The swiss army knife of lossless video/audio editing
When exporting multiple segments as separate files, LosslessCut offers you the ability to specify how the output files will be named in sequence. The following variables are available to customize the filenames:
Variable | Output |
---|---|
${FILENAME} |
The original filename without the extension (e.g. Beach Trip for a file named Beach Trip.mp4 ) |
${EXT} |
The extension of the file (e.g.: .mp4 , .mkv ) |
${SEG_NUM} |
Number of the segment (e.g. 1 , 2 or 3 ) |
${EPOCH_MS} |
Number of milliseconds since epoch (e.g. 1680852771465 ) |
${SEG_LABEL} |
The label of the segment (e.g. Getting_Lunch ) |
${SEG_SUFFIX} |
If a label exists for this segment, the label will be used, prepended by - . Otherwise, the segment number prepended by -seg will be used (e.g. -Getting_Lunch , -seg1 ) |
${CUT_FROM} |
The timestamp for the beginning of the segment in hh.mm.ss.sss format (e.g. 00.00.27.184 ) |
${CUT_TO} |
The timestamp for the ending of the segment in hh.mm.ss.sss format (e.g. 00.00.28.000 ) |
${SEG_TAGS.XX} |
Allows you to retrieve the tags for a given segment by name. If a tag is called foo, it can be accessed with ${SEG_TAGS.foo} |
Your files must always include at least one unique identifer (such as ${SEG_NUM}
or ${CUT_FROM}
), and they should end in ${EXT}
(or else players might not recognise the files). For instance, to achieve a filename sequence of Beach Trip - 1.mp4
, Beach Trip - 2.mp4
, Beach Trip - 3.mp4
, your format should read ${FILENAME} - ${SEG_NUM}${EXT}
LosslessCut also allows importing/exporting your project (segments) in a variety of file formats.
