A rendered video that takes 7 minutes at HD is taking 16 hours at UHD. Same settings. Is this normal? It seems like a pretty big jump for just 4x resolution. Am I doing something wrong maybe?

Thanks,

I had the same problems while rendering a 4k image. It took 30mins, while rendering a 8k images took 8 Hours.

Quick question, do you have 'Tile rendering' turned on/activated?

If so, this is probably damaging your export times. This feature should only be used for 16K+ resolution videos.

Turning it off, reduces the export time.

Cheers,

Francesco

Ha!!! That's it!!! This is exactly the type of thing I was hoping for! You are the man Francesco! I thought that turning on tile render would maybe use more CPUs like bucket rendering in most 3D programs. Of course this is different than that. Much appreciated, once again! I really appreciate how you worked me through this. A+ service!
