What does video transcoding mean?

Video transcoding means converting one video format into another video format. The methods of video transcoding are as follows: 1. Use video editing software, such as Adobe Premiere, Final Cut Pro, iMovie, etc.; 2. Use online transcoding services, such as CloudConvert; 3. Use video transcoding tools, such as Format Factory; 4. Use the transcoding function that comes with your device, such as smartphones, tablets, etc.

What does video transcoding mean? Video transcoding, simply put, is to convert one video format to another video format. In the field of digital video, video transcoding is a process of converting original video data into different formats or encoding standards in order to adapt to different network bandwidths, different terminal processing capabilities, and different user needs. The transcoding process usually involves the conversion, compression and encoding of video formats.

Why do we need to transcode videos?

1. Adapt to different devices and platforms: different devices (such as mobile phones, tablets, computers, etc.) and platforms (such as iOS , Android, Windows, etc.) may support different video formats and encoding standards. Video transcoding allows videos to play properly on a variety of devices and platforms.

2. Optimize video quality and playback experience: Through transcoding, the resolution, frame rate, bit rate and other parameters of the video can be adjusted to adapt to different network bandwidth and terminal processing capabilities. On the premise of maintaining video quality, reduce the video file size and improve the smoothness of video playback.

3. Save storage space: For some devices or platforms, there may be restrictions on video file size. By transcoding, you can reduce the video file size, thereby saving storage space.

4. Improve video transmission efficiency: Under limited network bandwidth conditions, through transcoding, the video bit rate can be reduced, thereby improving the efficiency of video transmission.

The process of video transcoding

The process of video transcoding usually includes the following steps:

1. Preprocessing: raw video data Perform preprocessing, such as cropping, scaling, filtering, etc., to improve the transcoding effect.

2. Decoding: Decode the original video data into pixel data or intermediate representation in other formats.

3. Conversion: Convert the decoded data to the target format or encoding standard. This step may involve operations such as format conversion, color space conversion, compression and encoding.

4. Encoding: Re-encode the converted data to adapt to the target platform or device.

5. Post-processing: Post-process the encoded video data, such as adding watermarks, adjusting bit rate, etc.

6. Encapsulation: Encapsulate the encoded video data into a video file in the target format.

There are many methods of video transcoding

The common ones are as follows:

1. Use video editing software: many video editing software All provide video transcoding functions, such as Adobe Premiere and Final Cut Pro, iMovie, etc. Through these software, users can easily convert, compress and encode videos.

2. Use online transcoding services: Many online transcoding services can help users convert videos into different formats, such as CloudConvert, Online-Convert, etc. These services usually support multiple video formats and encoding standards, and users only need to upload video files to complete the transcoding.

3. Use video transcoding tools: There are many specialized video converter software that can help users transcode videos, such as Format Factory, HandBrake, etc. These tools usually have rich setting options, and users can adjust video parameters according to their needs.

4. Use the transcoding function that comes with the device: Some devices (such as smartphones, tablets, etc.) come with a video transcoding function, and users can convert videos directly on the device.

In short, video transcoding is a process of converting original video data into different formats or encoding standards to adapt to different network bandwidths, different terminal processing capabilities, and different user needs. Video transcoding is of great significance in the field of digital video. It can help users play videos normally on various devices and platforms, optimize video quality and playback experience, save storage space, and improve video transmission efficiency.
