Concepts

OBS

Object Storage Service (OBS) is a stable, secure, efficient, and easy-to-use cloud storage service. MPC uses OBS to manage media files. MPC transcodes the media files stored in input buckets and then saves the transcoded files to output buckets. For more information about OBS, see OBS Help Center.

Bucket

Buckets are containers for storing objects. OBS provides flat storage in the form of buckets and objects. Unlike the conventional multi-layer directory structure of file systems, all objects in a bucket are stored at the same logical layer.

SMN

The Simple Message Notification (SMN) service notifies you of your transcoding task status. For more information about SMN, see SMN Help Center.

Transcoding Template

A transcoding template is a set of transcoding parameters, such as audio, video, and container parameters. You can select a system template to save a lot of configuration operations. If you have special requirements, you can customize a transcoding template.

Low Bitrate HD

Based on the human visual system model and Huawei's transcoding technology, MPC analyzes each scenario, action, content, and texture in a video to deliver lower bitrate while keeping the bandwidth costs down but without compromising the video quality.

Fast Transcoding

This allows MPC to transcode video segments in parallel, which can be six times faster than standard transcoding. It is perfect for transcoding videos longer than 30 minutes.

One-in Multiple-out

It is a transcoding method. That is, a video file is transcoded into video files of multiple resolutions and bitrates to meet the playback requirements of different devices and different network speeds.

Image Enhancement

The combination of the traditional super-resolution algorithm and AI-powered image enhancement algorithm converts 2K videos to 4K videos, repairs damaged images, and improves the image quality of existing videos.
