Request headers

Header name	Description
x-ncp-region_code	NAVER Cloud Platform's region code `x-ncp_region_code:{Region Code}`
x-ncp-apigw-timestamp	This is the number of milliseconds that have elapsed since January 1, 1970 00:00:00 UTC. If the time difference compared to the API Gateway server is more than 5 minutes, then the request is considered invalid. `x-ncp-apigw-timestamp:{Timestamp}`
x-ncp-iam-access-key	Access key ID value issued by the NAVER Cloud Platform portal `x-ncp-iam-access-key:{Sub Account Access Key}`
x-ncp-apigw-signature-v2	Signature encrypted with the Access Key ID value and Secret Key `x-ncp-apigw-signature-v2:{API Gateway Signature}`
Content-Type	Specify the request body content type as application/json `Content-Type: application/json`

Request body

API field names in the request body are case sensitive.

Field name	Requirement status	Type	Restrictions	Default value	Description
name	Yes	String	3 to 20 characters consisting of English letters, numbers, colons (:), hyphens (-), and underscores (_) are allowed.		Name of user-defined encoding option to be created
format	Yes	String	MP4		Converted media file's container format
encodingOptionType	No	String	NORMAL, AUDIO	NORMAL	- Type of user-defined encoding option Select either the normal preset including video and audio, or audio preset including only audio streams.
audio	Yes	Object			Object for setting transcoding audio option
audio.codec	Yes	String	AAC		Audio codec settings
audio.channel	Yes	String	AUTO, 1, 2		- Output audio's channel settings Use the original audio channel when setting up AUTO `참고: 인풋 미디어 파일의 오디오 채널과 다른 설정으로 인코딩 시 볼륨의 변화가 발생 할 수 있음`
audio.bitrate	Yes	Integer	An integer between 16 and 320, unit: Kbps		Bit transfer rate settings of the video stream subject for transcoding
audio.samplingRate	Yes	Integer	AUTO, -2, 22050 , 32000, 44100, 48000 Unit: Hz		Output audio's sampling rate settings. The source's audio sampling rate is used when set to AUTO.
video	Yes	Object			- Object for setting transcoding video option The video object is omitted when encodingOptionType is AUDIO.
video.codec	Yes	String	AVC		Video codec settings Supports AVC (H.264)
video.codecOptions	Yes	Object			Object for setting video codec detailed options
video.codecOptions.profile	Yes	String	BASELINE, MAIN, HIGH		Video codec profile is a pre-defined standard specification so specific technologies of the H.264 codec can be used according to the video's purpose of use.
video.codecOptions.level	Yes	String	1, 1b, 1.1, 1.2, 1.3, 2.1, 2.2, 3.1, 3.2, 4.1, 4.2, 5.1, 5.2		Video codec level is a standard specification set to indicate how many resources are required by the player (decoder) of the device that plays the video.
video.bitrate	Yes	Integer	Bitrate> 0, unit: Kbps		Video stream's bit transfer rate settings. It's a very important element that determines the video's image quality, and it also decides how much data is in a 1 second video.
video.width	Yes	Integer	AUTO (-2), an integer between 96 and 4096, unit: pixel		The horizontal length of the output video. If only the output video's width is set to AUTO, then the height will be fixed and the width will change according to the video's ratio.
video.height	Yes	Integer	AUTO (-2), an integer between 96 and 4096, unit: pixel		The vertical length of the output video. If only the output video's height is set to AUTO, then the width will be fixed and the height will change according to the video's ratio.
video.framerate	Yes	Double	AUTO(-2), 10, 15, 23.97, 24, 29.97, 30, 50, 60		Sets the number of frames per second and how many frames per second to show in a video stream.
video.maxFramerate	No	Integer	Integer value between 10 and 60		Only used when video.framerate is AUTO and sets the maximum framerate.
video.keyframeInterval	Yes	Integer	An integer between 1 and 100		Key frame interval settings, interval of key frames created in video (unit: seconds)
video.rateControl	Yes	String	AUTO,ABR, CRF, CBR Only ABR is allowed when the video.pass is 2-pass.	ABR	- Bitrate distribution method when converting videos CBR: fixed bitrate, converts with equal bitrates in all frames. The bitrate is fixed, which makes predicting the result's size easy, but the quality is low compared to ABR or CRF. CRF: has good compression efficiency, but the bitrate and file size can't be specified before encoding. ABR: converts variably according to bitrate needed while maintaining an average bitrate with available bitrates.
video.pass	Yes	String	1-Pass, 2-Pass		- Encoding method to be used when converting video 2-pass uses given bitrates more efficiently than 1-pass, but the encoding time is longer.
