hi, i'm using mencoder to encode interlaced videofiles with x264. To deinterlace the video i'm adding the yadif Filter to the mencoder command line:
mencoder -vfm ffmpeg,dshow,vfw -cache 51200 -of avi -ovc x264 -ofps 25 -aspect 4:3 -oac mp3lame -srate 44100 -mc 0 -field-dominance -1 -vf yadif,scale=768:576,harddup -x264encopts "keyint=250:min-keyint=25:scenecut=40:bframes=0:b-bias=0:ref=5:deblock=-2,-2:crf=22:ratetol=1.0:vbv-bufsize=0:vbv-init=0.0:ipratio=1.4:pbratio=1.3:chroma-qp-offset=0:rceq=blurCplx^(1-qComp):qcomp=0.6:cplxblur=20.0:qblur=0.5:subq=4:partitions=all:direct-8x8=-1:direct=auto:me=hex:8x8dct:trellis=1:nodct_decimate:nr=0:sar=1/1:fps=25:threads=auto:nopsnr:nossim" -lameopts "cbr:preset=128:mode=0" -o OUT.avi IN.mpg
My mencoder version:
MEncoder Sherpya-SVN-r27323-4.2.4 (C) 2000-2008 MPlayer Team
CPU: Genuine Intel(R) CPU T2500 @ 2.00GHz (Family: 6, Model: 14, Stepping: 8)
CPUflags: Type: 6 MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1
Compiled with runtime CPU detection.
The resulting files have a small green band at the beginning (see attachement).
The video material is from a "Sony Handycam DCR-SR90 HDD" and a "Panasonic SDR-S100". The resolution is 704x576 and 720x576.
Any ideas where the green band comes from?
