- | 4. New in this version
- +=========================-
-
- DivX 5.2.1 now includes:
-
- - Support for three new languages
-
- DivX 5.2.1 is available in English, French, German, and Japanese.
-
-
- - Encoder: Bitrate Calculator
-
- You can now calculate the bitrate you need to hit a target file size
- directly within the encoder configuration dialogue. Simply enter your
- target file size, the length of your video, and the audio bitrate.
-
-
- - Encoder: Adaptive Bi-directional Coding
-
- Bi-directionally encoded frames were first introduced in DivX 5.0, giving
- a staggering 20% reduction in file size at equivalent perceptual quality.
-
- To date, all versions of DivX 5 have used only one bi-directionally coded
- frame in sequence. DivX 5.2.1 expands the scope of this feature.
-
- The DivX 5.2.1 encoder selects both single and multiple consecutive
- bi-directionally coded frames adaptively, leading to higher compression
- ratios and even better quality.
-
-
- - Encoder: MPEG2 Quantization
-
- DivX 5.2.1 has better scalability thanks to MPEG2 Quantization support.
- Quantization plays an important role in the process of reducing the data
- used to store the picture. DivX normally uses H.263 quantization, which
- is optimal for low to high bitrate encoding. MPEG-2 quantization is
- useful at extremely high bitrates.
-
-
- - Encoder: Intel SSE3 (Prescott) Optimizations
-
- The DivX 5.2.1 encoder features optimizations for Intel Prescott CPU's,
- improving performance by up to 15%.
-
-
- - Encoder: Multi-threaded Feedback Window
-
- The encoder feedback window is now multi-threaded. If your PC has a
- HyperThreaded CPU, or multiple CPU's, you can now enjoy the benefits of
- real-time encoder feedback and control with minimal impact on encoding
- performance.
-
-
- - Decoder: Generic MPEG-4
-
- The DivX 5.1 encoder included a Generic MPEG-4 decoding option. In this
- release we have improved our generic MPEG-4 support so that your favorite
- decoder can play more of your favorite movies.
-
-
- - Decoder: Blocking fix (Oops!)
-
- The 5.2.1 decoder corrects a small issue that can cause blocks to be
- displayed along high-contrast edges in the picture, mainly affecting anime
- content. Watch PokΘmon as it was meant to be viewed once again!
-
-
- - Automatic update
-
- DivX 5.2.1 can check for updates automatically when you are connected to the
- Internet, prompt you when new updates are available, and download them for
- you.
-
-
- - Handheld Profile update
-
- The handheld profile has been updated to better reflect the capabilities
- of DivX Certified devices already present in the consumer marketplace.
-
- By encoding with the new Handheld profile you can create higher quality
- video for your Handheld Certified device.
-
-
-
- | 5. Optional additional software
