![]() The above splicing operation is valid on the premise that all video files have the same format encoding, if you need to splice different formats of video files can use the following scriptĮxtra_options= '-vcodec libx264-crf 23-preset medium-acodec aac-strict experimental-ac 2-ar 44100-ab 128k ' Printf "file '%s ' \ n"./*.$2 > Temp_list.txtįfmpeg-f concat-i temp_list.txt-c Copy output.$2 $fileTypeįor f in./*.$2 Do echo "file ' $f '" > Temp_list.txt Done #cut/join videos using ffmpeg without quality lossĮcho "usage:$0 C seconds < File> "Įcho "eg.Since no recoding is required, these two commands are almost instantaneous.įor convenience, I wrote a script to simplify the operation. The stitching is a little more complicated and we need to keep the video files that need stitching in the following format in a list list.txt:įfmpeg-f concat-i **list.txt**-C copy Output.mp4 The Start_time/stop_time format can be written in two different formats: In fact, with the help of ffmpeg, we can accomplish such tasks without video recoding:įfmpeg-i input.mp4-ss **start_time**-t **stop_time**-acodec copy-vcodec copy Output.mp4 can achieve the cutting/splicing of video files of various tools, but often need to do video transcoding, which inevitably brought the loss of video quality, not to mention that long heinous conversion time. The use of downloadhelper/downthemall such tools to download is often the split file. Online video sites now tend to split a video file into n segments to reduce traffic consumption. It's a GUI made for split audio/video files, using FFMPEG.Cutting/stitching video files is a common requirement. If you want to trim the clip without re-encoding the video, use LosslesCut. ![]()
