It is also possible to apply multiple filters to an input, which are sequenced together in the filtergraph. A chained set of filters is called a filter chain, and a filtergraph may include multiple filter chains. Filters in a filterchain are separated from each other by commas (,
), and filterchains are separated from each other by semicolons (;
). For example, take the inverse telecine command:
ffmpeg -i input_file -c:v libx264 -vf "fieldmatch,yadif,decimate" output_file
Here we have a filtergraph including one filter chain, which is made up of three video filters.
-It is often prudent to enclose your filtergraph in quotation marks; this means that you can use spaces within the filtergraph. Using the inverse telecine example again, the following filter commands are all valid and equivalent: +
