what is happening to my "offline" media here?

Hi everyone. I'm following this thread since I got my M3 Pro in December. Same probleme here. Same filetypes as mentioned above.

Some thumbnails show "Media Offline" randomly in the project and render causes crashes. The only "solution" is to disable the hardware encoder which is an absolute no-go for me due to reduced performance.

If I can provide anything that makes investigating this problem easier for BM I'll do so!

I'd suggest trying the 19 beta, and if it still crashes on render, post a log to the beta subforum.
Posting a log is explained in the FAQs.

To others with an M3, but no Sony: please contact me if you need a test clip. I have a Sony A7IV, but no M3.

As I am in the middle of a big documentary that will last for the next 2 months (minimum) I can not update Resolve. But I will do so as soon as this project is finished.
