Preset narrowband HD templates
Note: Preset narrowband HD templates are a type of transcoding templates unique to Alibaba Cloud Media Processing. While maintaining the same video definition as common transcoding templates, they provide a lower bit rate to reduce your costs.

Preset static templates
Compared with a preset smart template, a preset static template does not have to be analyzed before being called. Preset static templates include video transcoding templates, audio MP3 transcoding templates, and conversion and encapsulation templates.
1. Video transcoding templates
A video transcoding template basically controls the resolution when duly controlling the bit rate. Each preset static template outputs a fixed preset resolution width. The resolution height scales down at the original aspect ratio.

2. Conversion and encapsulation templates
A conversion and encapsulation template does not recode the input media file, but only converts the format of the file. Operations that require recoding, such as watermarking, editing, and joining, are not supported.
NOTE: Conversion and encapsulation may fail because the sources and formats of input media files are not supported. In this case, transcoding tasks using the conversion and encapsulation template fail to run.

| Template ID | Template name | Description | Container format |
|---|---|---|---|
| S00000001-000000 | FLV-COPY | Convert to the FLV format. | FLV |
| S00000001-100000 | M3U8-COPY | M3U8 slice | M3U8 |
| S00000001-200000 | MP4-COPY | Convert to the MP4 format. | MP4 |
3. Audio transcoding templates
Currently, audio transcoding templates only support output in MP3 format and are used to control the bit rate.

| Template ID | Template name | Description | Container format | Maximum bit rate (Kbit/s) |
|---|---|---|---|---|
| S00000001-300050 | MP3-320 | MP3-320 | MP3 | 320 |
| S00000001-300040 | MP3-192 | MP3-192 | MP3 | 192 |
| S00000001-300030 | MP3-160 | MP3-160 | MP3 | 160 |

| S00000001-300010 | MP3-64 | MP3-64 | MP3 | 64 |
4. Resolution doubling templates
The output width and height double the input width and height. The output resolution is determined by the width. If the doubled width exceeds the upper threshold, the width takes the upper threshold value, and the height scales down at the original aspect ratio.
| Template ID | Template name | Description | Container format | Video bit rate (Kbit/s) | Audio bit rate (Kbit/s) | Resolution-width | Remarks |
|---|---|---|---|---|---|---|---|
| S00000001-400070 | MP4-2KTo4K | MP4-2KTo4K | MP4 | ≤20000 | 128 | ≤3840 | Applicable to Web and mobile devices (iOS and Android) |
| S00000001-400040 | MP4-SDToHD | MP4-SDToHD | MP4 | ≤6000 | 128 | ≤1280 | Applicable to Web and mobile devices (iOS and Android) |
Preset smart templates
Note: Before you use a preset smart template when submitting a transcoding task, the preset smart template must be analyzed by Media Processing. An OSS file must proactively call the “SubmitAnalysisJob” API and poll the “QueryAnalysisJobList” API to obtain a list of preset smart templates available for the OSS file.
Opened preset smart templates for bit rate control are as follows (the output resolution fluctuates within a certain range because the resolution is optimized based on the input video):
| Template ID | Template name | Description | Container format | Bit rate range | Resolution |
|---|---|---|---|---|---|
| S00000000-000050 | FLV-FHD | FLV-FHD | FLV | 2 Mbit/s to 4 Mbit/s | [720p，1080p] |
| S00000000-000040 | FLV-HD | FLV-HD | FLV | 1 Mbit/s to 2 Mbit/s | ≥576p |
