Timescale Not Working

[Gitgitgiub]

I've been using blur for a long time now, but I need to speed up my footage a bit. When I try to set the timescale, I get an error. Here's the error message:

Filtergraph 'asetrate=48000*2.0' was defined for audio output stream 0:1 but codec copy was selected.
Filtering and streamcopy cannot be used together.
Error: fwrite() call failed when writing frame: 1, plane: 0, errno: 32
Output 4 frames in 0.70 seconds (5.74 fps)

This is what I entered in the configuration:

- timescale
input timescale: 1
output timescale: 2
adjust timescaled audio pitch: false

Can anyone help me with this? This is my first time using the timescale, and I'm not sure how it works.
