Neat Video Question (RAM Related)

It's important to understand that Premiere Pro and the effects including Neat Video are using one pool of memory. By default Premiere Pro reserves sufficient amount of memory for its own needs, which may leave plug-ins and other memory users starving. So in order to achieve faster render you need to make sure there are enough resources for everyone in your editing eco-system.

Adobe recommends 16 GB for editing FulHD video and 32 GB for 4K, although we feel these recommendations are a bit on a lower side. Another thing we would suggest is to check the amount of RAM reserved for non-Adobe applications (Preferences > Memory in Premiere Pro) - if this setting is too low (which it is by default), other memory users (including plug-ins such as Neat Video) may not get enough memory.

Here is an example of the speed we are getting on a computer with 2080Ti and 64 GB DDR4 working with FullHD video

ASRock X570 Taichi, Ryzen 9 3900X, 64 GB DDR4 @2400 MHz  MSI GeForce RTX 2080 Ti VENTUS

Frame Size: 1920x1080 progressive
Bitdepth: 32 bits per channel

40.7 frames/sec (best performance: GPU only) -- this is the speed of Neat Video only

Premiere maybe yes: depends on the format/codec.

Neat Video: no. It mainly uses the cpu and the gpu acceleration when supported.
