-The geometry parameters are:
+### `geometry`
+
+The `geometry` option has the following available modifiers:
 
 1. '!' - Keep the same aspect of the image/video, but with the passed dimesion.
 2. '#' - Pad the image/video.
 3. '<' - Enlarge the image/video.
 4. '>' - Shrink the image/video.
 
+### `convert_options`
+
+The `convert_options` option lets you specify custom command line options to be sent to the `ffmpeg` command. The options are split into `output` and `input`, which define where in the pipeline they will be applied. Read more about which flags go where on the [official documentation](https://ffmpeg.org/ffmpeg.html).
+
+For example, sending in the `-an` flag would look like this:
+
+```ruby
+has_attached_file :video, styles: {
+  mobile: {
+    format: "mp4",
+    convert_options: {
+      output: {
+        an: nil # Remove audio track resulting in a silent movie, passing in nil results in `-an`,
+        name: "value" # Results in `-name value` in the command line
+      }
+    }
+  },
+}
+```

 1. A transcoded `:medium` FLV file with the requested dimensions if they will match the aspect ratio of the original file, otherwise, width will be maintained and height will be recalculated to keep the original aspect ration.

-You may optionally add `<attachment>_meta` to your model and it will get populated with information about the processed video.
+### Meta Data
+
+Then paperclip-av-transcoder can optionally add uploaded file meta data to a database column for `<your_attachment>_meta`.
+
+Example: Given a model called `User` with an attachment field named `:avatar`, create a new migration to add an `avatar_meta` column to the `users` table.
+```
+def change
+  add_column :users, :avatar_meta, :data_type
+end
+```
+You can use a data type of `:json`, `:jsonb`, `:hstore`  or even just `:string`. Check what data types your database supports.
