+# ProRes codec registration
+
+## Description
+
+The Apple ProRes video codec, as specified in [SMPTE RDD 36](https://pub.smpte.org/doc/rdd36/).
+
+## Codec ID
+
+```ts
+'prores'
+```
+
+## `EncodedPacket` data
+
+The packet's data must be a `frame()` as defined in [SMPTE RDD 36](https://pub.smpte.org/doc/rdd36/).
+
+## `EncodedPacket` type
+
+Since ProRes is intra-frame-only, every packet is a key frame and its type is therefore always `'key'`.
+
+## `VideoDecoderConfig` codec string
+
+The codec string must be one of the six four-character codes identifying the ProRes profile:
+
+- `'ap4x'` - ProRes 4444 XQ
+- `'ap4h'` - ProRes 4444
+- `'apch'` - ProRes 422 High Quality
+- `'apcn'` - ProRes 422 Standard Definition
+- `'apcs'` - ProRes 422 LT
+- `'apco'` - ProRes 422 Proxy
+
+## `VideoDecoderConfig` description
+
+`description` is not used for this codec.
