tommy_vercetti for posting the news that DivX has been updated with dual core support. This from the DivX website:
Today, we"re excited to announce that the DivX 6.1 codec is finally here! It sports a ton of new features and enhancements, perhaps the most impressive being a massive improvement in encoding speed. According to our benchmarks, even a modest single CPU will run anywhere from 14 to 80% faster than the 6.0 codec depending on the quality mode selected. At the same time, brand new support for HT, SMP, Dual Core, and Dual Core + HT CPUs allows for gains of up to 300%!
If you"ve been waiting for an excuse.. err.. "reason" to go dual core it"s just arrived! But enough of this small talk, let"s delve into the details...
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: HKLMSoftwareDivXNetworksDivXSMExclusions.
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.
