The transcoded audio and video specifications can be customized based on yourneeds. For details, see Table 2-1, Table 2-2, Table 2-3, and Table 2-4.

Table 2-1 Video encoding parameters


Video Codec The value can be H.264 or H.265. The default valueis H.264.

Resolution (video widthand video height)

● H.264– Video width: [32, 4,096] or 0. The unit is px.– Video height: [32, 2,880] or 0. The unit is px.

● H.265– Video width: [160, 4,096] or 0. The unit is px.– Video height: [96, 2,880] or 0. The unit is px.

If the video width and height are both set to 0, thetranscoded video is produced based on the originalresolution. If the video bandwidth or height is setto 0, the corresponding value is adjusted based onthe original size.

Bitrate Video bitrate. The value can be 0 or ranges from 40to 30,000. The unit is kbit/s.If this parameter is set to 0, an output file isgenerated at the adaptive bitrate.

Transcoding Templates

MPC provides plenty of built-in transcoding templates to meet your diverserequirements. You can also create a transcoding template to target your specificscenario.

● Preset templates: You can directly use these templates without any otherconfiguration. There are audio templates, audiovisual templates, and lowbitrate HD templates, covering all output formats, encoding formats, andcommon resolutions and bitrates. Based on the number of output files, presettemplates are classified into the following types:– One-in and one-out transcoding template: Only one output file is

generated.– One-in multiple-out transcoding template: A maximum of nine output

files can be generated.● Custom templates: Set the video and audio parameters based on your needs.

A custom template can be a one-in and one-out transcoding template or one-in and multiple-out transcoding template. A maximum of six outputspecifications can be configured for a one-in multiple-out template.

Low Bitrate HD

MPC uses perceptual coding to analyze each scenario, action, content, and texturein a video, achieving lower bitrate and bandwidth usage at a given video quality.

Video Watermark● You can add both image and text watermarks to videos.● The input format can be PNG, JPG, or JPEG.● A maximum of two static images can be overlaid on an output video per

frame.● A maximum of 10 static images can be overlaid on each output video.● The resolution of a watermark cannot be lower than 8x8 and greater than

4,096x4,096. The size of the watermark cannot exceed 10 MB.

Frame Capture

Capture a frame from a video and save it as a JPG file. You can take a snapshotduring transcoding or at any other time. The following two capture methods aresupported:

● By interval: Take snapshots at regular intervals. The default interval is 12s.● At fixed time: Take snapshots at specified time points.

5 Concepts

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

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

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

Transcoding TemplateA 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 ofconfiguration operations. If you have special requirements, you can customize atranscoding template.

Low Bitrate HDBased on the human visual system model and Huawei's transcoding technology,MPC analyzes each scenario, action, content, and texture in a video to deliverlower bitrate while keeping the bandwidth costs down but without compromisingthe video quality.

Fast TranscodingThis allows MPC to transcode video segments in parallel, which can be six timesfaster than standard transcoding. It is perfect for transcoding videos longer than30 minutes.

6 Region and AZ

ConceptsA region and availability zone (AZ) identify the location of a data center. You cancreate resources in a specific region and AZ.

● Regions are divided from the dimensions of geographical location andnetwork latency. Public services, such as Elastic Cloud Server (ECS), ElasticVolume Service (EVS), Object Storage Service (OBS), Virtual Private Cloud(VPC), Elastic IP (EIP), and Image Management Service (IMS), are sharedwithin the same region. Regions are classified as universal regions anddedicated regions. A universal region provides universal cloud services forcommon tenants. A dedicated region provides services of the same type onlyor for specific tenants.

● An AZ contains one or multiple physical data centers. Each AZ hasindependent cooling, fire extinguishing, moisture-proof, and electricityfacilities. Within an AZ, computing, network, storage, and other resources arelogically divided into multiple clusters. AZs within a region are interconnectedusing high-speed optical fibers to allow you to build cross-AZ high-availabilitysystems.

Figure 6-1 shows the relationship between regions and AZs.

Figure 6-1 Regions and AZs

Media Processing CenterService Overview 6 Region and AZ


HUAWEI CLOUD provides services in many regions around the world. You canselect a region and AZ as needed. For more information, see HUAWEI CLOUDGlobal Regions.

How to Select a Region?When selecting a region, consider the following factors:

● LocationYou are advised to select a region close to you or your target users. Thisreduces the network latency and improves the access speed. Regions withinthe Chinese mainland provide the same infrastructure, BGP network quality,as well as resource operations and configurations. Therefore, if your targetusers are in the Chinese mainland, you do not need to consider the networklatency differences when selecting a region.– If you or your target users are in the Asia Pacific area outside the Chinese

mainland, select the AP-Hong Kong, AP-Bangkok, or AP-Singaporeregion.

– If you or your target users are in Africa, select the AF-Johannesburgregion.

– If you or your target users are in Europe, select the EU-Paris region.● Resource price

Resource prices may vary in different regions. For details, see Product PricingDetails.

How to Select an AZ?When determining whether to deploy resources in the same AZ, consider yourapplication's requirements on disaster recovery (DR) and network latency.

● For high DR capability, deploy resources in different AZs in the same region.● For low network latency, deploy resources in the same AZ.

Regions and EndpointsBefore using an API to call resources, specify its region and endpoint. For moredetails, see Regions and Endpoints.
