Get a cheap Intel Arc GPU instead like the SPARKLE Intel Arc A310 or SPARKLE Intel Arc A380 ELF 6GB.
- i80and 2y agoThis is true for the AOM encoder, but SVT-AV1 is actually pretty darn fast in my experience!

- uyzstvqs 2y agoTrue. From my testing SVT-AV1 is about 1.4x faster than x265, and about 540x faster than the original AOM encoder.
- SR2Z 2y agolibaom is slow because it's fundamentally a research product - the folks hacking on it are mostly concerned with the workload of encoding a basket of twenty short clips and demonstrating a tradeoff between Bjontegaard scores and increased encode time, and much less on holistically making a usable encoder. Source: wrote part of the AV2 spec and traded off a 0.3% improvement in compression for a 1% increase in encode time
- ksec 2y agoSo where is AV2? And 0.3% improvement for 1% increase in encode is pretty damn good.
- andrewstuart 2y agoThe benchmarks below show you need very powerful machines to get software encoding up to the sort of frame rates that hardware encoding will give you even on low end CPU/GPU combinations. Even given the numbers in the benchmarks below I think the cheapest of Intel cards are going to make alot more sense than using the CPU of some honking great machine to do software av1 conversions. As usual with benchmarks it takes some effort to understand what they mean. Trying to get some tangible information into it with minimal effort: Some benchmarks - use the dropdown to choose different preset/resolution combinations.

- rasz 2y agoAlmost all Hardwave video encoders come with the assumption of running in real time, thus sacrifice of quality for speed. How much? Sometimes as much as switching to previous gen codec https://goughlui.com/2023/12/24/video-codec-round-up-2023-part-0-motivation-methodology-limitations/ https://goughlui.com/2023/12/24/video-codec-round-up-2023-pa...
