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

Any test samples please?

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.hevcOK... 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.hevcAnd then, it crashed, blaming the user... >DivX265_1.1.18 --input d:\BasketballDrive_1920x1080_50.yuv -s 1920x1080 -br 6018 -I 5 -n 500 -aqo 4 -o d:\DivX42.hevc |

DivX reports...
My tests show the x265 results should look like this...

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 Using Code:
DivXEngine.exe -i test.avs -v 5000 -x 1920 -y 1080 -p hevc1080 -q 128 -u fastest -o test.265 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. Cu Selur |

[-s] : enable video 2 pass encoding
this parameters is a really new. 2 pass encoding will produce really better quality than 1 pass bitrate mode.

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. http://labs.divx.com/divx265 |
