Premiere Pro can not properly read files from the Panasonic GH5.

Hi Hjalmar Molin,

Sorry for the issue. It is a known issue with Premiere Pro. We are working on a fix.

Update to new version and keep previous version option missing

Thanks,

Vidya

There are numerous threads on this forum about the GH5 import issues. Many have found it possible to transcode in AME, although with the 2017.2 update a couple days ago, some are finding even AME doesn't take the GH5 files. So you can look around for other's experiences.

While transcoding at first seems a bit of a pain ... the GH5 media is long-GOP highly compressed. Long-GOP compression means there's only a complete frame every so many frames, typically 10-15, and for all in-between frames, the CPU needs to de-compress & store in RAM the one complete frame, call up the data-set of pixels that change for the next frame, then recall the complete frame from RAM, compute the differences, store the new frame in RAM, call up the data-set for the next frame, compute, store ... rinse & repeat.

It is incredibly CPU/RAM cores/threads intensive with 8-bit 1080 media. By the time you're running 10-bit 4k media in this fashion, the data load on the computer subsystems is through the roof. It may be great for the camera to get the media compressed onto disc, but horrid for the computer to work with.

Hence, transcoding into a full intraframe such as Cineform 10-bit YUV or DNxHR for editing can be a vastly better experience. Even then, transcoding then having the auto-proxies is probably wise on most computers.
