I should have thought a little longer. :'-(
Found something that works:
ffmpeg -ss 308 -t 4 -i 00011-00016.MTS -ss 329 -to 374 -i 00011-00016.MTS
-pix_fmt yuv420p -vcodec libx264 -crf 26 -acodec libmp3lame -qscale:a 9 -preset
veryfast -filter_complex '
[0:v][1:v] xfade=transition=hlslice:
duration=4:
offset=0
[v01];
[0:a][1:a] acrossfade=d=4
[a01];
[v01] drawtext=
box = 1:
boxborderw = 6:
boxcolor = black@0.2:
fontcolor = white@0.4:
fontfile = FreeSerifBold.ttf:
fontsize = 32:
text = © 2022 Cecil Westerhof - ce...@decebal.nl:
x = ((main_w - text_w) / 2):
y = main_h - (text_h * 2)
[v02]
' -map '[v02]' -map '[a01]' xfadeMusicalTestTemp/accordeonmuziek.ts
It looks and sounds OK to me. But I do get:

Is this something to worry about?
