“send_frame” will deinterlace but will not modify the framerate of the video. “send_field” will result in a 2x framerate. Seemingly nothing will get the same level of results as QTGMC but bwdif as part of FFmpeg is crazy fast but will still yield much better results than Handbreak will. I use this mailing list reply as a starting point for “fixing” DVD videos, using FFmpeg, for NTSC content.
Given, DVDs video can come in many different ways. ffmpeg -i 'title_t00.mkv' -flags +global_header -vf "fieldmatch=order=auto:combmatch=full,nnedi=weights='./nnedi3_weights.bin':nsize=s48圆:nns=n256:qual=slow:deint=interlaced:pscrn=none,format=yuv420p,decimate" -c:v libx264 -crf 0 -preset veryslow -acodec copy 'deinterlaced_title_t00.mkv' I.e., using FFmpeg, using nnedi3 with max settings as a fallback on troublesome frames, using decimation to delete unnecessary repeated frames. If a person uses MakeMKV you can put the interlaced video into an MKV and modify it from there.įor films actually interlaced to NTSC DVDs, inverse telecine can be used to restore them back to 24 fps, with a high-quality deinterlacer for frames that can not be reversed. Much better deinterlacers exist.ĪviSynth+, VapourSynth, and FFmpeg all have better options included. My $0.02, don’t use Handbrake for deinterlacing. I would in a very first step use the free Handbrake tool to deinterlace the video.
