Hi, It looks like the -f concat options has a problem when mixingUNC paths in the concat file and local concat file path in command line: Concat file: ffconcat version 1.0 file '\\server\CanonXF\CONTENTS\CLIPS001\AA4002\AA400201.MXF' file '\\server\CanonXF\CONTENTS\CLIPS001\AA4002\AA400202.MXF' file '\\server\CanonXF\CONTENTS\CLIPS001\AA4002\AA400203.MXF' file '\\server\CanonXF\CONTENTS\CLIPS001\AA4002\AA400204.MXF' file '\\server\CanonXF\CONTENTS\CLIPS001\AA4002\AA400205.MXF' Full command: "D:\FFMpeg\x64\ffmpeg.exe" -f concat -safe 0 -i "d:\temp\AA4002.mxf.concat" -map 0 -c copy -y "d:\temp\AA4002.mxf"
As a quick workaround you can use forward slashes instead of backslashes in the paths you use.

There's nothing else wrong with the command or concat files cause if I change the content of the concat file to the local representation of the \\server\CanonXF share E: it works just fine. Same if the concat file is on the \\server share. So it seems that concat wants the files in the list to have the same path type as the concat file itself.
