QUICK COMPARE: AVC vs. HEVC, 8-bit vs. 10-bit Video Encoding

As I mentioned in the last blog post on HEVC encoding in response to "Unknown" in the comments, I do believe there are potential subtle benefits to the use of the 10-bit x265 encoder in Handbrake even with an 8-bit video source. I figured I'll run a very quick test to show what I've seen...

MUSINGS: End of 2016 - Video Encoding (HEVC 10-bits, the HDR "Trinity"), Multichannel Streaming, and Other Thoughts...

For those of you into video, I suspect you're already very excited about the "next generation" H.265/HEVC encoding format. About a year back, I already made mention of the impressive results I was seeing with playback of HEVC on the Skylake HTPC I was putting together. A year down the road, we see the ongoing development of software harnessing the power of the new encoding technique - even lower bitrate for very high quality output.

As we say goodbye to 2016, I thought I'd just "shoot the breeze" a bit and meander down some related topics. Let's talk about video encoding, what I've been doing, what I've found useful/interesting, and some speculation of what I think would be in the not too distant future as it applies to high dynamic range (HDR) video...

MEASUREMENTS: Yamaha RX-V781 Receiver (a look at the pre-out quality)

With the upgrade recently to a 4K TV, it was alas also time to upgrade the surround receiver system I was using. A number of years ago, I bought a used Onkyo TX-NR1009 which I wrote about. It has served me reasonably well over the last few years but not without some issues. The most bothersome was the fact that the HDMI board died last year and it had to be sent back to Onkyo for a board replacement. Thankfully, despite the machine being released around 2011, Onkyo still honored the repair as apparently this is a common problem acknowledged by the company. Not good that the product was defective due to an engineering oversight (soldering & overheating issues), but at least the company "manned up" to the problem.

These days, to make full use of the surround sound system connected to a full-featured 4K TV, the best way is to upgrade the receiver to be compatible with the latest HDMI 2.0 specification with allowance for 4K/UHD @ 60Hz, HDCP 2.2 copy protection compatibility, as well as passing through the full video signal - including full color information (Rec. 2020/BT.2020 and HDR). (For those new to this kind of AV talk, you might want to review the 4K tech article from a few months back.)

Unfortunately, the Onkyo was only good to HDMI 1.4. It was time to upgrade to one of the new receivers... And this is what I found on sale locally:

It's a new model year 2016 Yamaha RX-V781 (current price ~US$700).
