wasn't supported until Premiere version 24.2. Can you try updating to 24.5 and let us know if that helps your issue.  You can also download the Premiere Pro beta 24.6 in the creative cloud app under Beta Apps.

Thanks Jamie! That worked and allowed me to import the footage properly into my project. However, I went to go make proxies & media encoder was unable generate them properly. When I looked at the encoding error log I was shown 2 different reasons for error. 1) Frame substitution recursion attempt 2) Could not read from the source. Please check if it has moved or been deleted.

Any idea why this happened? The media has not been moved or deleted. I'm making proxies b/c some of my individual files on are the beefier side, as big as 24gb per file.

Hi @Brandy35558378p7ve - Can you make sure Media encoder is on the latest as well. 24.5 or 24.6.

Yep, that worked.

Thank you!
