renumSeq 1.4.0

Tool to renumber image sequences.

About renumseq

renumseq is a Unix/Linux command-line-utility for renumbering image-sequences which are most typically used in CG post-production.

renumseq allows you to renumber sequences with an offset or give them a new start frame. It also allows you adjust the padding of the frame numbers.

renumseq uses the syntax of the native output of lsseq to specify the sequence to be renumbered. Therefore it is recommended to also install lsseq as it makes using renumseq easier.

For example, use lsseq to list a sequence, then cut and paste its output as the arguments to renumseq with the appropriate arguments for setting the offset.

renumseq was written to be safe in that it won't unintentionally overwrite any existing files during renumbering.

If renumseq finds that by renumbering a sequence it will write over another frame outside the range specified then it will skip renumbering that sequence (printing a warning) and go onto the next sequence in the list. Naturally there is an option to force renumseq to overwrite those files if desired.

renumseq doesn't need to make temporary copies of files during the renumbering (it does a move of the file), so it's fast.

renumseq also has a useful option, called --replaceUnderscore that changes any underscore-separators (separating the filename from the frame-number) with dot-separators, like this:

filename_[n-m].extension -> filename.[n-m].extension

Protip: If all you want to do is switch the separator from an underscore to a dot, then use a zero offset, plus the --replaceUnderscore argument.

Installing renumseq

python3 -m pip install renumSeq

Testing renumseq

After installing try the following:

$ cd ~
$ mkdir tmp
$ cd tmp
$ touch aaa.001.tif aaa.002.tif aaa.003.tif aaa.004.tif aaa.005.tif
$ lsseq -Z
aaa.[001-005].tif
$ renumseq --verbose --offset 10 'aaa.[001-005].tif'
aaa.005.tif -> aaa.015.tif
aaa.004.tif -> aaa.014.tif
aaa.003.tif -> aaa.013.tif
aaa.002.tif -> aaa.012.tif
aaa.001.tif -> aaa.011.tif
$ lsseq -Z
aaa.[011-015].tif

Note that you may get an error from your shell when you try to run the renumseq command above, without the quotes around the sequence, that might look something like this:

% renumseq -o 10 aaa.[001-005].tif
renumseq: No match.

In which case you need to "escape" the square brackets as they are special characters as far as the shell is concerned. Escape them like this:

% renumseq -v -o 10 aaa.\[001-005\].tif
aaa.005.tif -> aaa.015.tif
aaa.004.tif -> aaa.014.tif
aaa.003.tif -> aaa.013.tif
aaa.002.tif -> aaa.012.tif
aaa.001.tif -> aaa.011.tif

Alternatively you can just enclose the argument in quotes ('aaa.[001-005].tif') like we did in the example above.

Type this:

$ renumseq --help
