Complete Version history / Release notes / Changelog for Gordian Knot

0.35.0 pack2
Updated avisynth filters, DGMPGDec, BeSweet and VDubMod

- added possibility of selecting text subs (any extensions apart from *.IDX that is considered VobSub)
- decomb.dll is no longer loaded into almost every script
- Field operation selection is fixed on advanced SaveAVS window
- DGMPGDec updated to version 1.2.1
- some avisynth filters updated

- fixed comp test for x264 on advanced SaveAVS window

- bitrate propagation for x264 fixed again

- now only support rev 107 and up of x264
- fixed bitrate propagation for x264

- comp test changed to use common strategy as was used for b-frames.
- min&max key frame distance is swapped in rev 103, so GK was changed to compensate for that

- quant 18 single pass encoding is used
- snip size of 20 frames is used (as well as min-key interval=20)
- without b-frames algorithm's using all frames for comp test (works within 5% in all my tests so far)

- you should still aim at about 70% quality

- updated translations
- XviD files can be opened directly in GK again
- DVDDecrypter is updated to version

GK 0.27:

- support for avi input. you can open avi files like you used to open d2v-files. i don't
know why, but sometimes certain avi-files won't open - sorry, no fix atm, consider this
feature experimental for now :b

- finally 100% correct pixel-AR values. for detailed information have a look at
Press "Select" in "Input Pixel Aspect Ratio" to have all the choices.
(for Chibi Yasmin)

- you can now edit a script manually before you do a comp-check.

- manono and hakko504 convinced me to replace
VerticalReduceBy2 with SeparateFields().SelectEven()...

- in options you can enter a name for an alternative mpeg2dec.dll that will be used in
the script. you have to put it in you gknot folder. note that you must NOT remove the
original one.

- updated commandline for BeSweet, now using -ota( -hybridgain ).

- some cosmetics.

GK 0.26 beta:

- divx5 pro codec configuration: psychovisual enhancements are available now.

- jonny, author of "Divx5 Enc" (, pointed out that
gknot's compcheck method needs a little adjustment to be accurate with b-frames
enabled. new standard snip size is 14, 2 frames are discarded in each snip.
thank you very much!

- support for trbarrys Simple Resize Filter added. thanx to tom barry for this fast
high quality filter. (btw.: tom is the author of GreedyHMA as well.)

- change: deinterlacing is put before crop now. that's a little slower but less problematic

- Bugfix: compcheck runs audio encoder.

- Bugfix: "IVTC in avs -> correct frame count" should work now.
(this time doom9 did not let me forget!)

- the 0.26 update is an installer pack again.

- some cosmetics.

GK 0.25 beta:

- support for BeSweet added.

this is the default commandline used,
you can fill in azid and lame options:
'-core( -input "'+ac3FileName+'" -output "'+mp3FileName+
'" -logfile "'+LogFileName+'" ) -ota( -G max ) -azid('+
AzidCmdl+') -lame('+LameCmdl+' --scale 1 ) -profile( Gordian Knot 0.26 )'

please note that "--scale 1" is added to your LameCmdl automatically!
you have to put BeSweet into your gknot folder to be able to
check the besweet option (is included in this archive).
Thanx to DSPguru for his support and his great program!
visit his site at

- Cmdline used for azid and lame is stored in a drop-down-list.

- codec configuration changed, gknot now works with DivX5.02

- encoder window offers pro options for divx5.

- default settings for divx5 can be set in "options" and are stored in the registry.

- logfile reader updated for version 4 ("load" and CompCheck).

- divx5 comp-check works fine now. uses your default divx5 settings.

- default avs script changed, now using decomb.dll for ivtc and deinterlacing. Thanx to Donald Graft for providing his great filters!

- Bugfix: Stats reader crashed on SavingPrivatRyan.stats (the most uncompressable movie there is).

- Bugfix: Subs in credits.

GK 0.23 beta:

- a guy called GinkoGreen seems to have fixed the ecf-bug in nandub. - thank you.
i included his version in this update pack.

- bugfix: divx4 2nd pass should work again.

- bugfix: bitrate recalc active in "just mux"- audio mode.

- for the poor guys who need it: anti-shit for divx3.

GK 0.22 beta:

- divx4 compressibility check added.
values seem to be generally 10% higher than with divx3. so i would say lower bits/(pixel*frame) percentage values have to be choosen for divx4 also.
50-60% should be fine, of course this is not tested yet.

- possibility to start a second pass only.

- autocrop function. this is not perfect yet.

- bugfix: comp-check not deleted in queue.

- bugfix: audio 2 bitrate not changeable.

GK 0.21 beta:

no new features, this is a bugfix-release only.

- bugfix: video window "stay on top".

- bugfix: ecf not used. i also added a checkbox. so you can decide if you want to use it or not.

- bugfix: no divx4-muxing when source is wav.

- bugfix: subtitles in credits.

- bugfix: wrong time in logs.

- bugfix: subresync not found.

- bugfix: stop when can't calculate new stats-file.

- bugfix: encoding queue cleared to fast.

- bugfix: ugly colors in win xp.

- more log-info added.

- process priority for encoder-apps is idle now. but i didn't find a way, yet, to prevent vdub/nandub from taking focus.

and maybe others... ;-)

GK 0.20.1 beta:

- fixed the stupid "no aviKnot.dll" - bug.

GK 0.20 beta:

thanx to aquaplaning, who wrote lots of code for this version and is already preparing avi-support for 0.21. (edit: for 0.22 ;-))
thanx to everybody who did help with testing, especially doom9.
encoding features seem to work fine now.

- audio support added. now this really makes it easy! has the official guide.
here a short desription of what you have to do:

audio is processed using azid (2-pass) and lame.

GK 0.19 beta:

the new encoding features have not been tested a lot.
that's why i have to call them EXPERIMENTAL at the moment:

- first and most important: you can start 2-pass-encodings with nandub/vdub in divx3/divx4
(with end-credits-treatment) from within gordian knot with a single click.
the easiest way to do it:

- with the 'now'-button in the 'save avs'-form you can do a compressibility-check with one
try it!

- steady says 'neutral bicubic' is best and now it's there ;-).

- changed divx3-motion correction a little (less reduction in low-luma sequences).
- small curve-treatment bugfix.

- 'add'-buttons (audio-fields) to add file(-sizes) into the calculator.

- (all) encoder-files and settings are stored in the registry for each save-slot,
so you can easily recall you settings and change it for a reencode.

- export and import buttons to save settings in a file. first time you use this a subfolder called
'settings' will be created in you gknot folder. there you can save your *.gks (gordian knot settings).

- icons.

GK 0.18.1 beta:

- fixed the 3-5 Mb oversize 'bug'. (Added a little checkbox in 'interleaving').
finally filesize should be OK - SORRY for this!

- 'preview' button added to check avs-scripts with media-player.

- added a GordianKnot_noECF.vcf that has to be loaded instead of the
default one if no ecf-file is used for encoding.

GK 0.18 beta:

- GUI for avisynth frameserver setup. well, it's pretty straight forward so i can't say much about it.

- Compressibility Check:

- start buttons for smartripper, vstrip and dvd2avi.

- vobsub support (start buttons and avisynth-GUI).

- requested: you can now enter values >=2 for minimum keyframe distance.

- changed the curve-correction GUI a little bit, because there where problems closing the windows. - fixed.

- bugfix: crash when moving the video-trackbar with arrow-buttons. -fixed (i hope).

- 'set credits start'-button added, for trim or credits.ecf.

- close button in video window added.

GK 0.17 beta:

- calculator now supports divx4 ( 1 kBit/s= 1000 Bits).

- 'File List Writer' added: use it to create .lst files (e.g. for graphedit) or .asx files (media play lists, to play multiple avi-files as one).

- bugfix: 'soft bicubic' and 'sharp bicubic' (save avs dialog) was interchanged in last version - fixed.

GK 0.16.1 beta:

-new dialog for avisynth-script creating:
added a draft-script that containes many important avisynth functions and can be edited in gknot directly. thanx to dividee for providing the script.
VCD and SVCD resizing is supported also. open d2v, choose 'input resolution' and 'input pixel aspect ratio' as usual, (pixel)-crop the image if you want. when saving the .avs choose VCD or SVCD. in that case choosen output resolution (and ITU setting) is irrelevant.

-in the d2v-window press play to watch the movie before the first pass.

-in the file-menu of the d2v-window you can now create an ecf-file for end-credits encoding in the first pass. move the slider to the start-frame of end-credits, then press 'create .ecf'. choose the drf-level and keyframe-distance you want, then press save.
use this ecf when doing the first pass with nandub AND UNCHECK no-avi-output.
when calculating the 2nd-pass-stats-file with gknot, enter the same start-frame AND 100% WEIGHT for end-credits.
after loading the GordianKnot_default.vcf in nandub and entering the bitrate, select frame 0 to (creditsstart-1) to not encode endcredits again. later append credits from the firstpass.avi
very small end-credits possible.
more precise size-predictibility.
faster, because you have to encode credits only once.
no scene change detection for credits (but you probably don't need too many keyframes in there anyway...)

-bugfix: when opening an ntsc-d2v (in rare cases) duration (fps) was calulated slightly wrong - fixed.

GK 0.16 beta:

manual curve correction:
after calculating you can raise or lower the bitrate of any selected part, keeping average
bitrate constant. e.g. use it on the
studio trailer,...
enter the 'weight' you want to give the selection (e.g. 120% for raising, 80% for lowering).
enter Smooth Left & Right (a value between 0 and 100%, watch the percentage graph to see
what it does).
press 'push'.

splitting and merging stats-files (suggested by mythrandir):
e.g. for encoding the first pass with more than one cpu or to fit more than one anime-episode on one can calculate parts separately, then merge 'em, or the other way 'round.
press 'copy curve' to later split the curve without changing (calculating) it.
press 'append' to append a stats-file to the one(s) already loaded.
press 'Sel.Section' (in the selection field) to select the parts you loaded one after the other.
press 'save selected' to save the selected part only. the bitrate in the filename will fit the selection.

'little' different curve the 'custom'-buttons in the correction-fields to check out the changes (for EXPERTS only!)

minimum bitrate in nandub now ALWAYS has to be set to 270, no matter what minimum bitrate you are using in gknot to scale the curve!!!

checking 'deinterlace' before saving the .avs adds VerticalReduceBy2 (more to come in next version)

other small changes and many, many bugfixes.
