<p><b>Note</b>: If you wish to embed colourspace metadata <i>without</i> changing to another colourspace, omit <code>-vf colormatrix=src:dst</code>. However, since it is <code>libx264</code>/<code>libx265</code> that writes the metadata, it’s not possible to add these tags without reencoding the video stream.</p>
<p>For all possible values for <code>-color_primaries</code>, <code>-color_trc</code>, and <code>-colorspace</code>, see the ffmpeg documentation on <a href="./index.html#Codec-Options" target="_blank">codec options</a>.</p>
