Hello I am trying to upscale a 720x608 (incl VBI) 25i 4:3 source to 1920x1080 25i 16:9.
My deinterlacing and reinterlacing is working, scaling and cropping too. But I have understanding problem how to use the videofilter regarding aspect ratios. My source is 4:3 and the target is 16:9. For the target I am expecting that I get a PillarBox FullHD image (black bars left and right) where the original 4:3 aspect ratio of the source is kept. PROBLEM: But I get only a stretched 16:9 HD version of the 4:3 original image. (no black bars at left and right) See files: https://www.dropbox.com/s/mgwmiitcpgta0ym/scalertest.zip?dl=0 CommandLineOutput: ffmpeg -i "F:\scaler test\_5sec.avi" -vf "crop=720:576:0:32, setfield=tff, yadif=1:0:0, scale=-1:1080, tinterlace=interleave_top, fieldorder=tff" -vcodec ffvhuff -an -s 1920x1080 -aspect 16:9 "F:\scaler test\_5sec_fullHDinterlaced.avi" ffmpeg version 3.4 Copyright (c) 2000-2017 the FFmpeg developers built with gcc 7.2.0 (GCC) configuration: --enable-gpl --enable-version3 --enable-sdl2 --enable-bzlib --enable-fontconfig --enable-gnutls --enable-iconv --enable-libass --enable-libbluray --enable-libfreetype --enable-libmp3lame --enable-libopenjpeg --enable-libopus --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libtheora --enable-libtwolame --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxml2 --enable-libzimg --enable-lzma --enable-zlib --enable-gmp --enable-libvidstab --enable-libvorbis --enable-cuda --enable-cuvid --enable-d3d11va --enable-nvenc --enable-dxva2 --enable-avisynth --enable-libmfx libavutil 55. 78.100 / 55. 78.100 libavcodec 57.107.100 / 57.107.100 libavformat 57. 83.100 / 57. 83.100 libavdevice 57. 10.100 / 57. 10.100 libavfilter 6.107.100 / 6.107.100 libswscale 4. 8.100 / 4. 8.100 libswresample 2. 9.100 / 2. 9.100 libpostproc 54. 7.100 / 54. 7.100 Input #0, avi, from 'F:\scaler test\_5sec.avi': Metadata: encoder : Lavf58.12.100 Duration: 00:00:05.00, start: 0.000000, bitrate: 116115 kb/s Stream #0:0: Video: ffvhuff (FFVH / 0x48564646), yuv422p, 720x608, 107684 kb/s, SAR 152:135 DAR 4:3, 25 fps, 25 tbr, 25 tbn, 25 tbc Stream #0:1: Audio: pcm_s24le ([1][0][0][0] / 0x0001), 48000 Hz, 7.1, s32 (24 bit), 9216 kb/s File 'F:\scaler test\_5sec_fullHDinterlaced.avi' already exists.
