<dd><p>In VapourSynth the resizers have several functions. In addition to scaling,
they also do colorspace conversions and conversions to and from the compat
formats. Resize converts a clip of known or unknown format to another clip
of known or unknown format, changing only the parameters specified by the
user. The resize filters can handle varying size and format input clips
and turn them into constant format clips.</p>
<p>If you do not know which resizer to choose, then try Bicubic. It usually
makes a good neutral default.</p>
<p><em>Bob</em> can be used as a rudimentary deinterlacer.</p>
<p>Arguments denoted as type <em>enum</em> may be specified by numerical index (see
ITU-T H.265 Annex E.3) or by name. Enums specified by name have their
argument name suffixed with “_s”. For example, a destination matrix of
BT 709 can be specified either with <code class="docutils literal notranslate"><span class="pre">matrix=1</span></code> or with <code class="docutils literal notranslate"><span class="pre">matrix_s=&quot;709&quot;</span></code>.</p>
<p>Note that <em>matrix</em> is not an optional argument when converting to YUV.
Also note that if no matrix is specified in an input YUV frame’s properties
then <em>matrix_in</em> also needs to be set.</p>
<p>The function will return an error if the subsampling restrictions aren’t
followed.</p>
<p>If you get an error like:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">Resize</span> <span class="n">error</span> <span class="mi">3074</span><span class="p">:</span> <span class="n">no</span> <span class="n">path</span> <span class="n">between</span> <span class="n">colorspaces</span> <span class="p">(</span><span class="mi">2</span><span class="o">/</span><span class="mi">2</span><span class="o">/</span><span class="mi">2</span> <span class="o">=&gt;</span> <span class="mi">1</span><span class="o">/</span><span class="mi">1</span><span class="o">/</span><span class="mi">1</span><span class="p">)</span><span class="o">.</span>
<span class="n">May</span> <span class="n">need</span> <span class="n">to</span> <span class="n">specify</span> <span class="n">additional</span> <span class="n">colorspace</span> <span class="n">parameters</span><span class="o">.</span>
</pre></div>
</div>
<p>It usually means the matrix/transfer/primaries are unknown and you have to
specify the input colorspace parameters yourself. Note: 2 means “unspecified”
according to the ITU-T recommendation.</p>
<p>Resizing is performed per-field for interlaced images, as indicated by the
<em>_FieldBased</em> frame property. Source filters may sometimes mark progressive
video as interlaced, which can result in sub-optimal resampling quality
unless <em>_FieldBased</em> is cleared.</p>

the input format is 4:4:4 or RGB and the output is subsampled, the default location
