![]() ffmpeg -i opening.mkv -i episode.mkv -i ending.mkv \ ![]() If you want to avoid the re-encode, you could re-encode just the inputs that don’t match so they share the same codec and other parameters, then use the concat demuxer to avoid re-encoding everything. Note that this method performs a re-encode of all inputs. Use this method if your inputs do not have the same parameters (width, height, etc), or are not the same formats/codecs, or if you want to perform any filtering. The commands are executed seriasly? Then, why I must recode every frame, when only 1/4 of them will be kept? How can I do that in order to gain recoding speed?ī) Why I need FIFO eventually.FFmpeg has three concatenation methods: 1. loglevel error: ffmpeg output information only errors will be displayedĪ) I tried to reverse the order of filters eg.vcodec libx264: codec to compress the video file.crf 14: High quality ensured (0 = uncompressed).To some filter process frame quicker than others e.g. To be fully processed before it is given to the next process - due fifo: a ffmpeg filter that it says to wait frame.vflip, hflip: 180 degrees rotation of the video.fps=32, scale=1920:1080: drop to 32 frames, and reducing video resolution.I finally found out how to do it! ffmpeg -f concat -safe 0 -i VIDEOFILES.txt -filter_complex \
