Dear Bat:

Thank you. You are correct the input file is a variable frame rate. The
command you suggest to convert both video and audio and to force a contact
frame rate worked!!!

I really appreciate your help and the help from this mailing list. I think
this issue is resolved for me now. I will play a bit more now with the
command you suggested below. Thank you once again.
ffmpeg -i telecomcto.flv -c:v libx264 -crf 23 -preset medium -vsync 1 -r 25
-c:a aac -strict -2 -b:a 64k -ar 44100 -ac 1 Xtelecomctotest.mp4

I have also been informed that I have been "top-posting". I looked this up
and I didn't realize I was doing this. However I do realize top-posting
makes things difficult. I apologize for top-posting and I think I have
corrected it in this reply.
