現在電腦的組態是這樣的: Intel Pentium Dual Core E5200 Windows Vista SP2 Home Basic nVIDIA GeForce G100 K-Lite Codec Pack 7.00 Full Real Alternative 2.0.2 Lite LAV CUVID decoder 0.13 (Legacy CUDA build) 原本是想要參考01的這篇來做倍頻效果 http://www.mobile01.com/topicdetail.php?f=347&t=1576237 可是因為這樣做就沒辦法開DXVA, 後來看到別的地方說可以以raw video的方式先倍頻再丟給DXVA做處理, 所以又去抓了LAVCUVID來試之後在MPC-HC在外部篩選器指定了ffdshow raw video filter >> LAVCUVID: http://i.imgur.com/tWJXt.png

播放時也的確確認是先讓ffdshow作處理再丟給LAV CUVID: http://i.imgur.com/0NYle.jpg

可是一旦開了avisynth裡的語法之後色彩就會離奇色偏: http://i.imgur.com/yAxhu.jpg

但是從上面的frame rate跟觀感的確能證明avistnth的語法是有作用的 http://i.imgur.com/TeEhS.jpg

<< 關閉avisynth處理, 色彩正常. 請問這樣子是ffdshow, avisynth, 還是LAV CUVID的問題? ※影片訊息補上: Gerneral Format : Matroska File size : 376 MiB Duration : 26mn 3s Overall bit rate : 2 016 Kbps Encoded date : UTC 2009-11-14 19:36:32 Writing application : mkvmerge v2.9.0 ('Moanin'') built on May 22 2009 17:46:31 Writing library : libebml v0.7.7 + libmatroska v0.8.1 Video ID : 1 Format : AVC Format/Info : Advanced Video Codec Format profile : High@L5.0 Format settings, CABAC : Yes Format settings, ReFrames : 8 frames Codec ID : V_MPEG4/ISO/AVC Duration : 26mn 3s Nominal bit rate : 1 500 Kbps Width : 1 280 pixels Height : 720 pixels Display aspect ratio : 16:9 Frame rate : 23.976 fps Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Bits/(Pixel*Frame) : 0.068 Writing library : x264 core 68 r1183M f21daff Encoding settings : cabac=1 / ref=8 / deblock=1:1:1 / analyse=0x3:0x133 / me=esa / subme=8 / psy_rd=0.6:0.0 / mixed_ref=1 / me_range=16 / chroma_me=1 / trellis=2 / 8x8dct=1 / cqm=0 / deadzone=21,11 / chroma_qp_offset=-2 / threads=3 / nr=0 / decimate=1 / mbaff=0 / bframes=16 / b_pyramid=1 / b_adapt=1 / b_bias=0 / direct=3 / wpredb=0 / keyint=250 / keyint_min=25 / scenecut=40 / rc=2pass / bitrate=1500 / ratetol=1.0 / qcomp=0.60 / qpmin=10 / qpmax=51 / qpstep=4 / cplxblur=20.0 / qblur=0.5 / ip_ratio=1.40 / pb_ratio=1.30 / aq=1:1.00 Audio #1 ID : 2 Format : AAC Format/Info : Advanced Audio Codec Format profile : LC Codec ID : A_AAC Duration : 26mn 3s Channel(s) : 2 channels Channel positions : Front: L R Sampling rate : 48.0 KHz Compression mode : Lossy Audio #2 ID : 3 Format : AAC Format/Info : Advanced Audio Codec Format profile : LC Codec ID : A_AAC Duration : 26mn 3s Channel(s) : 2 channels Channel positions : Front: L R Sampling rate : 48.0 KHz Compression mode : Lossy -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 125.232.138.158
