Details as follows:. These are the results:. I compiled a bit version both x and x A few notes on it:. Get it installed you can sit it beside your regular version if you want. Unzip the handbrake-libs-mac. Those are the library files that you need to install on your system. A few images below to help click for larger versions :. These instructions are primarily for Ubuntu, though other similar debian-based distros should work.

If NOT on Ubuntu but are on another Debian-based distro, you can still manually download one of the packages in. Extract them, and you should have 5. Now you just have to copy them to your library.

For example:. Assuming that was successful, try firing up HandBrake. Note that Lazarus also came across a GUI solution in the comments below which you can jump to here: comment The bit CLI version I built can be grabbed from here: handbrake-clibit-windows.

It supports both bit x, and bit x They go in the same directory as the HandBrake Nightly. Only try these libraries on a newer version. At the beginning I mentioned that it might be a good idea to scroll waaaaay down before someone goes off and encodes their entire library at bit HEVC. Why NOT to use bit and bit.

My best advice would be to run your own test encodes back-to-back and decide for yourself. Details as follows: If using Windowsunder the Windows section below I have a link to the Handbrake forums where they provide updated libraries. Use that! If using Mac OSthe original and newer bit-only builds should work.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I do a lot of HEVC encoding and what I've read is 10bit is always better than 8bit, even from an 8bit sourcebecause it avoids rounding errors. Is that true? I can answer your first question. In my experience using handbrake increasing the bit depth increases the file size but not by much.

However, lowering the CRF is what causes significantly larger files. I encoded several times the same source with different settings to see what I'd get, so for a random source of 1. Sign up to join this community. The best answers are voted up and rise to the top.

Fallen Fallen 81 1 1 gold badge 1 1 silver badge 2 2 bronze badges. Well, bit has 4 times the resolution of 8-bit, so yes, rounding errors will be smaller. Assuming you are encoding for end use, the benefit will depend on the source material and the display medium.

10bit vs 8bit colour. When NOT to use 8bit, and why.

The same is true for bit, in principle, but the extra resolution over bit shouldn't be significant for normal end-use.Return to : Feature Stories. Today's increasingly demanding applications, such as Ultra-HD TV, wireless display, and high quality video capture are driving the need for new video encoding and decoding technologies.

With the increasing availability of OLED displays and 10 bit monitors, which offer a wider color range, consumers are demanding higher color fidelity than ever before.

It is a direct successor to the highly popular H. Several demonstrations of HEVC are in evidence across the industry. For the next generation of products, hardware-based HEVC decode and encode will be necessary to drive the requisite performance while keeping power consumption to a minimum. HEVC divides a frame into small blocks referred to as "CU" — or "coding units" and the prediction and transformation coding of the images is conducted within each CU.

This larger block size allows HEVC to achieve higher compression or higher resolution and improve parallel processing efficiency compared to H. Today, designing a video coding standard for both mobile and consumer devices is primarily aimed at achieving the highest coding efficiency possible.

This translates into an ability to encode ordecode video at the lowest possible bitrate while maintaining a defined level of video quality. Several studies have compared the coding efficiency of the H.

These comparisons usually involve video encoding done for a range of application use-cases live entertainment, video conferencing, films, etc. Perhaps the key takeaway when thinking about H. Indeed the quality of HEVC video is determined by how complex and feature-rich the encoder is.

Encoder quality dependencies include the motion search algorithm and range, tool set implementation and rate control algorithm. These solutions are a reasonable first step towards implementing some relevant use cases for existing platforms that do not have dedicated hardware; HEVC at p is one of a few examples.

However, hardware video trans coding brings significant advantages and features bit color, YCbCr resolutions, etc. If not designed carefully, such a core might drive the overall system power consumption to extremes.

Independent tests, for example, have shown that PowerVR video processors VPUs are not only lower power but much faster at transcoding video streams.

A recent example from Anandtech, shown in Figure 3, compares a number of existing platforms encoding a standard video stream.

Interesting alternatives to H. InGoogle launched an experimental version of YouTube that used the built-in multimedia capabilities of HTML5-based apps to stream videos.

Consequently, the WebM Project was assembled and tasked with developing a new format for video and audio compression. Their work resulted in VP8, an open-source alternative to existing video standards.Just dove into ripping my first 4K bluray.

Getting into the encoding process with Handbrake, I have been digging around the internet trying to find an answer to the subject line question… is the only advantage to H just more compression without loss of quality? More importantly, can you use either or to preserve HDR? Anyone have any idea? I hope H is ok to preserve everything because the time it takes to encode H with Handbrake is ridiculous! This was happening way back when I first started my regular BluRay ripping of my collection.

I use it for all my media due to two advantages - smaller file size and consequently less bandwidth needed for streaming, without sacrificing on quality.

The only negatives are that it is significantly more CPU intensive, but I think a better more modern codec, and some old devices have trouble and have to transcode H. In terms of HDR, I run the nightly version of that software. It gives you the option for bit and bit H. It also has a bit option for H. The color depth profiles for those different bit rates are significantly different.

Could you give me a little insight into how I would go about getting those extra options? You can select the appropriate version for your system, and it can be installed along side the stable build. You can find the video codec options that I mentioned before in the usual spot in HB. Let me know if you figure it out. You are going about this the wrong way. This includes both video and the audio that goes with it.

At that point you can just remux. I generally go X, highest quality ie longest one time conversion time5. General General Discussions. I am not an expert by any means, but this is what I have learned.Before you start posting please read the forum rules.

By posting to this forum you agree to abide by the rules. User Name Remember Me? A month ago, I was told to enable 10bit mode, without being asked if my input footage was 8bit. Is there a reason to encode in 10bit even if the input footage is 8bit? Your input doesn't matter much what bit depth it has 8 or 10 do note that a lot of gear still doesn't support 10 bit yet, computers excluded.

The Emergence of H.265 (HEVC) and 10-Bit Color Formats

If you have a HW decoder that can deal with 10 bit, displaying it on an 8 bit display like a TV is not an issue. If your TV is 10 bit, even better.

I did a test on a 8 bit TV-episode encoded with x 10 bit Preset Medium CRF 19 and compared it to a 8 bit encoding same preset and crf and I couldnt see any difference, but the file size came out mb bigger for the 10 bit encode.

Is there a video Youtube? There are actually some video blogs that will point you in the direction you are looking. You can quickly google something like benefits of 10 bit x encoding. What you will be looking for is things that you can see only in frame by frame comparisons really, and in areas where there would normally be lots of dithering, like clouds and leaves and backgrounds.

Information that would easily be lost. The 10bit profile makes it less objectionable when dealing with gradients. Originally Posted by GZZ. Originally Posted by Sparktank.

10/12-bit x265 encoding with Handbrake

You are set to go. Additionally, you will need much more computing power to decode x files because most of the processing are done by CPU and not video hardware Bye! Raspberry Pi. Thanks to Matt Gadient! Be sure to check it out! The same problem comes when using 10 or bits videos, there are not many devices that play those videos. Furthermore, it takes so much RAM to encode those videos. Matt Gadient also made BITs comparison page between 8, 10 and 12 bit encodes.

Compared to x, encoding x files requires a lot of processing power to encode which will provide you with a smaller file with amazing quality.

Overall, the only benefit with x is smaller size. With the price of storage devices getting lower, i would recommend you guys to just stick with x when trying to encode and stick with x releases as to save internet bandwidth. LY A medical student with an endless curiosity. Why x, and not x? Smaller size, while preserving quality i. When to use bit or bit or not? Smaller size with bit The same problem comes when using 10 or bits videos, there are not many devices that play those videos.

Still waiting for that hdmi vs usb breakdown Best wishes, Happy Holidays. Hey there sk16! Can't say I'm much of a video guy either Just having fun with the tech and getting familiar with what's out there and the potential for us consumers.

So, any ideas what you'd like to see when it comes to HDMI vs. Back in the days of analogue TV, broadcasting engineers in Europe made the lower half of their "colour bars" line-up screen an area of solid red. This was done because the human eye is most sensitive to small changes such as those caused by quadruplex video tape artifacts at the red end of the visible spectrum. It would be interesting to see how the results you obtained compare to a similar video taken of say, a red flag waving in a gentle breeze.

Interesting comment Roderick. I assume this is chroma subsampling you're referring to? The AVC P file from the phone is compressed so there will be subsampling of Cb and Cr to every 2 lines both horizontally and vertically Actually, I was referring to the simple fact that the human eye is most sensitive to small changes in hue or saturation at the red end of the spectrum. That is all.

Good point. So we're I think both on the same wavelength Red and blue do both tend to be sacrificed in resolution when it comes to chroma subsampling but red can be more noticeable in the compression. I'll see if I can find a good scene with gradations of red to check out In other words, and all else equal, if an audiophile had a choice in transmitting an audio file from computer to dac, which should they choose?

Thanks, Happy New Year. Would you mind making the files or at least the AVC bit file available for download? I can't find any files in that format to test. It is actually a great and useful piece of information. I am glad that you shared this helpful information with us. Please keep us informed like this. Thank you for sharing.
