When converting animated GIFs to [`MP4`](https://www.fastly.com/documentation/reference/io/format) format and when used in conjunction with the [`level`](https://www.fastly.com/documentation/reference/io/level) parameter, the `profile` parameter controls which features the video encoder can use based on a target class of application for [decoding the specific video bitstream](https://en.wikipedia.org/wiki/Advanced_Video_Coding#Profiles).

## Syntax

```text
profile={value}
```

## Allowed values

| Value      | Description                                                                         |
