However, higher thread counts produced more transientquality issues than lower settings in the ten clips that I tested. Even for very aggressive VOD encoding settings, the impact of the threads setting on overall quality is minimal.If you’re using FFmpeg as a live encoder, or use an encoder like OBS that lets you customize the FFmpeg commands, it’s worth experimenting with different threads values to potentially increase quality. The overall quality impact in real-time capture applications was more significant than for VOD.The threads command impacts performance, overall quality, and transient quality.How the FFmpeg Threads Command Impacts Qualityįor those who don’t relish the intellectual exercise of testing and scoring, here’s the net/net.How the FFmpeg Threads Command Impacts Performance.What Does FFmpeg Do if You Don’t Specify a Threads Value?.What Does the FFmpeg Threads Command Do?.How does the FFmpeg threads setting impact quality?.

So hundreds of encodes and three days later, here are the questions I will answer.

Specifically many streamers are buying 8 core/16 thread CPUs to encode as a standalone client capturing information from a video capture device.” I had an article on FFmpeg due on the editorial schedule so I decided to run a few tests and see, checking VOD and live.Īs we all have learned too many times, there are no simple questions when it comes to encoding. So, I received an email from an acquaintance that read, “I was curious if there is actually any benefit to a “threads=” type custom command in x264. Don’t just learn FFmpeg become an expert in video compression. The level of testing and analysis detailed here is consistent with the instruction in my book, Learn to Produce Videos with FFmpeg In 30 Minutes or Less ($34.95), and my course, FFmpeg for Adaptive Bitrate Production ($29.95) (which includes a PDF copy of the book). This article details how the FFmpeg threads command impacts performance, overall quality, and transient quality for live and VOD encoding.
