I'm using the basic drawtext command like this
ffmpeg -i output.mp4 -vf \
'drawtext=textfile='textfile.txt':x=0:y=0 \
:fontsize=30:fontcolor=white:borderw=3 \
:bordercolor=black:box=0' output.mp4"
which puts stationary text at location (x, y) = (0,0)
What I want to do is move this text by 10 points in y plane at certain time codes.
at 00:00:10, y would be 0
at 00:00:11, y would be 10
at 00:00:43, y would be 20
...
...
at 00:10:44, y would be 30
so the 'y' co-ordinate has a fix increment of 10 at 'keytimes'
Is there a way to do that?
