Die Fima DivX Incorporated hat den Videocodec DivX auf Version 6.1 aktualisiert. Wessen System Multi-Core, SMP und/oder Hyperthreading unterstützt, soll von dramatischen Geschwindigkeitssteigerungen profitieren. Aber auch Besitzer herkömmlicher System mit nur einer CPU dürfen sich über deutliche Geschwindigkeitszuwächse freuen. Auch das Feedback-Fenster wurde überarbeitet und bietet nun neue Optionen an.
Momentan ist nur die Windows-Version des Pro-Codecs verfügbar, wie immer als kostenlose, sechsmonatige Trialversion. Wer anlässlich des fünften Geburtstages von DivX eine kostenlose Lizenz ergattern konnte ist fein raus, denn auch mit diesen Lizenzschlüsseln ist ein Update möglich. Allerdings sollte man bei der Installation etwas Vorsicht walten lassen. Die Standardinstallation möchte Google Desktop installieren, so man es nicht explizit abwählt.
New:
Full support for single CPU, HyperThreaded (HT), dual CPU (SMP) and dual core processors. Encoding performance is improved up to 180% for HT CPUs and up to 250% for Dual Core + HT.
Mutlithreading is enabled in the DivX decoder for DirectShow when the option to 'Reduce CPU spikes using one frame delay' is enabled and post-processing is applied.
Optimizations have been added for processors supporting SSE2 extensions.
A new "High Performance" encoding mode has been added.
A new "1-Pass Target Quantizer" mode has been added.
The codec now includes a Lanczos resize filter for very sharp resizing.
The Feedback Window now displays VBV level and has variable axis for PSNR plots.
The Feedback Window now contains controls for changing VBV bitrate, performance mode and psychovisual enhancement in real time during encoding.
DivX High Definition profile now permits average bitrates of up to 6 Mbps.
MPEG quantization has been improved.
Brightness, contrast, and saturation controls are now respected by the DivX decoder for DirectShow.
The DivX decoder for DirectShow now respects the option to "Output YUV 4:2:0 when supported."
It is now possible to exclude the Settings Manager by using RegEdit to add the process name to the list under: HKLM\Software\DivXNetworks\DivX\SMExclusions.
Changed:
The performance of "Extreme Quality" and "Insane Quality" modes has been improved.
"Fastest" mode now achieves better compression and produces video compliant with certified encoding profiles.
Quarter-pixel motion estimation has been enhanced for performance and is now available in all modes from "Balanced" through "Insane quality" when "Unconstrained profile" is selected.
Item descriptions in the encoder GUI have been improved for all languages.
Generic MPEG-4 playback support has been improved.
