Always show the complete console output with your command.

There are many reasons for this. For example, the input may have been encoded efficiently (this could be determined by the format, encoder implementation, options used, etc). Secondly, lossy encoding introduces artifacts that become part of the video. When re-encoding a lossy input the encoder will attempt to preserve details including these artifacts which can be detrimental for encoding efficiency resulting in a comparatively higher output file size. Assuming you're using libx264 it by default tries to achieve a certain quality, so trying to guess the output file size is not possible until you do it. However, you can use two-passes if you need to target a specific output file size. Use the slowest -preset (default is "medium") you have patience for. See: https://trac.ffmpeg.org/wiki/Encode/H.264 You may also consider using "-c:v libx265" but it is much slower and HEVC may not be supported by your playback device. Alternatively, use softsubs to avoid re-encoding video. Consider outputting to MKV if your player supports it as MP4 is a poor choice for softsubs. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
