Hi!
Perhaps it is already possible to create a theme Daala vs HEVC.
There is a demo booth with pictures > http://people.xiph.org/~xiphmont/demo/daala/update1-tool2b.shtml
On the example"Pont de Quebec at Night" - this Daala very strongly presses the small details/stars and edges noisy + what that faint blue glow is present in almost all the photographs (similar to the effect of field).

Aside from being totally offtopic:
For me Daala is a marketing stunt unless I there's a encoder (which I can use with pipe input) and a directshow decoder which can decode the content.
Then it would start to get interesting and one would still need a container&which would support Daala.
(+ looking at how it performs on the Cloisfest image, it would probably a bad choice of codec for the anime crowd atm.)users currently on my ignore list: deadrats, Stears555 -

@jagabo: why not select 'original image' on one side?

Daala (master as of April 30, 2014), VP8, x264, and x265 at identical output size
- VP8 (and 9) got a really bad 2pass implementation, so hitting a bit rate seems to be more like a game of luck
- x264s hitting a bit rate normally works in an acceptable manor, but to get identical output size you still would probably need more than one encode.
- getting x265 and Daala (which both have no real 2pass/precise rate control) to hit one target
-> LOL, sounds like a silly dream.users currently on my ignore list: deadrats, Stears555 -
Cloisfest image - it is seen as texture floats on the neighboring plot (need adjustment).
Will be useful filter "Chrome smoother" for decoder.
And a faint blue glow can be associated with Chroma From Luma Prediction > http://people.xiph.org/~xiphmont/demo/daala/demo4.shtml -

I think I'm gonna faint. david55 actually posted a comparison where it's possible to actually see a real difference in the photos instead of the usual "this is one millionth worse than the other photo" stuff we usually get where 99% of human beings can't see any difference or don't care if they do see it because the difference is so small.
Yes, jagabo, we all know that YOU do see things differently from everybody else. You're in the 1% camp. -
When there aren't very obvious differences you have to look at the less obvious differences. It's not my fault people are posting relatively high bitrate samples where the differences are tiny. I'd prefer to see moderate bitrate encodings where the faults are clearer -- because that's where these codecs will be used. The samples in post 13 are too far gone to be of any use.
Personally, I'm not interested in h.265 or Daala at this point. Until I have devices that play them it's all academic to me. -

Zopo 980+ uses the processor МТК6592 - supports hardware decoding of HEVC_1080P@30fps.

Oh, it even has hardware decoding support for hevc, nice.

@david55: just judging by the name it looks more like 'parkjoy' than the clips belonging to the last two images Cornucopia was looking for

This algorithm may allow the excess savings bitrate for video communication.
Still give indulgence per a brand new compression technology (encode / decode) -
I installed the codecs Daala. For me, these are the codecs that are currently teach humility. WQHD file i420 8bit 60fps, 300 frames processed to 1h 36min. The result of a visual film: film is faded and lost clarity.
Asked parameters were equivalent to the size of the file X265 20000kbps:
PHP Code:ffmpeg.exe -f rawvideo -pix_fmt yuv420p10le -s 3840x2160 -r 120.000 -i "3840x2160_120fps_420_10bit_YUV.yuv" -s 3840x2160 -r 60.000 -f yuv4mpegpipe -pix_fmt yuv420p - | daalaenc.exe - -v 100 -k 60 -o "3840x2160_60fps_420_8bit.ogm"

Send us your comments and suggestions for improvement.
Well still alpha. Affirmative specification will only appear at the end of the year (Go experiments).
They started from scratch, while HEVC continues from AVC.
