Question / Help 4790k QuickSync @ 810@60fps/6000bitrate vs....

[Christopher Baker]

Hi Guys,

I've been streaming for about 4 years for a long time we've been using software x264 encoder for obvious reasons that it produces a nicer image and we've been doing that for 720@60fps/3000 I'm wondering now with twitch allowing up to 6,000 bitrates (yes, I'm partnered not affiliated, actual partner) I'm wondering what people opinions are on this...

I'm trialling running 810@60fps/6000 using Intel QuickSync hardware encoder, I know the image is actually in fact not as good as the x264 software encoder but the CPU loves me a lot more because of it (and so doesn't my gaming), my question is though even though the stream runs fine but, what is the actual limits of QuickSync? At which point do things go bad? What am I looking out for as a result of the change?

I did find a benchmark post here on x264 vs NVENC vs QuickSync but it was based on 1080@60fps and 4500bitrate as max, not my intended 6000bitrate.

Thanks for any help guys!

The major difference between x264 and any of the hardware encoders is that you need significantly more bitrate for similar quality at the same resolution/fps settings.

As there's far too many factors to take into account that affect what settings you would use, your best bet is to just continue testing and find out what works best for you.
