<p>I have tried very hard looking for an option to fade in and fade out the text and the box but can't seem to find a solution. Any help is much appreciated </p>

Hmm maybe you can check something like `ffmpeg -i input.avi -vf drawtext="fontfile=/usr/share/fonts/truetype/freefont/FreeSerif.ttf: text='TEXT':fontcolor=white@0.8:, fade=in:0:80" -y output.avi` and also look this question for more info: http://video.stackexchange.com/questions/14924/ffmpeg-drawtext-clipping-to-a-bounding-box If you find a solution please share even by auto-replying :D

That does not work, I get a error saying -
[Parsed_drawtext_0 @ 0x7fc880436b80] Could not load font "/usr/share/fonts/truetype/freefont/FreeSerif.ttf": cannot open resource
[AVFilterGraph @ 0x7fc880422940] Error initializing filter 'drawtext' with args 'fontfile=/usr/share/fonts/truetype/freefont/FreeSerif.ttf: text=TEXT:fontcolor=white@0.8'
Error opening filters!

man I copied you that as example... I assumed you know know a bit of ffmpeg syntax and also you was able to change that font with one other else that you would like to use.. in your case based on your previous example you can use `fontfile=roboto.ttf` ;D

Apologies... I copied the wrong output from the console...I was in a hurry. How stupid of me. I was having errors just using the fade=in:0:80.... and my intention in copying the console output was so you can tell me if I had to recompile ffmpeg with someother configuration. I do know enough to change the font. My apologies
