The Basic Features of VVenC
If you are a CG artist, VVenC may be the best choice for you. It is an open source video encoding system that features many features, including Rate control, Subjective quality optimization, Multi-threading, and Open source. It is recommended that you test this version before investing in it. However, you must keep in mind that this version is still in development and its functionality is limited. This article will explain the basic features of VVenC and the pros and cons of each.
Open source encoder
An open source encoder for VVC is a free video codec, and a new version has just been released. This new version aims to achieve higher running speeds, support for multiple threading, Single/Two-stage code control, and subjective quality optimization. The following are some of the key features of VVenC. If you’d like to try it out, download the latest release and get started.
The VVenC encoder supports the Main10-4.4:4 configuration file, which is used for processing slice code. It does not support 2 way weighted prediction, but it does support Chinese. It also supports YUV formats, and future versions will support them as well. To download the latest version, visit the VVC website. You can read a detailed review of this open source encoder for vvenc on its website.
Open source encoders are freely available, and many of them support a variety of video compression standards. Open source video encoders allow developers to test a variety of methods before deciding on a specific implementation. This is useful in determining the best video compression method for a particular use case. You can also try VVenC if you’re unsure whether this standard is right for your needs.
As a result, it’s important to check out the royalty rate of VVC before deciding on a final version. It will take some time for a VVC player to reach a critical mass, but it’s certainly worth a look for content publishers. In the meantime, the cost of bandwidth will make it harder to justify a new codec. However, it’s still important to analyze the advantages of this technology in your video workflow.
Rate control
One of the most significant improvements that VVenC brings is the ability to use rate control to increase bit rate. By making small adjustments to the encoder, the user can raise the bit rate from 2.5 to 7.1 or 7.4 kbytes. Typically, this mode is used for video coding, but it can also be used for audio encoding. There are some disadvantages to this mode, however.
It is also possible to adjust rate while transcoding. This feature is enabled via the VVenC source code. Currently, VVenC supports the Main10-4:4:4 configuration file, which is used to process slice code. This version also supports Chinese input and output and is not limited to the US or UK. The upcoming 1.1.2 version will include support for YUV. The VVenC encoder also features a streamlined user interface and an easier-to-use graphical user interface.
Besides rate control, this version also includes the JVET CTC, which uses a sequence-specific configuration to optimize bit allocation. The optimization process has been implemented on the VVC Test Model 3.0. The improved speed and accuracy is achieved through proper bit allocation. A detailed comparison of these two versions of the software shows that it can save 1.03% of BD-Rate while achieving higher control accuracy. You can download the latest release here:
The latest version of the VVenC video codec includes a novel rate control algorithm based on rate-distortion characteristics. This algorithm incorporates a composite Cauchy distribution to provide higher accuracy than other distributions. Furthermore, the rate control algorithm also incorporates theoretically derived models to model the dependency between levels of frames. This approach improves both accuracy and performance of rate control. When compared to traditional least-squares algorithms, XPSNR is more accurate than the previous version.
The VVC standard was created with a variety of use cases in mind. It provides wide support for a range of content types, including high-resolution video. The open source VVenC encoder implementation is aimed at providing a faster runtime than the reference software. Rate control, multiple-threading, and subjective quality optimizations are among its major features. This encoder is optimized for random-access high-resolution video encoding. Moreover, it can also be configured for use in different content types and configurations.
Subjective quality optimization
In addition to the usual objective tests, VVenC incorporates a xPSNR-based subjective quality optimization. This metric overcomes the limited correlation between perceived and real distortions by utilizing a simplified model of the human visual system. It also implements local quantization parameter adaptations (QPA), which improve rate control accuracy and performance. We conducted three subjective experiment sessions using the test sequences in each of the three resolution groups.
Unlike HEVC, the VVC codec can achieve a VTM-level of subjective quality by reducing bit-rates by as much as 40% for HD and 50% for UHD. Objective and subjective quality metrics were also employed for the adaptive bit rate test case. The results indicate that the new codecs have improved the video quality of the encoded content. The algorithm can also support multithreaded operation and run-time scaling.
Open source encoders can also benefit from the VVC standard. Compared to VVC reference software, VVenC can run faster. It also supports multiple threading, rate control, and subjective quality optimization. It can also be configured for different content types and configurations. However, this does not necessarily mean that VVenC is faster than VVC. Rather, it’s a more flexible and extensible standard that enables a wide range of use cases.
Versatile Video Coding is a new international video coding standard. It is scheduled for finalization in July 2020. Its main goal is to offer significant bit-rate reductions. Its predecessor, High Efficiency Video Coding (HEVC), was not finalized until July 2020. In addition, VVC reference software has reported a 40% bit-rate reduction, compared to HEVC reference software, implying a 9x encoding and decoding speed.
Multi-threading
Multi-threading is a common programming practice that separates concurrent from parallel processing. In the context of spreadsheets, for example, it is common for the file to be saved more than once during its development. In this case, multiple threads are created and each thread takes care of different activities. In general, threading is an efficient way to speed up a program. Here are some common examples of multi-threading in Vvenc.
For example, if you are trying to make a comparison between two pairs of images using a single image, you can use mutex. This method prevents multiple threads from accessing the same piece of data simultaneously. For example, if one thread has the token A, the other thread cannot. Then, each thread must wait for the other to release the token. The mutex is a synchronization mechanism that prevents the simultaneous access of two threads to a single object.
VVenC supports low-complexity quantization, which is based on a simplified model of the human visual system. In addition, it uses XPSNR and MS-SSIMYUV as subjective video quality measures. Adaptive resolution is another key feature of VVenC. These are just a few of the features of this multi-threaded library. You may want to check it out for yourself!
Another popular feature of VVenC is its ability to support multiple threads at the same time. Unlike traditional multitasking, which involves one thread executing until it is blocked by a longlatency event, multi-threaded acceleration allows for high-speed execution. This feature is referred to as coarse-grained multitasking. If you’re looking for an open source encoder that provides multi-threaded acceleration, it is the right one for you.
The multithreaded approach allows applications to take advantage of the power of several processors. It also enables multiple threads to share memory, which allows the program to take advantage of more of the CPU. This is especially important for AI, which relies on human decision-making. Human reaction time is 0.25 seconds, while AI must make decisions in as little as tenths of a second. To make these decisions in time, multithreading in C is the ideal solution.
