Hi, Reino, this is off-list. set _JOB_=c:\work\MISS PETTIGREW LIVES FOR A DAY [2007] set _DELAY2CH_=%_JOB_%DELAY2CH.ac3 set _DELAY6CH_=%_JOB_%DELAY6CH.ac3 set _SOURCEa0_=%_JOB_%a0.ac3 set _SOURCEa1_=%_JOB_%a1.ac3 set _DELAYEDa0_=%_JOB_%DELAYEDa0.ac3 set _DELAYEDa1_=%_JOB_%DELAYEDa1.ac3 echo ffconcat version 1.0>"%_JOB_%CONCATa0.txt" echo file '%_DELAY2CH_%'>>"%_JOB_%CONCATa0.txt" echo file '%_SOURCEa0_%'>>"%_JOB_%CONCATa0.txt" start ffmpeg -y -safe 0 -i "%_JOB_%CONCATa0.txt" "%_DELAYEDa0_%" echo ffconcat version 1.0>"%_JOB_%CONCATa1.txt" echo file '%_DELAY6CH_%'>>"%_JOB_%CONCATa1.txt" echo file '%_SOURCEa1_%'>>"%_JOB_%CONCATa1.txt" start ffmpeg -y -safe 0 -i "%_JOB_%CONCATa1.txt" "%_DELAYEDa1_%"

The quotes are only needed at the end, in the FFmpeg command. > But why so many unneccesary variables?... The variable names document what the step does (e.g. _DELAY2CH_) or what the file is (e.g. _SOURCEa0_, _DELAYEDa0_). The goal is to keep the FFmpeg command line from wrapping, in email for example. ffmpeg -y -safe 0 -i "%_JOB_%CONCATa0.txt" "%_DELAYEDa0_%" And the reason I put tokens in all-caps and with leading and trailing underscores is so that they stand out (e.g. %_JOB_%). >... Also the creation of the > ffconcat-file can be done more efficiently... Efficiency often matters, but not in this case. It's readability that matters here. Thanks for your thoughts. I appreciate your passion to help!--Mark. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
