Description:Download AutoQMatEnc from the official site


AutoQMatEnc is a free MPEG-2 video encoder that accepts Avisynth scripts as input and can also replace CCE SP usage within DVD Rebuilder. A GUI for AutoQMatEnc is also available: AQE GUI

  • Use same ECL Files than CCE SP Trial
  • Read any AVS script by using directly avisynth.dll
  • Built-In advanced QMatOp technology - Activated by adding adjust_q_matrix=1 in ECL or CCEAQM=1 in the REBUILDER.INI file for DVDRB users. For details about QMatOp go to the forums.
  • MultiPass enabled - Above 4 passes is close from useless but can be performed
  • Part of CCE Simple Settings (Animation/CG/Natural) taken into account : Recomended for Anime (Aniamtion) and old movies (Natural)
  • QMatOp phase not reprocessed but detected if encode cancelled once finished.
  • Pass 1 no reprocessed if already done. Compatible with RB-Farm when used with DVDRB. (Thank you
  • Danpos for finding/testing it!!!)
  • MPEG2 Encoder using a part of libavcodec : libavcodec is released under the LPGP.


Supported File Formats:

Input Files: AVS
Output Files: MPG

OS Compatibility:

Win32 Command Line

Version 0.33
  • Release Date: Aug 12, 2006
  • Corrected OPV, it was not working properly when Q=1 (Thank you Danpos for finding it)
  • Improved OPV quality, should be better but slower!!!!
  • Added new parameters for QMatOp tweakings (Requested by Archeo)
    • qmat_min_intra=### , Minimum value for intra values (default 8)
    • qmat_max_intra=###, Maximum value for intra values (default 255)
    • qmat_min_inter=###, Minimum value for inter values (default 16)
    • qmat_max_inter=###, Maximum value for inter values (default 255)
    • dctune_prec=##, Precision percentage (integer value from 1-100)for DCTune (default 5)
  • Tweaked QMatOp (A bit slower but better) : The default speed is a bit lower
  • MPEG2 CBR implemented....
  • FPS displayed (Requested by Fox Ace)
  • Fine tuned QMatOp for Ultra Low Bitrates
  • Totally rewrote the rate control for high bitrates. (3 passes highly recommended for a good sizing)
    • Constraints are respected now : No more spikes above the Max bitrate
    • Sizing as good as good as "normal" bitrates with 3 passes (1 Vaf + 2 VBR)
  • Tuned QMatOp on very hard to encode scenes. (Ex: Pitch Black "crash down" scene)
  • Added a pulldown function (very experimental) :
    • pulldown_detect=#(1: 23.976->29.97, 2:24.000->29.97, 3:25.000->29.97)
    • It's applied once the movie is encoded, so for a PAL->NTSC conversion, select a PAL encode, then pulldown_detect=3
  • AutoBias : If vbr_bias>=0 , automatic else for a manual bias just set it as a negative value.
  • Added a special mode correction when in high bitrates if the movie is oversized, a new faster method is called to correct it.
  • Added some timed log functions. Now everything is timestamped in the log file.
  • OPV Mode : It should simulate a little bit more the CCE behaviour :
    • Range is now 0-300 like CCE
    • The curve is a 1/x^2 kind of function.....a bit like CCE
  • Tweaked the rate control for the embedded Pulldown application
  • Improved quality at high bitrates.(Macroblock at scene changes bug)
  • Worked on the Rate Control without QMatOp, a new function was implemented in order to work as if QMatOp is on.
  • Corrections of minor bugs.
  • Average FPS written to the log
  • "Animation" mode implemented (Depending on some specific conditions some vids are detected as being animation kind and then the behaviour of the rate control is different)
  • Added a feature in the animation mode : Scene Change Threshold is adjusted if too low.
  • AQE is fully compatible in a multi instance mode now : AQE^n (from Darksoul71) for example
  • Added an auto max QMatOp intra/inter value feature, it seems to correct some macro blocking in some cases (I will call it the Appleseed bug! :) Thanks to swiftninja for finding this one! )
