Topic: Transcoding output is the same frame rate as original

I've installed SVP recently and tried to turn 30fps videos to 60fps but although everything seems to work successfully the output is still 30fps despite the transcoding process returning no errors and saying it's converted the video to 60fps.
The video output looks and plays absolutely fine, but the frame rate is completely unchanged. Similarly it seems to attach to VLC fine but I get no SVP overlay and the video looks the same as well.

This is an Ubuntu install.

Re: Transcoding output is the same frame rate as original

I think this is the cause:

20:49:40.767: [vapoursynth] libavfilter filter 'vapoursynth' not found!

You need use mpv build with vapoursynth support.

Re: Transcoding output is the same frame rate as original

I've followed the instructions at https://www.svp-team.com/wiki/SVP:Linux and vapoursynth and mpv with vapoursynth both built and installed successfully. I tried doing this again and I have the same problem.
The one bit that did confuse me is "Just add --input-ipc-server=/tmp/mpvsocket to mpv args (or config file) and SVP should find it." I found a mpv.conf file in mpv-build/mpv/etc and added the two suggested lines to the end of that file, is that correct?
This is what the file looks like for me:

#
# Example mpv configuration file
#
# Warning:
#
# The commented example options usually do _not_ set the default values. Call
# mpv with --list-options to see the default values for most options. There is
# no builtin or example mpv.conf with all the defaults.
#
#
# Configuration files are read system-wide from /usr/local/etc/mpv.conf
# and per-user from ~/.config/mpv/mpv.conf, where per-user settings override
# system-wide settings, all of which are overridden by the command line.
#
# Configuration file settings and the command line options use the same
# underlying mechanisms. Most options can be put into the configuration file
# by dropping the preceding '--'. See the man page for a complete list of
# options.
#
# Lines starting with '#' are comments and are ignored.
#
# See the CONFIGURATION FILES section in the man page
# for a detailed description of the syntax.
#
# Profiles should be placed at the bottom of the configuration file to ensure
# that settings wanted as defaults are not restricted to specific profiles.
