If your clips don't use the same codecs for audio and video and/or have different rates, your stuck re-encoding to intermediate files prior to joining which as we all know is both time and resource consuming. The concat demuxer is a far better choice for most projects.Īn alternative suggestion: Personally I prefer using the Matroska container due to it's flexibility and low overhead and join videos with the same encoding using mkvmerge -o output.mkv input1.mkv + input2.mkvĬoncatenation of files with different codecs: The above is only included in an attempt to create a thorough answer. Note: as mentioned above the concat protocol is severely limited in what streams and containers it supports so I never use it.

preferred distributions of linux because it is widely used, secure and updates regularly. Note: All the clips must already exist or the command will fail because decoding won't start until the whole list is read.įfmpeg -i "concat:video1.ts|video2.ts|video3.ts" -c copy output.ts LosslessCut is a lightweight, cross platform video editor. There are tips for auto generating the file available in the docs. It's possible that this may vary with your version of ffmpeg. the "copy codec" is blazing fast.Įdit: Note that although the docs say you don't need -safe 0 if the paths are relative, my testing indicates it's a requirement. The files will be stream copied in the order they appear in the vidlist.txt into the output container. LosslessCuts player is based on Chromium, so most browser-friendly formats are accepted (MP4, MOV, WebM, MKV, OGG, WAV, MP3, AAC, H264, Theora, VP8, VP9). In case it's not abundantly clear, replace output with the video filename you wish to produce (whether that be output.mp4, output.mkv, output.avi) ffmpeg will utilize the container indicated by the extension. Note that these can be either relative or absolute paths.įfmpeg -f concat -safe 0 -i vidlist.txt -c copy output VirtualDub seems to have problems with 24-bit audio, converting it to 16-bit when saving the file. Specifically, I need to insert a 44100 Hz 24-bit WAV (PCM) file into a video.

The demuxer is more flexible – it requires the same codecs, but different container formats can be used and it can be used with any container formats, while the concat protocol only works with a select few containers.Ĭreate a text file named vidlist.txt in the following format: file '/path/to/clip1' file '/path/to/clip2' file '/path/to/clip3' Im looking for a free software that will allow me to replace the audio track of a video and leave the audio uncompressed / lossless. This file is in 4.2.2 format, but there are many other files in 4.2.0 format that are muxed and remuxed with the "VideoRedo" program without this problem.There are two methods within ffmpeg that can be used to concatenate files of the same type: the concat demuxer & the concat protocol It lets you quickly extract the good parts from your videos and discard many gigabytes of data without doing a slow re-encode and thereby losing quality. As a rule, these are files downloaded from satellites in a container *.tsĪs an example, if this file is remuxed using the "LosslessCut" program, the defect does not occurs.
