I'm having a issue with build libThusnelda 20081201,video is blocky, you can clearly see video is blocky in some parts of the video. the Bit rate is high so what is the problem is, on x264 this type of Bit rate will make the video very smooth. can anybody tell me how to get that smooth video and what settings can i use, I'm interested in the advanced usage of Thusnelda with two pass encoding. on the documentation page of Thusnelda is very limited and not much information i had to go search on google to find some answers, looking inside the Thusnelda encoder from the cmd gives information but that i believe is limited and needs to be explained properly here is a frame from the encoded video tralier, as you can see it is very blocky, what i'm wondering is why it is like this when bit rate is high ? i have read through this http://people.xiph.org/~greg/video/ytcompare/comparison.html few times but could not understand what command line is being used. please can somebody update the following http://v2v.cc/~j/ffmpeg2theora/examples.html that is in line with new things added into Thusnelda. http://i26.tinypic.com/25jjo5v.png +--------------------------------------------------------------------------------------------------------------------+ two pass encoding i find on google ffmpeg2theora --first-pass -V 810 -A 64 -c 2 -H 22050 shutterisland-tlr1_h480p.mov ffmpeg2theora --second-pass -V 810 -A 64 -c 2 -H 22050 shutterisland-tlr1_h480p.mov +---------------------------------------------------------------------------------------------------------------------+ my Encoded output information +----------------------------------------------------------------------------------------------------------------------+ General ID : 20952 (0x51D8) Complete name : C:\Documents and Settings\Mysoogal\Desktop\bT\shutterisland-tlr1_h480p.ogv Format : OGG File size : 15.3 MiB Duration : 2mn 30s Overall bit rate : 855 Kbps Writing application : ffmpeg2theora-0.24 Video ID : 24563 (0x5FF3) Format : Theora Duration : 2mn 30s Bit rate : 749 Kbps Nominal bit rate : 810 Kbps Width : 848 pixels Height : 352 pixels Display aspect ratio : 2.409 Frame rate : 23.976 fps Bits/(Pixel*Frame) : 0.105 Writing library : Xiph.Org libThusnelda 20081201 (UTC 2008-12-01) Audio ID : 26334 (0x66DE) Format : Vorbis Format settings, Floor : 1 Duration : 2mn 30s Bit rate : 64.0 Kbps Channel(s) : 2 channels Sampling rate : 22.05 KHz Stream size : 1.15 MiB (7%) Writing library : libVorbis 20081127 (UTC 2008-11-27) +----------------------------------------------------------------------------------------------------------------------+ my test video clip 480p +----------------------------------------------------------------------------------------------------------------------+ General Complete name : C:\Documents and Settings\Mysoogal\Desktop\bT\shutterisland-tlr1_h480p.mov Format : MPEG-4 Format profile : QuickTime Codec ID : qt File size : 42.8 MiB Duration : 2mn 30s Overall bit rate : 2 390 Kbps Movie name : Shutter Island Movie name/More : In theaters 2009 Encoded date : UTC 2009-06-08 15:42:49 Tagged date : UTC 2009-06-08 15:42:52 Writing library : Apple QuickTime Original source medium : 001 Copyright : ? 2009 Paramount Pictures.
