![]() ![]() There are plenty of other software encoders like the industry used ATEME TITAN File for UHD blu-rays or other open source encoders like Turing codec or kvazaar, but because of their lack of inclusion in standard tools like FFmpeg, they are overlooked. The workhorse of the HEVC software encoding world is x265. Please excuse the poor artwork, Clara wasn’t available this week so I had to do it myself! Use case over metrics Just as it’s futile to compare the track capabilities of a supercar to the towing capacity of a pickup truck, we are about to venture into said territory with these encoders. In today’s case, it takes a AMD GPU with VCN support to use the features we want to test.Īpples and oranges are both fruit, sports cars and pickup trucks are both vehicles, and software and hardware encoders both transcode videos. In the other corner, Hardware encoders rely on specific physical hardware components to exist in a system to use them to accelerate their transcoding. Doesn’t matter if it’s an Intel i7, an AMD 5900x or even on your phone’s ARM based CPU. Software encoders are coded to run on any general purpose CPU. VMAF – Netflix’s video quality metric used to compare encoded video to source’s quality.HDR10 – A set of metadata presented alongside the video to give the display additional details.HEVC / H.265 – High Efficiency Video Coding – The videos codec we will use that supports HDR10.AMF – Advanced Media Framework – AMD’s code and tools for developers to work with VCE / VCN.VCN – Video Core Next – AMD’s new name for GPU hardware encoders (VCE / VCN used interchangeably).VCE – Video Coding Engine – AMD’s early name for its built in encoding hardware.This use case is not usually covered in benchmarks and tests I have seen, and is more of the interest to those who have seen my previous posts on Encoding UHD HDR10 videos but may want to hardware accelerate it. Note: I will only be comparing HEVC/H.265 10-bit HDR10 videos (both source and output). ![]() To that end, I will present my own take on the current “war” between software and hardware encoders, then go into quick details of how to best use AMD GPUs for encoding for video archival with FastFlix. It’s 2021 and there still isn’t a lot of good info about AMD’s VCN hardware encoder for consumers. ![]()
