@Alex:

Have you tried making a codec by yourself? No? Shut up. You’re wrong. Reducing rounding error in intermediate steps can improve compressibility greatly. Oh, and motion compensation has everything to do with 10-bit; having a more accurate Fourier transform doesn’t help as much as not having large round-off errors accumulated from motion compensation. (Halfpel interpolation uses intermediate values with 6 more bits (i.e. 14 bits for 8-bit encoding, 16 for 10-bit encoding), which, guess what, need to be rounded off.)

10 bit 0r 8 bit?, using an 8bit you can display 256 values of intensity level on RGB now 10bits would be 1024 intensity levels computationally 10bits is 3 times more true to the source, nevertheless, as human beings I don’t think my eyes can really differentiate 1024 level of intensity or even 256. Example if I have a RGB value of 200 – 0 – 0 in 8bits would be equal to 800 – 0 – 0 in 10bits.
Now between R200 and R201 in 8 bits is the same as R800 – R804 in 10bit so in 10 bit you gain the ability to display 3 intensity levels more than in 8bit. I would really like to see a comparison between 8 and 10bit encode ans see if it’s really work it.

One time. Unsuccesfully. But I’d learnt many from it. So go suit yourself, lad.

I agree reducing rounding errors in MC can help compressibility _a bit_. At the cost of the scene quality, random noise will be introduced at FFT, poorly compressed losing some bits to the high frequencies, and then propagated as well. Only special psychovisual filter profile may help there (highpass at 8 bit level), but don’t really know if it will.

And more. If we have less quality at the FFT step, no motion compensation can regain that, because all the defects here will be propagated.

>>> Halfpel interpolation uses intermediate values with 6 more bits (i.e. 14 bits for 8-bit encoding
And there it is. Why do we need another questionable method to do that?

>>> using an 8bit you can display 256 values of intensity level on RGB now 10bits would be 1024 intensity levels
Also, the source is 8-bit. We won’t magically get 2 extra bits of quality from nowhere.

The point is:
PROs:
Questionable increase of compressibility.

CONs:
Much more CPU resources needed.
No H/W acceleration possible.
Unplayable on most players.
Unplayable on hardware players.
Questionable loss of quality.

Okay, I just won’t do that anymore. Sorry for that.

Don’t want to offend, but the Yuru Yuri has some problems. Don’t know if this is source or encode, but chroma noise is terrible as seen on the IPS 24″ LCD. May you please confirm, if this is source problem or encode problem related to the smaller file size?

  Let me fix a few things that are wrong.
  
  1. Pro’s are that it increases quality WHILE reducing filesize. 10-bit severely reduces banding and problems related to it.
  2. 8-bit to 10-bit to 8-bit has been shown to produces higher quality images than 8-bit to 8-bit to 8-bit. Being 8-bit in the first place has nothing to do with the end result. Video are also MPEG-2 at the start for TV, but it’s better to use MPEG-4 in the end.
  3. Banding is not placebo.
  
  Now here’s what I will verify.
  1. I don’t care about any of your toys. Watch it on a PC, or via a HDMI hookup.
  2. If you rely on GPU, get a better computer. I play back 720p 10-bit flawlessly on a 2.3 GHz dual core laptop.
  3. You’re seriously DLing from a BD encode group to watch on an 8″ screen of a netbook?
  4. iPad’s are like iPhones last I saw and require retarded settings like baseline profile to encode. For 3 and 4, if you want that, you’ll need a specialized re-encode group, not us.
  5. >Implying I do anything for the sake of filesize a few weeks before I release a 30 GB Macross F batch
  6. See 5.
  
  The problem is that you’re expecting these releases to be for every userbase. Nobody does that, 8-bit or not.

The difference is that with mb-tree and weight-p, it was possible to support hardware offloading for playback via driver updates and software changes. This appears not to be the case for Hi10 – they will require new hardware to play back if you don’t currently have a powerful enough CPU (and currently no hardware on the market has support).

Labelling so that people are aware of this seems to me to be a sensible idea.

1) Cuda is a programming language, not a chipset. It allows you to program shaders to
do tons of scientific physics and parallel tasks — that it couldn’t be programmed to decode Hi10 seems unlikely… case in point:

2) See http://haruhichan.com/wpblog/?p=205 — especially ‘madVR’ decoder which uses
graphics hardware to decode 10-bit
3) http://www.digital-digest.com/software/madVR.html — under change log:
‘fixed: internal decoder showed 10bit video with non-mod-4 width distorted ‘.
(i.e. it’s been working — just not for widths that didn’t divide by 4)…
Another note:
# bypasses graphics card’s video (damage) algorithms
# all work is done via GPU shaders
—-
Exactly what CUDA is for — letting you access and program the shaders to do ‘whatever’…

4) CoreAVC 3.0 currently in beta and set to come out in the next couple of weeks and the main feature of the release is 10bit. Source: doom9.org
Not sure if it will include CUDA support, but most people that use CoreAVC, usually use it for CUDA. Otherwise, FFDShow works just as well.

Also saw someone making inquiries about ‘atom’ support for HI10 in another forum, and the answer people thought was ‘soon’, as Intel wants to support Japan as a primary customer and many vids are coming out in 10-bit format now…

So, before you get all upset and have a heart attack, you might wanna check the sources of your information, cuz it seems like HW support is already available (for free — madVR = free), and other options sound like they will soon be available.

I’m noting (in closer review) some tearing and blocking (just a little) and a brightness/contrast washout issue for the first few seconds of playback using Xine, but it straightens up nicely after that. I have a feeling I’ll find a parameter I need to set to correct for this, though, after I’m through digging.

Thanks again for doing these. They are providing some enjoyable test video for Hi10p compatibility tests. It’s hard to keep good test logs when I’m laughing this much, though.

Did anyone even bother to test the effects of 10p upsampling compared to other rounding methods that don’t require on the fly downsampling overhead?

The fact that rounding/blending of information helps compressibility is nothing new, so it’s confusing to see this pushed with no comparison to methods that don’t require on-the-fly processing (like deblocking filters). It’s also confusing to see this being pushed as better quality when it’s clearly less accurate to source, though I guess this creates the perception of better quality if the source has banding issues.

David writes:

I’ve been poking around the last few days, but can’t find anywhere that really talks about this.

My question is, what metrics do you use to determine the ‘quality’ of the output? And by extension, what quality metric do you aim for to determine what settings to use for your encode?

SSIM (literal, inverse or decibals)? PSNR? Bitrate? Subjective viewing? If subjective, do you do side-by-side comparisons with the original, and if so how are comparisons evaluated? Other?

I realize CRF encoding is desirable as an “encode at this quality” parameter, yet a given CRF can produce vastly different values in the other metrics depending on source and settings, so it’s not very useful as a target metric (and in many cases is explicitly not useful).

For the highest quality encodes, what method do you use to determine transparency with the original? How does this measure vary with video resolution?

When you consider measures such as “doubling the quality” (eg: going from 0.98 to 0.99 SSIM), it’s really more like halving the number of errors. In the Hi10P analysis of the value of the number of bits used, going from 8 to 10 bits reduced roundoff errors by 75% (~4x quality), but doubling again (going to 11 bit, and then another double to 12 bit) did almost nothing to improve subjective quality. There just weren’t enough errors left by that point that halving them again made any noticeable difference.

And, given all that, what do you see changing in your target metrics as you transition to Hi10P?

I totally agree with coalgirl, that it’s his/her choice how he/she encodes, but I also agree with nINJAkECIL that there should be some kind of indication of it being Hi10p, because many of us DO use those “plastic toys” (like netbooks and nmt-s), not because they are powerful, but because of their power consumption (and ease of use) while doing effectively the same thing as my (now) midrange 4-core PC.
My PC uses >150W just to be on, while my popcornhour uses less then 20W to play a 1080p h264 movie.

Then again, it’s no big deal if I know that i can’t play it on anything but my pc or laptop. It’d just make life easier to know this beforehand even when only browsing T.T..info.

there is no point doing that. besides not supporting hi10p, standalone players and the likes have various other limitations like not supporting high@5.1 features, anything higher than an arbitrary peak or average bitrate, reframes, lack of header compression and ordered chapters for mkv containers…etc..
While it might be nice to have a MediaInfo summary alongside a release tagging it with that stuff would be insane.

As for device compatibility, hi10p is hardly anything new, players not too old or too cheap (by means of support/firmware updates) will probably soon get updates (and new devices will support it) as hi10p gets increasingly popular. if we were to wait for existing low end hardware to catch up as technology progresses, we would still be spinnign vcds today.

Also, it’s interesting that file size now doesn’t seem to matter anymore after all the nagging about “huge” files this group probably had to endure in the past.

Also, thanks a lot for this release!
