Hallo, given a example.mkv media file (the one used was converted with ffmpeg from mp4) the -to option behaves like the -t option when cutting a piece out of the media file an example: $ ffmpeg -ss 00:06:40 -i example.mkv -to 00:32:45 -c copy out-to.mkv will produce the same as: $ ffmpeg -ss 00:06:40 -i example.mkv -t 00:32:45 -c copy out-t.mkv while according to the documentation: * -to is a position * -t is a duration so the should be different background info on the file used: $ mediainfo example.mkv General Unique ID : 2822367661883764499235379928065855239 (0x21F9178234EDE6ACAE58F72F00B4F07) Complete name : example.mkv Format : Matroska Format version : Version 4 File size : 125 MiB Duration : 55 min 42 s Overall bit rate mode : Variable Overall bit rate : 315 kb/s Writing application : Lavf58.45.100 Writing library : Lavf58.45.100 ErrorDetectionType : Per level 1 Video ID : 1 Format : AVC Format/Info : Advanced Video Codec Format profile : High@L3.1 Format settings : CABAC / 4 Ref Frames Format settings, CABAC : Yes Format settings, Reference frames : 4 frames Codec ID : V_MPEG4/ISO/AVC Duration : 55 min 42 s Bit rate : 229 kb/s Width : 1 280 pixels Height : 720 pixels Display aspect ratio : 16:9 Frame rate mode : Constant Frame rate : 20.000 FPS Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Bits/(Pixel*Frame) : 0.012 Stream size : 91.1 MiB (73%) Writing library : x264 core 160 r3011 cde9a93 Encoding settings : cabac=1 / ref=3 / deblock=1:0:0 / analyse=0x3:0x113 / me=hex / subme=7 / psy=1 / psy_rd=1.00:0.00 / mixed_ref=1 / me_range=16 / chroma_me=1 / trellis=1 / 8x8dct=1 / cqm=0 / deadzone=21,11 / fast_pskip=1 / chroma_qp_offset=-2 / threads=22 / lookahead_threads=3 / sliced_threads=0 / nr=0 / decimate=1 / interlaced=0 / bluray_compat=0 / constrained_intra=0 / bframes=3 / b_pyramid=2 / b_adapt=1 / b_bias=0 / direct=1 / weightb=1 / open_gop=0 / weightp=2 / keyint=250 / keyint_min=20 / scenecut=40 / intra_refresh=0 / rc_lookahead=40 / rc=crf / mbtree=1 / crf=23.0 / qcomp=0.60 / qpmin=0 / qpmax=69 / qpstep=4 / ip_ratio=1.40 / aq=1:1.00 Default : Yes Forced : No Audio ID : 2 Format : Vorbis Format settings, Floor : 1 Codec ID : A_VORBIS Duration : 55 min 42 s Bit rate mode : Variable Bit rate : 80.0 kb/s Channel(s) : 1 channel Sampling rate : 48.0 kHz Compression mode : Lossy Stream size : 31.9 MiB (25%) Writing application : Lavc58.91.100 Writing library : libVorbis (Reducing Environment) (20200704 (Reducing Environment)) Default : Yes Forced : No hth, Wim -- System Information: Debian Release: 11.1 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 5.10.0-9-amd64 (SMP w/16 CPU threads) Locale: LANG=nl_BE.UTF-8, LC_CTYPE=nl_BE.UTF-8 (charmap=UTF-8), LANGUAGE=nl_BE:nl Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages ffmpeg depends on: ii libavcodec58 7:4.3.3-0+deb11u1 ii libavdevice58 7:4.3.3-0+deb11u1 ii libavfilter7 7:4.3.3-0+deb11u1 ii libavformat58 7:4.3.3-0+deb11u1 ii libavresample4 7:4.3.3-0+deb11u1 ii libavutil56 7:4.3.3-0+deb11u1 ii libc6 2.31-13+deb11u2 ii libpostproc55 7:4.3.3-0+deb11u1 ii libsdl2-2.0-0 2.0.14+dfsg2-3 ii libswresample3 7:4.3.3-0+deb11u1 ii libswscale5 7:4.3.3-0+deb11u1 ffmpeg recommends no packages.
