So I have an audio file 1.4 Mb (.ogg) and a video file 57 Mb (.ogv) and
they need putting together (with 1.4 seconds trimmed from the audio to
sync up).

Does anyone have software to do this?

ffmpeg -i audio.ogg -i video.ogv -acodec copy -vcodec copy -f mkv output.mkv

or whatever container you prefer

to sync them see:
