[FFmpeg-user] need help with 'drawtext' usage

[pgoldweic]

I see. Thanks again for your response. Unfortunately I now run into a
different error when I try to encode the video (using h264), as ffmpeg gives
me an 'invalid pixel format string '-1' (error opening filters). 
I am using the following command: 
ffmpeg -i mymovie.mov -vcodec libx264 -acodec copy -vf
"drawtext=fontfile=arial.ttf:text='test'" -f mp4 mymovie.mp4


I did not get the error above when I tried using a different type of movie
instead (an 'mpg' movie). Is there a way to get ffmpeg to work with
Quicktime movies, perhaps passing in further arguments?
Thanks in advance
