I get this error as in the title...what is happening with this latest version 26.3 when the same project was opened by previous versions without any problems.....and why does relinking take so long in the last version 26.3...I lose the will to work in Pp because of relinking...I can easily cook lunch during that time ;-) … My files are in this format and opened quite normally in previous versions.…

Hi @STUDIO29K,

Thank you for reporting this issue. The team understands how frustrating an occurrence like this can be.

This may be a Microsoft support issue when working with HEVC (H.265) codec. With a Mac, it is part of the operating system, however with a Windows PC an extension may need to be installed.

Please some additional links here that may be helpful:

Regarding the relinking, we will need more details to try to assist you:

Please let us know your video card driver version.
- We recommend updating to the most recent version; for NVIDIA users, we strongly recommend the Studio version of the driver.
When did the relinking issues begin, or is this the first time?
Does it affect new, empty projects?
Are you able to provide more details about the footage specs? (codec, resolution, import process, general workflow)
- Where is the footage being stored? Locally or on an external drive?
- Is the Premiere project file and the footage being saved in the same location?

Best,

Jonathan

1. Isn't the HEVC codec an integral part of Pp? Until version 26.3 there were no such problems...
2. Relinking... video driver, latest STUDIO driver 610.62... at least you don't have to remind us...
3. problems with relinking start from versions 26.2 - 26.2.2 and especially the last version 26.3... I forgot to tell you that during all the time of loading projects, i.e. relinking, the CPU goes up to 80% and when that icon in the upper right corner of Pp says that everything is loaded (which it is not)... the cpu stays at 50% for 15-20 minutes for sure... it never happened and then there is a return to 26.0.2, which loads the same projects in 20 seconds and which is the most stable for now...
4. All projects are on NVMe 2 and I can no longer tell you what my configuration is, you can find it in my previous posts...
5. HEVC codec problem only happens with v.26.3.
6. Pp is on one NVMe 2...projects on another NVMe 2, data and media cache on the third NVMe 2 and so on…

The first image that the HEVC codec is not present occurs when I load the files with the description in the second image... it is the HEVC 10bit 4:2:0 format from my Panasonic CX 350 cameras and that HEVC error is displayed only in v. 26.3... in others never... and versions below 26.3 load those files normally without reporting the lack of HEVC codec

finally, here is my configuration so you don't bother me anymore:

RTX 3090TI 24GB
Ryzen 9 3950X
64GB memory
1NVMe M.2 for Os
1NVMe M.2 for video
1NVMe M.2 for cache....ect

Pp 26.0.2 rules... and give us back the Premiere Pro name...

Hi @STUDIO29K,

Regarding the HEVC codec, can you please try the following:

Logging out of your Creative Cloud and logging back in.
- Perhaps there is a sync error that requires a full log-out and reauthentication.
Are you logged-in across multiple devices?

Best,

Jonathan
