Body: <p>What I am trying to achieve is speed up a small portion of a video, lasting only about a second. I tried using Windows Movie Maker. What I did was import the video three times, then trim the three versions so that the first version ended at 16.06 seconds, the second started at 16.06 and ended at 17.54, and the third started at 17.54. Then I sped up the second by .25x.</p>
  
  <p>The result is almost acceptable, but there's a tiny flicker when the second version starts and stops.</p>
  
  <p>Does anyone know how I can get rid of the flicker, or if there's another editing program that is better suited to this task? I think it would be better if the sped up portion was sped up gradually.</p>

Comments.Text: @JimMack If I understand you right, that's exactly what I did. I sped up one copy, sandwiched that copy between two normal-speed copies, and then trimmed all three copies so that they matched up. Is that what you had in mind?

  What I am trying to achieve is speed up a small portion of a video, lasting only about a second. I tried using Windows Movie Maker. What I did was import the video three times, then trim the three versions so that the first version ended at 16.06 seconds, the second started at 16.06 and ended at 17.54, and the third started at 17.54. Then I sped up the second by .25x.
  
  The result is almost acceptable, but there's a tiny flicker when the second version starts and stops.
  
  Does anyone know how I can get rid of the flicker, or if there's another editing program that is better suited to this task? I think it would be better if the sped up portion was sped up gradually.
