Sort of like this http://home.earthlink.net/~tacosalad/video/dotcrawl.html I think I named my files more generally when I uploaded them. test_720x486i_dotcrawl.mov shows more of the rainbow effect in some of the detail areas than the dot crawl. I tested processing that clip to 23.98 in this command line example. ffmpeg.exe -r 30000/1001 -i D:\media\test_720x486i_dotcrawl.mov -filter_complex [0:0]crop=704:480:8:6,pullup,dejudder,idet,yadif=mode=1:deint=interlaced,atadenoise,scale=640x480,setsar=sar=1/1,setfield=prog[v_0];[0:1][0:2]amerge=inputs=2[amerge_0_0];"[amerge_0_0]pan=2c|c0=c0|c1=c1[pan_0_0]" -map "[v_0]" -map "[pan_0_0]" -r 24000/1001 -c:v libx264 -crf 19 -r 24000/1001 -c:a aac -movflags +faststart -shortest D:\media\test_640x480.mp4 ffmpeg version N-77547-g2893dbf Copyright (c) 2000-2015 the FFmpeg developers built with gcc 5.2.0 (GCC) configuration: --enable-gpl --enable-nonfree --enable-libx264 --enable-libx265 --enable-libfdk_aac --enable-static --disable-shared --enable-libfreetype --enable-libfontconfig libavutil 55. 11.100 / 55. 11.100 libavcodec 57. 20.100 / 57. 20.100 libavformat 57. 21.100 / 57. 21.100 libavdevice 57. 0.100 / 57. 0.100 libavfilter 6. 22.100 / 6. 22.100 libswscale 4. 0.100 / 4. 0.100 libswresample 2. 0.101 / 2. 0.101 libpostproc 54. 0.100 / 54. 0.100 Guessed Channel Layout for Input Stream #0.1 : mono Guessed Channel Layout for Input Stream #0.2 : mono Guessed Channel Layout for Input Stream #0.3 : mono Guessed Channel Layout for Input Stream #0.4 : mono Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'D:\media\test_720x486i_dotcrawl.mov': Metadata: major_brand : qt minor_version : 537199360 compatible_brands: qt creation_time : 2016-01-22 21:27:58 com.apple.quicktime.player.movie.audio.gain: 1.000000 com.apple.quicktime.player.movie.audio.treble: 0.000000 com.apple.quicktime.player.movie.audio.bass: 0.000000 com.apple.quicktime.player.movie.audio.balance: 0.000000 com.apple.quicktime.player.movie.audio.pitchshift: 0.000000 com.apple.quicktime.player.movie.audio.mute: com.apple.quicktime.player.movie.visual.brightness: 0.000000 com.apple.quicktime.player.movie.visual.color: 1.000000 com.apple.quicktime.player.movie.visual.tint: 0.000000 com.apple.quicktime.player.movie.visual.contrast: 1.000000 com.apple.quicktime.player.version: 7.6.6 (7.6.6) com.apple.quicktime.version: 7.7.3 (2943) 0x7738000 (Mac OS X, 10.11.3, 15D21) Duration: 00:00:19.35, start: 0.000000, bitrate: 33131 kb/s Stream #0:0(und): Video: prores (apcs / 0x73637061), yuv422p10le(bt470bg/smpte240m/bt709), 720x486, 28517 kb/s, SAR 10:11 DAR 400:297, 29.97 fps, 29.97 tbr, 30k tbn, 30k tbc (default) Metadata: creation_time : 2016-01-22 21:27:58 handler_name : Apple Alias Data Handler encoder : ProRes 422 (LT) timecode : 00:59:20;00 Stream #0:1(und): Audio: pcm_s24le (in24 / 0x34326E69), 48000 Hz, 1 channels, s32 (24 bit), 1152 kb/s (default) Metadata: creation_time : 2016-01-22 21:27:58 handler_name : Apple Alias Data Handler Stream #0:2(und): Audio: pcm_s24le (in24 / 0x34326E69), 48000 Hz, 1 channels, s32 (24 bit), 1152 kb/s (default) Metadata: creation_time : 2016-01-22 21:27:58 handler_name : Apple Alias Data Handler Stream #0:3(und): Audio: pcm_s24le (in24 / 0x34326E69), 48000 Hz, 1 channels, s32 (24 bit), 1152 kb/s (default) Metadata: creation_time : 2016-01-22 21:27:58 handler_name : Apple Alias Data Handler Stream #0:4(und): Audio: pcm_s24le (in24 / 0x34326E69), 48000 Hz, 1 channels, s32 (24 bit), 1152 kb/s (default) Metadata: creation_time : 2016-01-22 21:27:58 handler_name : Apple Alias Data Handler Stream #0:5(und): Data: none (tmcd / 0x64636D74) (default) Metadata: creation_time : 2016-01-22 21:27:58 handler_name : Apple Alias Data Handler timecode : 00:59:20;00 [Parsed_idet_3 @ 00000051505b2e80] Repeated Fields: Neither: 0 Top: 0 Bottom: 0 [Parsed_idet_3 @ 00000051505b2e80] Single frame detection: TFF: 0 BFF: 0 Progressive: 0 Undetermined: 0 [Parsed_idet_3 @ 00000051505b2e80] Multi frame detection: TFF: 0 BFF: 0 Progressive: 0 Undetermined: 0 [Parsed_amerge_9 @ 00000051505ca3e0] No channel layout for input 1 [Parsed_amerge_9 @ 00000051505ca3e0] Input channel layouts overlap: output layout will be determined by the number of distinct input channels [Parsed_pan_10 @ 00000051505ca0e0] Pure channel mapping detected: 0 1 No pixel format specified, yuv422p for H.264 encoding chosen.
