What Is Video Transcoding And Why It Is Crucial? 

Buffering has been the most cited problem by the viewers. This has come as a serious problem for all the video streaming platforms. Providing quality video streaming becomes a task in all these situations. The issue can be efficiently solved with the use of video transcoding. Transcoding is a process of decoding, reformatting, and then re-encoding the video file for smooth delivery. There is a lot to understand about transcoding. Let us dive to understand what video transcoding means, how it works, why is it important for quality experience so on.

What Does Video Transcoding Mean?

Video transcoding helps in creating multiple versions of the same file in different file sizes. Each file is made to deliver the content optimally to every user. This is meant to make the content accessible to users of different speeds. In short, it delivers videos according to the internet speed of the user. This helps in getting the best user experience to the viewers by reducing the latency and lagging of the viewers. Therefore it brings a satisfactory end-user experience to the viewers.

How Does Video Transcoding Works?

Transcoding becomes crucial for video files since video files are quite large in size. Due to the large size, files consume huge bandwidth and memory. To resolve the matter of size, codecs are used. The most common codec used for video streaming specifically OTT platforms is H.264 the available codec. All codecs work more or less similarly. These codecs help remove the unnecessary data that reduces the file size while providing a high-quality video to the viewers.

Transcoding carries forward a process of using the existing file and re-encoding it with the available codec. The first file or the master file is the best quality file of the video. Any encoded version usually encodes down the quality of the video, therefore, bringing a lower video resolution or bitrate copy. In a nutshell, video transcoding usually refers to using the master file and encoding the video quality.

How To Maximize Quality Experience?

Any viewers get a quality experience when they are delivered a video without any buffering or interruption. A negative viewing experience may lead the viewers to stop streaming and perceive your brand as unreliable. Transcoding gives one an opportunity to multi-bitrate streaming. It can help in bringing the best user experience and can build a better brand image to larger audiences.

Video Transcoding: Locally Vs Cloud-Based 

Transcoding is used in two ways i.e. locally and on a cloud. Each of them has its own pros and cons that depend on the need of the platform.

The local transcoding is a bit slower and results in multiple files that need to be uploaded and managed separately. It usually involves editing and compression software namely Adobe Premiere, Compressor, Final Cut X, etc. The software transcodes the file on your computer itself. You need to transcode the file manually and save multiple versions of the file.

On the other hand, cloud transcoding is done over the cloud. It is more or less an umbrella term that describes the encoding and transcoding happening on the cloud rather than on any equipment. If you are using a cloud-based streaming platform, you first need to upload the master file and choose the required resolution and get the transcoded file accordingly.

Conclusion

In a nutshell, transcoding makes video delivery easier for the end-users. It helps in making the video content delivery seamless to viewers with different internet speeds. In all, it helps in bringing a quality experience to the audience.

Google Releases Lyra V2: A New Audio Codec

Lyra V2- A New Audio Codec

Google has recently released a new codec named Lyra V2, a better, faster, and more versatile speech Codec. The architecture of the new Lyra V2 brings scalable bitrate capabilities, provides better performance, provides wider platform support and generates a higher audio quality. With the release of Lyra V2, Google is trying to evolve with the community. 

The Architecture Of Lyra V2

The latest release of the Lyra V2 is based on SoundStream, an end-to-end neutral audio codec. The architecture of the latest audio codec includes a residual vector quantizer Or RVQ which is present before and after the channel of transmission. RVQ quantizes the encoded content into a bit stream and thereafter reconstructs it at the decoder side. 

This integration of RVQ into the codec infrastructure allows changing the bitrate of Lyra V2 at any time just by selecting the number of quantizers to use. To generate higher-quality audio more quantizers are used. This codec uses three different bitrates which include 3.2 kbps, 6 kbps, and 9.2 kbps which enables the developers to choose bitrates suitable for network conditions and other requirements. With this new architecture, the delay in the audio delivery is reduced from 100 ms from the previous version. It is most comparable to the most used codec Opus which has an approximate delay of 26.5 ms, 46.5 ms, and 66.5 ms.

This latest audio codec released by Google has the ability to encode and decode audio by 5x than the previous version. Apart from the speed and performance, the quality of the audio generated by this new audio codec has also improved. This model of V2 is exported in TensorFlow Lite. All this makes V2 a great alternative to other state-of-the-art audio codecs. It has the ability to be connected with more devices in bandwidth-constrained environments, making it an appropriate choice for higher audio quality requirements.
