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 可以設置rgba四個分量的變換關系，共接受16個參數。
rr rg rb ra
gr gg gb ga
br bg bb ba
ar ag ab aa
參數本質就是加權求值時候的權重，每個參數接受0-1得值，濾鏡本質是將每個顏色值加權求值.公式：
red=red*rr+blue*rb+green*rg+alpha*ra 。green/blue和alpha同理。參數默認值對應得是1，其他為0.如：rr，rg，rb，ra。其中rr默認為1，其他為0。
