title: Create a series of text clip and concatenate them into a video using moviepy
body: <ol>
  <li>In MoviePy there is an api to create a clip from text as well as to concatenate list of clips.</li>
  <li>I am trying to create a list of clips in a loop and then trying to concatenate them. </li>
  <li>Problem is every time it creates a video file of 25 seconds only with the last text in a loop.</li>
  </ol>
  
  <p>Here is the code </p>
  
  <pre><code>for text in a list:
      try:
          txt_clip = TextClip(text,fontsize=70,color='white')
          txt_clip = txt_clip.set_duration(2)
          clip_list.append(txt_clip)
      except UnicodeEncodeError:
          txt_clip = TextClip("Issue with text",fontsize=70,color='white')
          txt_clip = txt_clip.set_duration(2) 
          clip_list.append(txt_clip)
  final_clip = concatenate_videoclips(clip_list)
  final_clip.write_videofile("my_concatenation.mp4",fps=24, codec='mpeg4')
  </code></pre>
