At 79.5MB their 'DivX 10.1 4K Beta' application is pretty big...

A new beta has been released concerning their command line tool...

Quote:
What's new:

Improved encoding efficiency
New options:
-aqo [1-4] specifies one of the 4 encoding modes: 1 - fastest, 2 - balanced (default) 3 - higher quality (experimental) 4- highest quality (experimental)
-F turns off scene change detection, results in fixed intervals between keyframes
--no-wpp turns off Wavefront Parallel Processing
--start [frame_number] allows encoding from [frame_number] frame


Known issues:
-aqo 3 and -aqo 4 sometimes result in a crash when encoding 4K contents.

Any test samples please?

It's too slow on my machine.

Very interesting.

Well I read that:
http://labs.divx.com/node/127941

really interessing test for these reasons:

1) first at all, DivX labs use x264 for H264 codec reference. why not use their own H264 codec? DivXInc admit just here that the x264 codec is better than their own H264 implementation codec ...

2) For this test DivXInc use "1 pass bitrate" crappy and useless encoding Rate Control mode. The conclusion is just that 1 pass bitrate method for DivX HEVC is really better than the unoptimized x265 1 pass bitrate mode. In my test x265 in crf mode produce really better quality than DivX HEVC in 1 pass bitrate mode and by far.

3) The DivX HEVC codec is certainely a good codec but only "1 pass bitrate" mode is accessible. Impossible to make encoding even with simple 1 pass at fix quantizer. For me at this time DivX HEVC codec is useless just because the rate control mode is crappy.

These results don't match our x265 test results. DivX used a build of x265 from 2 weeks ago, before we optimized our presets. x265's speed and efficiency is much better than what is shown in these graphs.

From ftp://ftp.kw.bbc.co.uk/hevc/hm-11.0-...s__hm-10.0.xls the HM 11 encoder results for RA-Main should be...
Bitrate Global PSNR
17,370.83 40.46
6,017.99 38.80
2,811.22 37.03
1,475.79 35.26
Note that Global PSNR = (6*YPSNR + UPSNR + VPSNR) / 8
If you simply take an average of Y, U and V PSNR, your quality will appear to be better than it is.

No worries. We'll be happy to repeat these tests using exactly the same settings as the DivX team suggests. It looks like it will take a while (on a Core i74700HQ with a RAMdisk)...

We can't test the high quality data point with DivX...
DivX265_1.1.18 --input d:\BasketballDrive_1920x1080_50.yuv -s 1920x1080 -br 17371 -I 5 -n 500 -aqo 4 -o d:\DivX41.hevc
Value is outside DivX HEVC Profile: Bitrate. Must not exceed 12000
For help: DivX265_1 -h
OK... now we're running...
>DivX265_1.1.18 --input D:\BasketballDrive_1920x1080_50.yuv -s 1920x1080 -br 6018 -I 5 -n 500 -aqo 4 -o d:\DivX42.hevc
0:27:56 Frame 290 of 500 encoded @ 0.17 fps
And then, it crashed, blaming the user...

btw. DivX Converter does come with a command line encoder named 'DivXEngine' (inside the 'DivX Transcode Engine'-folder):
Code:
Usage:
DivXEngine <options>
-i <input media file(s)> : set input media file(s)
-o <output media file> : set output media file
[-v <video bitrate (kbps)>] : set video bitrate, don't use with -f option
[-a <audio bitrate (kbps)>] : set audio bitrate, don't use with -f option
[-x <custom resolution width>] : set custom resolution width
[-y <custom resolution height>] : set custom resolution height
[-f <file size limit (MB)>] : set filesize limit (in MB), don't use neither with -v -a options
[-t] : enable audio pass through
[-p <output profile>] : possible values are:
	m - Mobile
	ht - HomeTheater (default)
	hd720 - HD720
	hd1080 - HD1080
	phd - DivXPlusHD
	p4k - DivXPlus4K
	hevc720 - HEVC720
	hevc1080 - HEVC1080
	hevc4k - HEVC4K
	iphone - MP4 AVC for iPhone
	ipad - MP4 AVC for iPad
[-k] : enable trick-play (for DivXPlusHD(phd) profile only and one input media file!)
[-s] : enable video 2 pass encoding
[-d] : enable profile detector
[-b] : enable burn subtitle
[-l] : enable logging and specify (optionally) output directory
[-q] : Set DivXLogger logging level
	DIVX_ALL_MSG          = (1 << 0), // 2 ^ 0 = 1   all message types
	DIVX_CRITICAL_MSG     = (1 << 1), // 2 ^ 1 = 2   Critical error
	DIVX_ERROR_MSG        = (1 << 2), // 2 ^ 2 = 4   Error
	DIVX_WARNING_MSG      = (1 << 3), // 2 ^ 3 = 8   Warning
	DIVX_INFO_MSG         = (1 << 4), // 2 ^ 4 = 16  Information
	DIVX_HEADER_MSG       = (1 << 5), // 2 ^ 5 = 32  Heading, usually marks start of group of related messages
	DIVX_DEBUG_MSG        = (1 << 6), // 2 ^ 6 = 64  Debug message
	DIVX_PROGRESS_MSG     = (1 << 7)  // 2 ^ 7 = 128 Some progress
[-w] : disable WPP(Wavefront Partitioning Processing), works in case of HEVC profiles only
[-u <output profile>] : HEVC quality level, works in case of HEVC profiles only. Possible values are:
	fastest - HEVC Quality level: fastest
	fast - HEVC Quality level: fast
	balanced - HEVC Quality level: balanced
	better - HEVC Quality level: better
	best - HEVC Quality level: best
[-h] : help
It is a lot faster than DivX265, supports Avisynth input (but, sadly doesn't support input via pipe/std::In).
Using
Code:
DivXEngine.exe -i test.avs -v 5000 -x 1920 -y 1080 -p hevc1080 -q 128 -u fastest -o test.265
encoding a 10:53min 1920x1080p clip (Elephants Dream) took 10:34min, so since the frame rate of the clip was 24fps the encoding speed with the fastest profile should also be ~24fps.
Haven't done any further testing since the missing 'pipe-input'-support, is a deal-breaker for me, but since I hadn't read about it here I thought I should mention it.

It's not really new...that's their GUI uses as a frontend.

didn't knew it could be used through a command line interface, never saw that anyone posted about it here in the forum, so for me it was new

this parameters is a really new. 2 pass encoding will produce really better quality than 1 pass bitrate mode.

Well...this has been introduced when they have jumped in the AVC content, in 2009-2010 ?!!

well don't work here. It's a new update? Because my divxconverter up to december and "check update" say no new update available?

Simply downloaded it from the official homepage a day before I posted, installed it inside a VM and copied the 'DivX Transcode Engine' folder to my main system for the testing.

Surprised that nobody has mentioned the updated DivX265 encoder. It has a new fastest setting and also constant quantizer settings.

DivX265 is almost twice as fast at new fastest setting (1) as x265 at ultrafast preset.
