title: ffmpeg mjpeg -> h.265 smeared color on output video file
body: <p>I am converting some old mjpeg videos (stored in .avi container) to h.265 (.mp4 container) but am noticing the colors are smearing. Using the terminal command:</p>
  <p><code>ffmpeg -y -i &quot;input-file.avi&quot; -c:v libx265  -vtag hvc1 &quot;output-file.mp4&quot;</code></p>
  <p>I get the following image (notice how the red and blue are stretched donward). There is a lot of motion in the scene, but the motion is mostly horizontal:</p>
  <p><a href="https://i.stack.imgur.com/3s1pH.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/3s1pH.png" alt="enter image description here" /></a></p>
  <p>Any idea what might cause this? The detail and resolution seem fine, just the colors are being interpreted weirdly.</p>
  <p>Full output:</p>
