...http://web.mit.edu/xiphmont/Public/theora/demo.html I found this line- Timothy Terriberry estimates a simple self-training range-coding backend could be reasonably expected to decrease bit usage overhead by 15-20%. Is it really true? I found one implementation.... http://svn.xiph.org/trunk/ghost/libentcode/ Did anyone verified this gain? How much is the exact gain? Regards, hrishi

Hi demo pages http://web.mit.edu/xiphmont/Public/theora/demo.html http://web.mit.edu/xiphmont/Public/theora/demo2.html discussed opportunity to add range coding there is already some xiph code: http://svn.xiph.org/trunk/ghost/libentcode/ and Timothy B. Terriberry wrote some time ago === I'd estimate that you'd save ~12% by switching from Huffman to something arithmetic coding-based for video (based on the experiments with H.264... Theora has more flexible Huffman coding for some pieces, and less flexible coding for oth...

Dear all I'm currently using a simple encoding implementation based on the encoding example delivered with theora. Now i tried to change the quality of the output file. Its my understanding, that either a bitrate can be set for Constant Bitrate (CBR) encoding, or a quality (0-63) for Variable Bitrate (VBR). As you might know, the basic Encoder Example uses the so-called 2-Pass method for
