![]() In general, shouldn't your encoding process be tuned towards the best visual results rather than using up all the threads from your leet CPU? Encoding an old DVD won't scale very well no matter what you try to do to it, but encoding a 4k video will. The number of threads involved is dependent on the codec and the source material. I considered a Threadripper system when I upgraded to X299 but early Handbrake results from reviews weren't promising so I went with Skylake X instead. ![]() I have a different profile I use to extract more picture quality from lower quality source material but it sounds like you're looking for more speed now so those settings won't help. If you know what the "magic" switch is to get 80% use out of 16 core please let me know.Įncoding speed is affected by numerous factors so I can't guarantee that my settings will work for you, but you can give them a shot and see if you like the results. mpgs to x264.mp4s so not a demanding job. On my 6 core, x264 and a HD file can sit at 95-100% for one pass. Have not tried HEVC on the threadripper yet. That is interesting, on my first gen 16 core threadripper, x264 would only use 30 something %. Add all the right unseeable positive tweaks together and maybe I could see an improvement. Wish there was a program that could analyze the video so I could KNOW that this tweak or that tweak made a positive difference. It is frustrating to change settings and not see any difference. I've played with it and have just stuck with my old two pass method. VideoReDo seems to recommend the one pass CRF now. Is that true or is a two pass process still the best way to encode the video either for quality or performance? I've seen some online sources saying that's an older methodolgy that's been replaced by just doing everything in one pass. My question is about the first pass/second pass operation. No problem railing my cores but I'm doing it on a quad core so that's not as hard to do. ![]() Apple's AV1 plans are also murky-the company is a member of the AOMedia group and some rudimentary AV1 support has appeared i n its developer documentation recently, but hardware-accelerated AV1 decoding and encoding either isn't supported or hasn't been enabled in its most recent Apple Silicon chips.In the reencoding of drone footage I've been doing recently I've been using x265 via an ffmpeg interface. Roku supports AV1 decoding in some of its higher-end streaming devices, but allegedly pushed back against Google when the company tried to force Roku to support AV1 decoding across its entire lineup. HEVC's main benefit over AV1 as of this writing is that it enjoys much wider support than AV1 across many generations of hardware from most major manufacturers. Unlike HEVC, support for the AV1 codec can be added to just about anything without paying royalties. Like the H.265/HEVC codec, AV1 enables much more efficient video compression than the old H.264 codec, allowing for streaming of 4K and HDR video without requiring a massive increase in bandwidth relative to 1080p video. AV1 is an open-source video codec developed by the Alliance for Open Media, a group that includes heavy industry hitters like Google, Netflix, Amazon, Intel, and Microsoft.
