Introduction
------------

  The DivX Pro(tm) 5.0.5 software is the version of DivX(tm) video technology
  designed specifically for professional users. It includes all the features
  of DivX 5.0.5, plus extra advanced encoding technology and integrated encoding
  tools that appeal specifically to the most advanced users.  DivX Pro is more
  than just a codec; it is an integrated suite of video tools.

  The DivX Pro 5.0.5 release now includes the first version of the EKG. The EKG 
  enables an advanced video compressionist to reallocate data to specific scenes 
  within a video clip. The EKG is just one of the new apps and features weve created 
  due to     community demand. The full list of changes and fixes can be found in 
  the Whats New  section.


Installation instructions
-------------------------

  To install the DivX codec, you should follow the following simple steps:

  1. Copy the installer program (DivXPro505Bundle.exe) to a location on 
     your hard drive (e.g., C:\temp).  
  2. Run the installer program by double-clicking on the
     DivXPro505Bundle.exe icon.  
  3. Follow the instructions of the installer program to install the

What's new in this version
--------------------------

Whats Fixed: 

*      Encoding I-Frame only with certain applications(AVIUtil, DVD2AVI, 
       and some video capture applications).



What's new in version 5.0.4
---------------------------
DivX Codec 5.0.4:

Whats Fixed:

*	K6-2 CPU related crash resolved.
*	Not able to change Bitrate Modulation through CLI field.
*	Cosmetic bug when cropping more than 1000 pixels.
*	Cosmetic bug when resize settings are invalid.
*	During 1pass quality-based, Quantizer can now be set to 1 with CLI
*	Multiple error windows no longer open upon entering wrong bitrate modulation option.
*	'Max Keyframe Interval' no longer accepts negative values
*	Multiple error windows no longer open upon entering wrong CLI option.
*	In the Quick Config CLI field, 'Enable Resize' was taking invalid options
*	Remove -b in the Quick Config CLI field, 'Use Bidirectional Encoding' option was not 			
	getting deselected.
*	Fixed CLI inconsistencies when Restore codecs default is pressed.
*	Max bitrate and encoding bit rate(average) was displayed same.
*	Fixed hitting tab in the CLI field to enable 'Use Bidirectional Encoding'
*	Fixed 'Pre Processing Source' Cosmetic bug
*	Fixed: remove -w in the Quick Config CLI field, 'Update Log file' option is not getting 		
	deselected.
*	Fixed: When 'Psychovisual Enhancements' value is set to 4, in the Quick Config CLI field, 		
	mismatch in slider and label options.
*	Various cosmetic fixes in the Encoder GUI
*	Do not prompt Error unchecked as default fixed.
*	Light Psychovisual enabled itself automatically when exiting the CLI field.
*	Max bitrate reset itself to x10 the average when going in the profile tab
*	MPEG4 type Indicator correctly set according to selected encoding parameters
*	No more green first frame at very high bitrates.
*	Crashes with K6-2 should be fixed now
*	Decoder updates the display to the appropriate frame when seeking
*	Decoder remembers the postprocessing settings
*	Fixed some memory leaks related to Psychovisual and nth Pass mode
*	Nth pass RC is tweaked to minimize the usage of high quantizer
*	Nth pass doesnt create an empty frames at the beginning of the clip
*	Brightness/Saturation sliders now working correctly.
*       Certain dark sequences would produce a long period of frames using a Quantizer of 31.
*       Psychovisual Enhancement field sometimes displayed "Custom" instead of Light when                   
	unselected
*       "Do not prompt with errors and warnings" would select itself when random characters were            
	entered in the CLI    after the "-key" option 
*       when "-d 3" option was entered in the CLI field, "Source interlace" became blank.
*       Max bitrate would not update at times. 
*       DirectShow decoder postprocessing slider became disabled with ATI radeon 9700 Graphics card 
*       DirectShow decoder would "fast forward" when seeking backwards.  This could cause synch             
	issues when re-encoding DivX Files using the DivX Decoder Filter.

Whats Changed:

*	The new RC doesnt use Q=1 frames anymore
*	No stuffing used, bitrate can be too low in some extreme cases.
*	Strategy planning for rate control is much faster now
*	Better tracking of the planned RC strategy creating more consistent quality.  

What's New:

*       EKG!
