5 Timeline editing
Some filters support a generic <samp>enable</samp> option. For the filters supporting timeline editing, this option can be set to an expression which is evaluated before sending a frame to the filter. If the evaluation is non-zero, the filter will be enabled, otherwise the frame will be sent unchanged to the next filter in the filtergraph.
The expression accepts the following values:
‘t’timestamp expressed in seconds, NAN if the input timestamp is unknown‘n’sequential number of the input frame, starting from 0‘pos’the position in the file of the input frame, NAN if unknown‘w’‘h’width and height of the input frame if video
Additionally, these filters support an <samp>enable</samp> command that can be used to re-define the expression.
Like any other filtering option, the <samp>enable</samp> option follows the same rules.
For example, to enable a blur filter (smartblur) from 10 seconds to 3 minutes, and a curves filter starting at 3 seconds:
<pre class="example" style="margin: 10px 0px 0px; padding: 0px; font-family: ConfluenceInstalledFont, monospace; color: rgb(51, 51, 51); font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">smartblur = enable='between(t,10,3*60)',
curves = enable='gte(t,3)' : preset=cross_process
</pre>

5, colorchannelmixer 可以设置rgba四个分量的变换关系，共接受16个参数。
rr rg rb ra
gr gg gb ga
br bg bb ba
ar ag ab aa
参数本质就是加权求值时候的权重，每个参数接受0-1得值，滤镜本质是将每个颜色值加权求值.公式：
red=red*rr+blue*rb+green*rg+alpha*ra 。green/blue和alpha同理。参数默认值对应得是1，其他为0.如：rr，rg，rb，ra。其中rr默认为1，其他为0。
