Exporting time tripled and weird GPU usage

Question

Hello everyone, recently my export time has tripled. I'm exporting to an MSI M470 M.2 SSD. I export videos of up to 30 minutes recorded with a Sony a6400 camera, XAVC S 4K 30 FPS, 100Mbps. Previously, exporting 30-minute videos only took me 10 minutes, but now it has extended to 30 minutes.

I've scanned the PC with HitmanPro and Windows Defender for viruses but found nothing. I've updated the drivers for my graphics card (RTX 3080), but the problem persists.

I changed the cache drive in Premiere to a faster one, but the problem remains.
I have deleted the cache
I have reinstalled Premiere Pro

I just do cuts and ad cross-dissolve on every cut on timeline

Settings: Match source - Adaptive High Bitrate
Video H264 3840x2160 30 fps Nvidia Codec

My system specs are:

CPU: Ryzen 9 5900X

GPU: RTX 3080

RAM: 32GB 3600MHz

All drives are SSDs - 1 SATA, 2 M.2, and they have DRAM/cache.

If anyone could share possible solutions, I would greatly appreciate it.

Thank you!

Hey Angie,Sorry for the issue. Could you share more details on the screenshots you've shared? Export time can be project-specific. Exporting an H.264 source file will consume more time than edit-friendly intermediate codecs like Quicktime Prores 422. You can try creating custom Ingest Settings (File > Project Settings > Set Action to Transcode). This can improve the editing experience and export time for your project. GPU usage is also expected to not be constant throughout the duration of the export. If you're using any effects on your project, they might or might not be hardware accelerated, which can also affect the export duration. Hope this helps! Post moved to DiscussionsThanks,Ishan
