[HELP] Can't frame interpolate 4K footage to 60FPS

[acoolrocket]

Hmm,... works fine here.
Avisynth will probably crash with the default setting since it's only 32bit and runs out of RAM.

Video RAM usage is around 1700MB (not using gpu for decoding) so unless you only have Video 2GB of RAM you should be fine.
x264 eats around 3.1GB (changed to crf and set level to 5.2 rest was default) for RAM and Vapoursynth requires ~4.8 GB of RAM here.
-> How much system RAM do you have?

You can lower the RAM usage of Vapoursynth be enabling 'Filtering->Vapoursynth->Misc->Misc->Limit Cache (MB)' on my system limiting it to 1500MB causes Vapoursynth to only use ~2.4GB. (Limiting the thread count in Vapoursynth an x264 will also lower the RAM usage.)

Thanks just gonna drop the system specs here because it shouldn't have a problem with any of the minimum specifications you listed:

Ryzen 7 1800x @Stock
16GB DDR4 (2x8GB) 3000MHz
XFX RX 480 8GB
