Overview

When using the data processing workflow feature, you usually need to set a series of parameters, which can be combined through a template. This simplifies your operations and allows you to reuse the configured parameters with no need to enter them repeatedly.

For media processing features such as audio/video transcoding, audio/video splicing, video frame capturing, and video to animated image conversion, you need to specify a template when creating a job or workflow. The template page provides system templates, and you can also customize templates based on your business needs.

System Templates

The system combines common parameters in advance into system templates, so that you can use them directly. When creating a job or workflow, you can select such a template by the template name.

1. Log in to the COS console.
2. Click Bucket List on the left sidebar.
3. Click the name of the bucket that you want to operate.
4. On the left sidebar, select Data Processing Workflow > Template Configuration to view templates of different processing types.
   
   Click View in the Operation column to view template details.

   Note：

   • Currently, the system provides 15 audio/video transcoding, 3 video frame capturing, and 18 video to animated image conversion templates.
   • You can view the information of system templates but cannot edit or delete them.

Custom Template

If system templates cannot meet your needs, use custom templates. Currently, you can create custom templates for audio/video transcoding, top speed codec transcoding, highlights generation, video frame capturing, video to animated image conversion, video watermark, audio/video splicing, voice/sound separation, video enhancement, super-resolution, image processing, and broadcast media format transcoding.

Audio/Video transcoding

The audio/video transcoding feature converts an audio/video file bitstream. It changes parameters of the source bitstream, such as codec, resolution, and bitrate, to adapt to different devices and network conditions. You can customize the template parameters in a custom audio/video transcoding template.

Directions

1. Log in to the COS console.
2. Click Bucket List on the left sidebar.
3. Click the name of the bucket where you want to store the video.
4. On the left sidebar, select Data Processing Workflow > Template Configuration to enter the template configuration page.
5. Select Media Processing > Audio/Video Transcoding and click Create Transcoding Template.
   
6. In the Create Transcoding Template window, configure the following items:

• Template Name: It can contain up to 64 letters, digits, underscores (_), hyphens (-), and asterisks (*).
• Transcoding Type: You can select video or audio transcoding.
• Container Format: Video transcoding supports the MP4, FLV, HLS, TS, MKV, and WebM formats. Audio transcoding supports the MP3, AAC, AMR, FLAC, and WebM formats.
• Encoding Format: H264, H265, AV1, VP8, and VP9 are supported.
• Bitrate: Adaptive bitrate is supported, which can automatically analyze the video content to set the optimal bitrate.
• Transcoding Duration: You can select the input file duration or customize the duration.
• Audio/Video Parameters: You can customize audio/video parameters as needed.

7. Click OK.
   After successfully creating the template, you can view, edit, or delete it in the custom template list.

   Note：

   You can use the template when creating an audio/video transcoding job as instructed in Configuring Job or creating a workflow as instructed in Configuring Workflow.

TSC transcoding

The top speed codec transcoding feature improves the subjective image quality of a video at a low bitrate.

    • By ratio: You can set the percentage (100–300) of only the width or height or both of them. If the width or height is not set, it will be scaled proportionally. Suppose the width ratio is a and height ratio is b, then the watermark width will be w = W * a, and the watermark height will be h = H * b (here, W and H are the video width and height respectively).

  • Fixed size: You can specify the watermark width and height between 8 and 4096 px.

  • Offset Method (Underneath video):

    • By ratio: You can set the percentage (-300–0) of the width or height. As shown below, suppose the horizontal offset ratio is a and the vertical ratio is b, then the horizontal offset will be Dx = W * a, and the vertical offset will be Dy = H * b (here, W and H are the video width and height respectively).
    • Fixed position: Select a value between -4096 and 0 px. The horizontal offset is Dx, and the vertical offset is Dy.

• Text watermark parameters

  • Watermark Text: It can contain up to 64 letters, digits, underscores (_), hyphens (-), and asterisks (*).
  • Font Size: Select a value between 5 and 100 px.
  • Font: Select Ariblk, Arial, Ahronbd, Helvetica, or HelveticaNeue.
  • Font Color: It is in the format of 0xRRGGBB.
