I’m getting unexpected results from a process that I’ve previously used successfully to detelecine old DVDs when converting to h264.
Here’s my source excerpt: https://dl.dropboxusercontent.com/u/42718751/2023_telecine_source.zip Here’s the correctly converted excerpt using mencoder with the command line, "mencoder '2023_telecine_source.mpg' -o '2023_telecine_detelecine.m4v' -of lavf -lavfopts format=mp4 -alang en -aspect 4:3 -demuxer lavf -vf filmdint=fast=0/sad_thres=2048,fspp,softskip -mc 0 -noskip -oac faac -faacopts br=320:mpeg=4:object=2:raw -ofps 24000/1001 -ovc x264 -x264encopts crf=28:bitrate=2000:nocabac:level_idc=31:bframes=0:global_header:threads=auto:subq=6:frameref=2:partitions=all:trellis=1:chroma_me:qcomp=0.7:qp_step=4:me=umh:weightp=0:8x8dct=0:direct_pred=auto ‘“: https://dl.dropboxusercontent.com/u/42718751/2023_mencoder_detelecine.zip Here’s the incorrectly converted excerpt using ffmpeg with the command line, "ffmpeg -i '2023_telecine_source.mpg' -pix_fmt yuv420p -c:v libx264 -preset slower -tune film -vf "fieldmatch=order=tff:combmatch=full" -r 24000/1001 -c:a libfdk_aac -b:a 320k -crf 18 -x264opts keyint=40:bitrate=2100:qpmin=8:qpmax=28:qpstep=4 '2023ffmpeg_telecine..m4v’”: https://dl.dropboxusercontent.com/u/42718751/2023_ffmpeg_detelecine.m4v.zip Please tell me how ffmpeg may be used to correctly detelecine the source so that the output compares favorably with the mencoder output.
