       This can be done in two steps:

             1.  Convert the text files to graphics, e.g., plot001.png, 
plot002.png, ..., plot300.png.  For this I routinely use R (r-project.org).

             2.  "ffmpeg -y -r 300 -i plot%d.png -b 300k -pix_fmt 
yuv420p tst.mp4".  This was discussed in a recent thread I initiated on 
"Windows Media Player cannot play the file" 
(http://ffmpeg.org/pipermail/ffmpeg-user/2014-March/subject.html). The 
first email on this thread included 3 png files that were successfully 
combined using a version of this command in the seventh email in this 

       Hope this helps.
