請放心，xuite有說過不轉檔的條件。可以參考： http://blog.xuite.net/xuite.net/xuite/30742498 《教學》影音 - MP4 (H.264+AAC) 免轉檔機制全面開放 http://vlog.xuite.net/play/a1ZjQnZULTM0NDI1NjUubXA0 關於這個影片，我用firefox抓下來的結果是： General Complete name : D:\movie\kVcBvT-3442565.mp4 Format : MPEG-4 Format profile : Base Media Codec ID : isom File size : 105 MiB Duration : 3mn 41s Overall bit rate : 3 972 Kbps Encoded date : UTC 2011-03-06 11:14:15 Tagged date : UTC 2011-03-06 11:14:15 Video ID : 1 Format : AVC Format/Info : Advanced Video Codec Format profile : High@L4.0 Format settings, CABAC : Yes Format settings, ReFrames : 4 frames Format settings, GOP : M=4, N=38 Codec ID : avc1 Codec ID/Info : Advanced Video Coding Duration : 3mn 40s Bit rate mode : Variable Bit rate : 3 800 Kbps Maximum bit rate : 12.6 Mbps Width : 1 920 pixels Height : 1 080 pixels Display aspect ratio : 16:9 Frame rate mode : Constant Frame rate : 30.000 fps Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Bits/(Pixel*Frame) : 0.061 Stream size : 99.6 MiB (95%) Writing library : x264 core 112 r1867 22bfd31 Encoding settings : cabac=1 / ref=3 / deblock=1:0:0 / analyse=0x3:0x113 / me=hex / subme=7 / psy=1 / psy_rd=1.00:0.00 / mixed_ref=1 / me_range=16 / chroma_me=1 / trellis=1 / 8x8dct=1 / cqm=0 / deadzone=21,11 / fast_pskip=1 / chroma_qp_offset=-2 / threads=6 / sliced_threads=0 / nr=0 / decimate=1 / interlaced=0 / constrained_intra=0 / bframes=3 / b_pyramid=2 / b_adapt=1 / b_bias=0 / direct=1 / weightb=1 / open_gop=1 / weightp=2 / keyint=250 / keyint_min=25 / scenecut=40 / intra_refresh=0 / rc_lookahead=40 / rc=2pass / mbtree=1 / bitrate=3800 / ratetol=1.0 / qcomp=0.60 / qpmin=0 / qpmax=51 / qpstep=4 / cplxblur=20.0 / qblur=0.5 / ip_ratio=1.40 / aq=1:1.00 Encoded date : UTC 2011-03-06 10:58:22 Tagged date : UTC 2011-03-05 11:38:54 Audio ID : 2 Format : AAC Format/Info : Advanced Audio Codec Format version : Version 4 Format profile : LC Format settings, SBR : No Codec ID : 40 Duration : 3mn 41s Bit rate mode : Variable Bit rate : 192 Kbps Maximum bit rate : 225 Kbps Channel(s) : 2 channels Channel positions : Front: L R Sampling rate : 44.1 KHz Stream size : 5.00 MiB (5%) Encoded date : UTC 2011-03-06 11:14:15 Tagged date : UTC 2011-03-05 11:38:54 xuite如果會再次轉檔的話， mediainfo顯示的資訊不會和我用一樣的編碼器(x264)吧？而且連x264的版本都一樣吧？而且連所下的轉檔參數都一樣吧？所以不用懷疑xuite的好心，它真的沒有再次轉檔 XD -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 112.105.94.207
