Based on libaom, carnival Provides developers with a powerful AV1 encoder designed to provide faster processing and a variety of customization options for quick and easy encoding.

The encoder is available as a console application and Windows SDK. In the following, we will describe some of the most important options that can be used as extra arguments to the command prompt tool. To see all descriptions of all parameters described in detail, you can run the “–fullhelp” option.

Single-pass and multi-pass encoding

rav1e has inter, intra and toggle frames with customizable keyframe intervals. You can easily set the thread pool size and specify the number of tile rows, columns and tiles. Pixel ranges are customizable, as are frame rates, bit rates, and timescales.

rav1e has a constant quantizer and target bitrate encoding mode, with single-pass and multi-pass encoding. In the first pass of a two-pass encoding operation, data is saved to the specified file in preparation for subsequent passes. In the second pass, the input data is the file previously saved in the first pass.

Find the perfect balance between speed and quality

The processing speed level can be changed from o to 10 to any value convenient for you, but keep in mind that the maximum and minimum values ​​are generally not recommended. The lower the speed (values ​​closer to 0), the higher the quality. You can also adjust the quality by choosing between PSNR and Phychovisual.

The number of frames to be encoded can be limited. rav1e supports 8-bit, 10-bit and 12-bit depth color with various chroma sampling options.

Console based AV1 encoder

rav1e brings a console-based AV1 video encoder with extensive customizable options to help you process video files at high speed. With various prediction and encoding modes, customizable parameters and still picture mode, it provides a faster encoder for AV1 video, and thanks to its console-based interface, it can also be integrated into your own applications.
