For what stands 90k? For 90,000 milli seconds? >> -movflags +faststart -c copy CYD_copy.vob > Sadly, output option cannot (easily) be checked for correctness. > Using options that cannot have an effect may reduce your > chance to get good help here (consider the increased time it > needs to understand what's going on / what your intentions are). The probably wrong '+' was taken from the example in the Wiki: https://trac.ffmpeg.org/wiki/Encode/H.264#AdditionalInformationTips Maybe this is an error? Because VOB also is coded with MPEG, I thought this flag may have a positive effect. Anyway, without the flag I get the same ffprobe data. *From:* $ ffprobe CYD_copy.vob Input #0, mpeg, from 'CYD_copy.vob': Duration: 01:16:20.74, start: 0.500000, bitrate: 7068 kb/s Stream #0:0[0x80]: Audio: ac3, 48000 Hz, stereo, fltp, 256 kb/s Stream #0:1[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, bt470bg, top first), 704x576 [SAR 12:11 DAR 4:3], 25 fps, 25 tbr, 90k tbn, 50 tbc *I transcoded with:* $ ffmpeg -i CYD_copy.vob -movflags +faststart -vf atadenoise -c:v libx264 -c:a libmp3lame -q:a 4 CYD_atadenoise_H.264.mp4 *and get:* $ ffprobe CYD_atadenoise_H.264.mp4 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'CYD_atadenoise_H.264_mp3-q4.mp4': Metadata: major_brand : isom minor_version : 512 compatible_brands: isomiso2avc1mp41 encoder : Lavf57.83.100 Duration: 01:16:20.42, start: 0.000000, bitrate: 1403 kb/s Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 704x576 [SAR 12:11 DAR 4:3], 1276 kb/s, 25 fps, 25 tbr, 12800 tbn, 50 tbc (default) Metadata: handler_name : VideoHandler Stream #0:1(und): Audio: mp3 (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 119 kb/s (default) Metadata: handler_name : SoundHandler Does 50 tbc mean, that I still have 50 interlaced half-frames per second, or why is the codecs timebase 50? Thanks for your comments -Ulf > Not necessarily related: "-c copy" cannot change anything > about fields ("half-frames"), I didn't expect that, the question was about: -c:v libx264 > libx264 does not support PAFF > encoding. What is PAFF?
