Body: <p>Based on some of my videos I would like to make time-lapse videos with motion blur. My inspiration is this YouTube video:</p>
  
  <p><a href="https://youtu.be/60PwmV-_1vg?t=402" rel="nofollow noreferrer">Time-lapse with motion blur from video with Avidemux, AviSynth and VirtualDub</a>   (starting at 6:42)</p>
  
  <p>In the video the man uses VirtualDub with </p>
  
  <pre><code>AviSource("path") 
  Merge(selectEven(), SelectOdd()) 
  Merge(selectEven(), SelectOdd()) 
  Merge(selectEven(), SelectOdd()) 
  Merge(selectEven(), SelectOdd()) 
  AssumeFPS(30)
  </code></pre>
  
  <p>My source video has 60fps. Based on the tips given here I tried:</p>
  
  <pre><code>ffmpeg -i IN.MOV \
    -vf "tblend=average,framestep=2,tblend=average,framestep=2,setpts=0.25*PTS" \
    -r 60 -an OUT.MOV
  </code></pre>
  
  <p>Unfortunately my results are not similar, not so good as in the video. Difficult to say where the different is: the time-lapse effect is missing a bit, the motion blur is “different”? I am sorry, I cannot explain.</p>
  
  <p>Maybe some of you have a tip how to switch die VirtualDub approach to FFmpeg regardless of my poor explanation?</p>
  
  <p>Thanks in advance!</p>

Comments.Text: I think there is something missing. The guy here in this video is joining files in this program amd programing in this... he cant remember how he got the "Right" codec... Smells fishy. You need to get some good tools ro get good looking finished product. At the very least find an old version of adobe pr even the Free version of AVID...

  I have no idea how your video looks, and why it looks different. And I have no idea on what settings you can put to your script. Sorry about that.
  
  What I want to mention, (which is a bit long for just a comment) is that the amount of blur you see on the video greatly depends on how many frames you are compressing on one "time-lapsed" frame.
  
  Take a look at this closeup of the video you posted. You can clearly see that the motion blur is added on the top of a lot of frames merged.

  So, there is a chance that the other video has a different number of frames, or was shot at a different framerate, therefore when compressed, they have more frames to work with.
