Your input is yuv422p10, thus use format filter before pullup/fieldmatch to get proper results. Pullup and fieldmatch internally works only with 8 bit depth formats, (fieldmatch additionally supports post processing input that can be used to get back 10 bit output) thus -vf format=yuv422p,pullup .... is one possible processing version. Otherwise, yuv420p is picked and pullup/fieldmatch get yuv420p processing of auto inserted scale filter which is not aware that input is telecined, and messes up the chroma plane when downsampling to worse quality pixel format. > -r 24000/1001 -pix_fmt yuv420p -y > /Volumes/Drive5/videopress_testing/pullup_test1.mov > ffmpeg version 4.4.1 Copyright (c) 2000-2021 the FFmpeg developers > built with Apple clang version 13.0.0 (clang-1300.0.29.3) > configuration: --prefix=/usr/local/Cellar/ffmpeg/4.4.1_3 --enable-shared > --enable-pthreads --enable-version3 --cc=clang --host-cflags= > --host-ldflags= --enable-ffplay --enable-gnutls --enable-gpl --enable-libaom > --enable-libbluray --enable-libdav1d --enable-libmp3lame --enable-libopus > --enable-librav1e --enable-librist --enable-librubberband --enable-libsnappy > --enable-libsrt --enable-libtesseract --enable-libtheora --enable-libvidstab > --enable-libvmaf --enable-libvorbis --enable-libvpx --enable-libwebp > --enable-libx264 --enable-libx265 --enable-libxml2 --enable-libxvid > --enable-lzma --enable-libfontconfig --enable-libfreetype --enable-frei0r > --enable-libass --enable-libopencore-amrnb --enable-libopencore-amrwb > --enable-libopenjpeg --enable-libspeex --enable-libsoxr --enable-libzmq > --enable-libzimg --disable-libjack --disable-indev=jack --enable-avresample > --enable-videotoolbox > libavutil 56. 70.100 / 56. 70.100 > libavcodec 58.134.100 / 58.134.100 > libavformat 58. 76.100 / 58. 76.100 > libavdevice 58. 13.100 / 58. 13.100 > libavfilter 7.110.100 / 7.110.100 > libavresample 4. 0. 0 / 4. 0. 0 > libswscale 5. 9.100 / 5. 9.100 > libswresample 3. 9.100 / 3. 9.100 > libpostproc 55. 9.100 / 55. 9.100 > Input #0, mov,mp4,m4a,3gp,3g2,mj2, from > '/Volumes/Drive5/videopress_testing/pullup_test.mov': > Metadata: > major_brand : qt > minor_version : 537199360 > compatible_brands: qt > creation_time : 2022-03-08T16:50:01.000000Z > Duration: 00:00:13.41, start: 0.000000, bitrate: 2465 kb/s > Stream #0:0(eng): Video: prores (LT) (apcs / 0x73637061), yuv422p10le(tv, > smpte170m/smpte170m/bt709, top coded first (swapped)), 720x480, 1840 kb/s, > SAR 10:11 DAR 15:11, 29.97 fps, 29.97 tbr, 30k tbn, 30k tbc (default) > Metadata: > creation_time : 2022-03-08T16:50:01.000000Z > handler_name : Apple Video Media Handler > vendor_id : appl > encoder : Apple ProRes 422 LT > timecode : 00:00:00;00 > Stream #0:1(eng): Data: none (tmcd / 0x64636D74), 0 kb/s (default) > Metadata: > creation_time : 2022-03-08T16:50:01.000000Z > handler_name : Time Code Media Handler > timecode : 00:00:00;00 > Stream mapping: > Stream #0:0 -> #0:0 (prores (native) -> h264 (libx264)) > Press [q] to stop, [?] for help > [libx264 @ 0x7fba5f822000] using SAR=10/11 > [libx264 @ 0x7fba5f822000] using cpu capabilities: MMX2 SSE2Fast SSSE3 > SSE4.2 > [libx264 @ 0x7fba5f822000] profile High, level 3.0, 4:2:0, 8-bit > [libx264 @ 0x7fba5f822000] 264 -
