# 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.
