DivX’de uzun bir aradan sonra 5.1’den 5.2 versiyonuna geçti.
– Smooth playback supporting multiple consecutive B-frames
– Quantizer, now using quant scale in video packets
– Bi-directional coding using an adaptive method
– Fully adaptive multiple consecutive B-frames
– MPEG-2/H.263 quantization choice
– Built-in bitrate calculator
– Update checking tool
– Automatic update notification for the DivX encoder
– Fast mode, revamped for better performance, compression and quality
-Feedback mode which is now multithreaded, taking advantage of HyperThreaded or dual CPU for better efficiency
– 3 point GMC support in the DivX decoder
– “Slowest” mode removed as the quality differential with “Slow” mode was insignificant, yet the performance differential was massive
– DivX Pro Adware bundle replaced by DivX Pro 6-month free trial
A rare issue where rate control sometimes inserted Q=31 frames in video combining low light conditions, high bitrate and specific motion patterns
– Fastest mode to respect the user-specified average bitrate (Old “Fastest” behavior can be obtained by disabling profiles and performing 1-Pass, Quality-based encoding with Q=3)
– A crash occurring in some rare cases with clips that have dimensions divisible only by 2 and use YUY2 color mode
– Black screen when decoding old buggy MPEG-4 clips that lack VOL header
– Internal flush operation with “Smooth playback” feature
– Intra inverse quantization (type 1)
– Support for generic MPEG-4 (XVID and 3ivX)
– Data partitioning clip
– Deblocking to no longer cause solid blocks to appear during playback
– DivX decoder to always play DivX video
