Hi Michael,
you can use this command.
ffmpeg -i temp.mp4
-filter_complex "[0:v]drawtext=fontfile=arial.ttf: text='TEST':
fontcolor=#[email protected]: fontsize=200"
-codec:v mpeg4 out.mp4
The transparency 40% (fontcolor=#[email protected])

Hi Chandu,
that's not what I want. I want a dynamic expression for the
transparency. The constant will later be replaced by a more complicated
expression (for example a function of time, for slowly fading the text
in and out).
Michael
