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.

Hello to everyone. If you experience this problem - you are not alone

My situation is totally the same - random "media offline" no matter which hard drive and its file system. Errors during export in random moments.
MacBook with m3 pro chip
Using files from Panasonic S1H - 4k 422 10 bit H.264 25fps Vlog

19 beta didn't solve anything. But I can add that FullHD timelines in the new version of DaVinci Resolve during export have less chance to get the "decode error"

I hope this problem will be fixed soon. Switched from Premiere Pro and DaVinci Resolve became extremely important for me. This small bug sometimes causes too much discomfort. Can't wait when it's fixed.
It is strange that exactly MacBooks with m3 pro chip have this problem

While you ingest your footage and transcode a new high quality ProRes “original” suitable for finishing. Then swap out the source original for the high quality ProRes in media manager.

Basically that removes all issues related to h.264 or h.265 which are small heavily compressed source media unsuitable for editing. But the cost is drive space. And some prep time. The colour page, and fusion, and delivery will all use your designated high quality source. So unless you do the juggle I suggest it will try to use the h.264, with less than reliable results due to timecode, and decompression issues.

Hello, I am new to video-editing and haven't even started learning DaVinci Resolve yet.

Are you saying that converting H.264 and H.265 files to ProRes will completely fix this problem of "offline media" for M3 Pro and M3 Max users?
