Technical support Introduction ------------ The DivX(R) codec 5.1.1 codec is the latest and greatest release of DivX. With DivX 5.1.1 we've been able to make it more than twice as fast than the really slow one we released last time! ;) Go to the end of the README for more cheesie marketing one liners. Joking aside DivX 5.1.1 does actually offer the best Quality and Performance of any release in DivX History. We finally got it right! The DivX codec (short for COmpression-DECompression) is the standard for high quality video over IP networks because it hits the sweet spot between superior visual quality and small file size. With a broadband connection, you can download a full-length feature film in the time it takes to have a pizza delivered! Installation instructions ------------------------- To install the DivX codec, you should follow the following simple steps: 1. Copy the installer program (DivXProBundle.exe) to a location on your hard drive (e.g., C:\temp). 2. Run the installer program by double-clicking on the DivXProBundle.exe icon. 3. Follow the instructions of the installer program to install the DivX Pro software. 4. Done!

Other Cheesie One Liners we came up trying to describe what's so good about 5.1.1 :) ------------------------------------------------------------------------------------ - We thought we would try making it both look good and fast this time... - More than 2 times faster than the really slow one we released last time - More than 100% faster than the last release* *last release was 60% slower than the one before that, but whatever. - Speed and quality, together at last. Like peanut butter and chocolate or pickles and fudge if you're pregnant. - We made a deal with the aliens, we got both speed and quality technology for our codec, they got the Midwest. Sorry Oklahoma. - Hey we finally got it right! ...speed and quality…together for the first time - tap tap tap... is this thing on? - Introducing the bionic codec ...the speed of 5.05 with the quality of 5.1...faster…smarter…just better. - two guys walk into a bar, third one ducks DivX Pro(tm) Software ===================== Version: 5.0.5 Pro README file updated on: 2003-04-24 (c) Copyright DivXNetworks, Inc.

What's new in this version -------------------------- What’s 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: What’s 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 codec’s 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 doesn’t 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. What’s Changed: * The new RC doesn’t 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!
