• Enhancement: MPS can enhance media files uploaded by users to improve their quality and effectiveness.

Encoding

Encoding includes three different transcoding methods for different scenarios,VOD Transcoding, LIVE Transcoding, WebRTC Transcoding.

In the center of the page is a small screen where you can preview your video. Below the small video, there are video quality metrics and video bitrate provided for users to monitor and evaluate in real-time.

VOD Transcoding

VOD (Video on Demand) transcoding refers to the process of transcoding existing media files. For example, a recorded video file can be transcoded and uploaded to a cloud storage service for users to watch.

• Step 1:

Click the "Select video to encode" button on the right side of the page to upload a new media file. You can choose to upload your own media file or use the example video we provide.

• Step 2:

After the upload is complete, on the right side of the page, select the video format, resolution, audio encoding, and other parameters as needed. MPS will automatically transcode the video according to the user's selection.

1) Select video format container:
MP4 is a popular video container format that can store multiple types of media data such as video, audio, subtitles, and supports various encoding formats such as H.264, AAC, etc.
FLV is a video container format developed by Adobe that can store multiple types of media data such as video, audio, subtitles, and is commonly used for online video and streaming.
HLS is a streaming media transmission protocol developed by Apple that can divide video streams into multiple small segments and transmit them via HTTP protocol.

2) Select encoding methods:
H.264 is widely used in fields such as HD video and online video.
H.265 provides higher video quality and smaller file sizes, suitable for HD video, 4K/8K video, and other fields.
H.266 reduces bitrate by another half compared to H.265, suitable for HD video, 4K/8K video, and other fields.
AV1 provides better video quality and smaller file sizes, suitable for online video, HD video, and other fields.

3) Select Resolution:
Resolution refers to the number and size of pixels in an image or video, usually represented by the number of pixels. For example, the resolution of 8K is 7680x4320. The higher the resolution, the higher the detail and clarity of the image or video, but it also takes up more storage space and bandwidth resources.

4) Default Audio encoding:
AAC (Advanced Audio Coding): AAC is a new generation of audio encoding standard that can compress audio data into smaller file sizes and provide higher sound quality.

5) Select Audio sampling rate:
44100Hz: This is the sampling rate for CD audio quality and one of the most commonly used sampling rates that can provide high sound quality and smaller file sizes.
48000Hz: This is the sampling rate commonly used in fields such as movies, television, and broadcasting, which can provide higher sound quality and a wider range of applications.

6) Select Audio Channels:
Mono: Only one channel, suitable for fields such as voice communication and broadcasting.
Stereo: Two channels, left and right, can provide more realistic sound effects, suitable for fields such as music and movies.
