Comment:

 Replying to [ticket:2769 Charlie]:
 > Do you know how to combine two expressions to write text, for instance,
 on every frame between frames 10 and 42 ?

 The following works fine here:
 {{{draw='if(gt(n,10),lt(n,42))'}}}
 See http://ffmpeg.org/ffmpeg-all.html#Expression-Evaluation and please
 understand that this is a bug tracker, post usage questions on the ffmpeg-
 user mailing list.
