# Membrane Framerate Converter Plugin
[](https://hex.pm/packages/membrane_framerate_converter_plugin)
[](https://hexdocs.pm/membrane_framerate_converter_plugin)
[](https://circleci.com/gh/membraneframework/membrane_framerate_converter_plugin)
Plugin providing element for converting frame rate of raw video stream.
It is part of [Membrane Multimedia Framework](https://membraneframework.org).
## Installation
The package can be installed by adding `membrane_framerate_converter_plugin` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:membrane_framerate_converter_plugin, "~> 0.8.2"}
]
end
```
## Description
Element converts video to target constant frame rate, by dropping and duplicating frames as necessary
(input video may have constant or variable frame rate).
## Usage
Example converting h264 video from 10 to 2 fps.
```elixir
defmodule Pipeline do
use Membrane.Pipeline
alias Membrane.H264.FFmpeg.{Decoder, Encoder}
alias Membrane.H264.Parser
alias Membrane.File.{Sink, Source}
@impl true
def handle_init(_ctx, filename) do
structure =
child(file: %Source{chunk_size: 40_960, location: filename})
|> child(parser: %Parser{generate_best_effort_timestamps: %{framerate: {10, 1}}})
|> child(decoder: Decoder)
|> child(converter: %Membrane.FramerateConverter{framerate: {2, 1}})
|> child(encoder: Encoder)
|> child(sink: %Sink{location: "output.h264"})
{[spec: structure], %{}}
end
end
```
