Intel Kaby Lake h.265 Encoding Confusion

Fail Complex · Jul 9, 2016

I read the news of Kaby Lake can encode h.265 10-bit. But I was wondering if encoding can be done real-time? You know real-time for Streaming?

Also how big can the resolution be for encoding? And can it be done at 60 FPS? 4K@60FPS at least?

You can already encoded h.265, handbrake already has a setting to encode video in h.265. Encoding isn't something a cpu needs to support, it's a pure process operation. Now what news you read probably refers to the speed at which it can encode at such a codex, over the years intel has found ways to improve apon the way its chips encode video.

Really? Just Pure Process Operation??? Have you heard of the Vega-3300? It's say it can be able to encode 4K@60FPS in Real-Time. It doesn't make sense it's only 15 W of power from the Vega-3300 but if was CPU it's 130 Watts and the CPU gets bogged down and can't encode in real-time. On the 2nd Link I think they talk about 'processing operation'? on the Vega-3300? But the Vega-3300 PCIE Added something 'four channels'? to be able to encode real-time. I was wondering if AMD Zen or Kaby Lake implementing something like that to the Vega-3300.

Your response in can encode h.265. Is it real-time? Real-time for streaming?

Hmm... interesting, never heard of a Vega-3300 hardware encoder like that, but from first inspection it appears to require software that uses its own api. What I was talking about, and what I assume you were talking about was just encoding a video as h.265. Handbrake can do that h.265 but frames done every second depends on how much pure processing power you have, its well above real time, atleast when I do my encoding its in the older h.264 @ 1080p. I can do a 3hr video in 45 min, with a quality of rf 18. On an older i7 3770k @ 4.2ghz.

It doesn't feel like it, to me think the Vega-3300 is more like the HD60 Pro PCIE Card. https://www.elgato.com/en/gaming/game-capture-hd60-pro . The Vega-3300 can also do H.264 as well.

Really you are able to do H.265 real-time on your system? That's weird I read on the OBS-Studio on the forum, no system on streamers is able to encode h.265 in real-time that's why OBS Studio hasn't implement it yet.

Real time would take forever, are we even talking about the same thing? If a 3 hour video took me 3 hours to encode I would lose my mind. 1080p H.264 that's 3 hours takes me 45 min.
