<p>This is a lost cause since the interlaced video got already compressed by youtube destroying the pattern, you will not get a clean progressive video from this.</p>

I would think so, but the OP says: *I've used Yadif filter on other Youtube videos before, and it works every time except this one.*

<p>I want to use a small part of this video:
<div class="youtube-embed"><div>
                <iframe width="640px" height="395px" src="https://www.youtube.com/embed/RuCnZClWwpQ?start=0"></iframe>
            </div></div> .
It has very bad interlacing that I need to get rid of.</p>

<p>I downloaded the mp4 file, which is 1920x1080, 29.971 fps. I don't know much about video processing, and the only thing I can use is avidemux. So I followed this tutorial: <a href="http://www.avidemux.org/admWiki/doku.php?id=tutorial:deinterlacing_video" rel="nofollow">http://www.avidemux.org/admWiki/doku.php?id=tutorial:deinterlacing_video</a> .
I tried the Decomb Telecide filter as the tutorial says, selecting "No strategy" and leaving the other options as default. But it didn't get rid of the interlacing. Then I tried the Yadif filter, and then both filters together, and none of these gave any improvement to the video. The interlacing is still very bad, and I don't know why. I've used Yadif filter on other Youtube videos before, and it works every time except this one. </p>

<p>Which filter and what options should I choose to deinterlace this video properly?</p>

Which filter and what parameters should I use to deinterlace this video?
