Overview

You can preset different processing parameters for different application scenarios by configuring audio/video transcoding templates, so that they can be reused later.
If you need to process video files, you can configure video transcoding templates, including general video transcoding templates, Top Speed Codec (TSC) transcoding templates, video adaptive bitrate streaming templates, and remuxing templates.
If you need to process audio-only files, you can configure audio transcoding templates, including general audio transcoding templates, TSC audio transcoding templates, and audio adaptive bitrate streaming templates.
For a brief introduction to each feature, refer to the table below:
Applicable Input Source
Feature
Description
Video
General transcoding
It can reduce the video bitrate and change the encoding standard, resolution, frame rate, and other parameters of the original bitstream, thus adapting to playback on different terminals and in different network environments.
TSC transcoding
TSC transcoding is an "upgrade" of General Transcoding. It can adaptively optimize different types of videos, providing users with a clearer viewing experience at lower bandwidth. While ensuring or even improving image quality, it can save bandwidth costs by 50%+.
Video adaptive bitrate streaming
It can convert the input original video file into multiple bitstreams suitable for playback in different scenarios, so that users can choose a video with an appropriate bitrate for playback based on their network, thereby enhancing user experiences.
Remuxing
It can change the container format of the original video file.
Audio

It is used to specify the number of the first few video segments to take effect when Segment Duration at Startup is enabled. Enter an integer value greater than or equal to 1.
Video Parameters
Encoding standard
H.264, H.264 intra, H.265, AV1, H.266, MV-HEVC, MPEG2, VP8, and VP9.

Resolution & Bitrate

Bitrate Control Mode
The following four bitrate control modes are supported:
1. VBR (default): variable bitrate. The bitrate of the output is adjusted dynamically based on the complexity of video images, resulting in higher image quality. It is suitable for storage scenarios as well as applications requiring high image quality.
2. ABR: average bitrate. The average bitrate of the output video is kept stable to the greatest extent, but short-term bitrate fluctuations are allowed. It is suitable for scenarios where minimizing the overall bitrate is required while a certain image quality is maintained.
3. CBR: constant bitrate. The bitrate of the output is kept constant during the video encoding process without considering changes in image complexity. It is suitable for scenarios with strict network bandwidth requirements.
4. CRF: constant quality factor. Video quality is controlled by setting a quality factor to achieve constant quality encoding of videos, with the bitrate adjusted automatically based on the complexity of the content. It is suitable for scenarios requiring stable image quality.
CRF Value
Video constant bitrate control factor, supporting the following two modes:
Automatic: The CRF value is automatically selected.
Custom: The range of the CRF value is 0 to 51, where 0 means lossless compression and 51 means maximum compression. The typically recommended value range is 18 to 28, where 18 represents a low compression ratio with high quality and 28 represents a high compression ratio with low quality.
Note:
When the bitrate control mode is set to VBR and the CRF value is configured, MPS will process the video in VBR mode according to the CRF value and the average bitrate upper limit, to balance the video quality, bitrate, transcoding efficiency, and file size.
When the bitrate control mode is set to CRF, the average bitrate upper limit setting will be invalid, and encoding will be performed according to the CRF value.
When the bitrate control mode is set to ABR or CBR, the CRF does not need to be set.
Proportional Compression Bitrate
Disabled (default).
Enabled: The bitrate of the output video will be adjusted based on the input compression ratio.
Compression Ratio
It is used when Proportional Compression Bitrate is enabled. The compression ratio is an integer within the range of [0, 100].
Recommended Settings
Select the desired output video quality, such as Standard Definition (SD), and the preset video bitrate, resolution, and audio bitrate will be automatically populated for you.
Note: different encoding standards have varying recommended parameters. For more details, refer to the Appendix.
Average Bitrate
The following two modes are supported:
No video bitrate limit is set.
Custom: It is customized within the range of [128, 35000] (in Kbps).
Resolution
The following three modes are supported:
Keep the original: The resolution is consistent with that of the source video.
Scale: The image is scaled proportionally according to the long or short side (width or height), with a size range of [128, 4096] (in px).
Custom: Both the long and short sides (width and height) can be scaled in custom proportion, with a size range of [128, 4096] (in px).
Display Aspect Ratio (SAR)
It is used when the resolution is set to Custom and the aspect ratio of the video differs from that of the source video. The sample aspect ratio (SAR) refers to the pixel aspect ratio of the video and is used to specify the shape of pixels. The following three modes are supported:
Keep the origin (default)
1 : 1
2 : 1
Padding Rules
It is used when the resolution is set to Custom and the aspect ratio of the video differs from that of the source video. The following five modes are supported:
Scale to fill: This will scale the video image to fill the entire display area, which may cause distortion.
Black bars: (default) Black bars are added around the video to maintain the original aspect ratio, which may waste some display space.
White bars: It is similar to the mode of black bars, but white bars are added on the top and bottom/left and right sides of the video.
Gaussian Blur: Applies a Gaussian Blur effect to the stretched or filled areas to reduce visual discomfort.
Intelligent cropping: The video image to be retained is intelligently selected at the time of video cropping.

Frame Rate

The following two video frame rate setting modes are supported:
Keep the original: The frame rate is consistent with that of the source video.
Custom: The frame rate is customized within the range of [1, 120] (in FPS). If the set value exceeds the source frame rate, duplicate frames will be inserted to make up for it.

GOP

Same Origin of GOP Structure
Disabled (default).
Enabled: The GOP is consistent with that of the source file. Once it is enabled, no other GOP parameters need to be set.
GOP Length
The following two modes are supported:
Automatic
Custom: Enter an integer number of frames or duration (in seconds).
Adaptive I-Frame Decision
Disabled (default).
Enabled: MPS will automatically identify transition points between different scenarios in the video and adaptively insert keyframes (I-frames) at these points, thereby improving the video's random accessibility and encoding efficiency.
Max. Number of Consecutive B Frames
Supported options: Automatic, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, and 16.
When the encoding standard is set to H.264 or H.265, it is recommended to select [Automatic] so that MPS can select the optimal number of B frames.
GOP Duration at Startup
Disabled (default).
Enabled: It is used to set the GOP duration of the video at startup (in seconds).

Intelligent
Scenario Configuration
Disabled (default)
Enabled: Video scenarios and transcoding strategies applicable for the template parameter can be selected. MPS will intelligently adjust underlying processing parameters based on the selected scenarios and strategies to achieve better transcoding effects for different scenario characteristics.
Applicable video scenarios
MPS provides several preset video scenarios, with different processing modes configured to adapt to different scenario characteristics:
General Transcoding Scenarios: General transcoding compression scenarios.
PGC High-Definition Movie and TV Drama: The focus is on the viewing experience of movies and TV dramas at the time of compression. ROI encoding is applied based on the characteristics of movies and TV dramas, while high-quality video and audio contents are retained.
High-Definition Material: This scenario involves material resource categories with extremely high requirements for picture quality and includes many transparent picture elements. The compression achieves almost visually lossless quality.
User-Generated Content (UGC): It is suitable for a wide range of UGC/short video scenarios. It optimizes the encoding bitrate and image quality based on the characteristics of short videos and improves business QoS/QoE metrics.
Showroom/e-commerce category: Emphasizes detail clarity and ROI area enhancement during compression, with particular attention to maintaining image quality in facial areas.
Education Category: The emphasis is on the clarity and readability of text and images at the time of compression to help students better comprehend the content, ensuring the clear conveyance of instructional material.
Transcoding strategy
TSC transcoding supports the Standard Compression and Extreme Compression strategies. Different strategies have different underlying transcoding models, which will affect the bitrate, image quality, and other results.
Standard Compression: Standard TSC transcoding, which provides three options:
Low Compression - Image quality preferred
Medium Compression - Comprehensive optimization
High Compression - Bitrate preferred
From top to bottom, the higher the compression level, the smaller the output video file size, and the greater the image quality loss. Using any option of this strategy only incurs TSC transcoding fees.
Extreme Compression: An "upgraded version" of standard compression, with the highest compression level, which maximizes the compression bitrate while ensuring a certain level of image quality, significantly saving bandwidth and storage costs. Using this strategy incurs both TSC transcoding and audio/video enhancement - artifacts removal fees. For details, see Billing Description.
Note:
If the output video is intended for viewing on a TV, it is not recommended to use the extreme compression strategy.

Appendix: Recommended Settings

To accommodate varying requirements for video clarity, it is recommended that you configure the video bitrate, resolution, and audio bitrate according to the following suggested parameters. Please note:
The recommended settings vary across different encoding standards. For instance, the suggested video bitrate under the H.265 encoding standard is generally 60% of that recommended for the H.264 encoding standard.
Compared to standard video transcoding, ultra-high-definition rapid transcoding recommends a lower video bitrate configuration.
