The difficult part is, most sources aren't entirely telecined. Other parts can be safely brought down to 24fps. For example, title cards might have been done on a computer at 30fps, while live-action material was shot with a film camera at 24fps and then telecined. Other times, part might be progressive 24fps (soft telecined). If you bring the entire source up to 24 frames per second, the part that is supposed to run at 30fps will be displayed too slowly. If you bring the entire source down to 30 frames per second, the part that is supposed to run at 24fps will appear jerky. The solution is to leave everything at the speed it was meant to play at. 30fps for 30fps stuff, 24fps for 24fps stuff. Leave the soft telecined parts progressive, detelecine the hard telecined parts to be progressive. When this is done within one movie file, it's called variable frame rate. The frames per second vary between 24 and 30. Estimating duration from bitrate, this may be inaccurate If not, does that mean that the output of the encoding GUI is not as smooth in terms of playback compared to HandBrake?Ĭode: ffmpeg.exe -i test-crf18-vfr.mkv -vcodec copy -acodec copy -vbsf h264_changesps=cfr/fps=24000:1001 outfile.mkvįfmpeg version git-N-29946-g27614b1, Copyright (c) 2000-2011 the FFmpeg developers If I encode a similar source with other encoding GUI using QTGMC, will I end up with VFR like HandBrake? A place for everything, and everything in its place. Stream #0.Run the container in the background. If not set, the container runs in the foreground. Pass an environment variable to the container. See the Environment Variables section for more details. Set a volume mapping (allows to share a folder/file between the host and the container). See the Data Volumes section for more details. To customize some properties of the container, the following environment Set a network port mapping (exposes an internal container port to the host). Variables can be passed via the -e parameter (one for each variable). See User/Group IDs to better understand when this should be set. See User/Group IDs to better understand when this should be set.Ĭomma-separated list of supplementary group IDs of the application. Mask that controls how file permissions are set for newly created files. The value of the mask is in octal notation. See the following online umask calculator: By default, this variable is not set and the default umask of 022 is used, meaning that newly created files are readable by everyone, but only writable by the owner. Timezone can also be set by mapping /etc/localtime between the host and the container. When set to 1, the application will be automatically restarted if it crashes or if a user quits it. Priority at which the application should run. A niceness value of -20 is the highest priority and 19 is the lowest priority. By default, niceness is not set, meaning that the default niceness of 0 is used.
