Very slow render, minimal CUP utilization

Using Premiere Pro 14.6.0 Build 51.

 

Some projects have extremely slow render times (3 hours to render a 9 minute video)

Other projects render at an expected speed, slightly faster than real time.

 

These are all extremely simple projects, just a few cuts, and a few text overlays.

 

The projects that render quickly utilize my CPU and GPU to a respectable percentage, somewhat higher than 50%.

 

The slow projects barely click over the CPU, utilization about 3% average. The is no hardware bottleneck that I can see in the task manager, disk utilization is practically zero. Nothing else is competing for resources. It seems like my computer has gone out for a coffee break. Rebooting doesn't help.

 

If it would help, I can provide more information regarding the footage that is slow to render. It is video that is submitted to me, so I have no control over how it is initially captured. Nothing seems unusual about it, it is generally shot on someones phone.

well, since it's "some" projects, think about what they have in common that others doesn't
