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 Pokémon 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.
