Make Image Sequence Script

Hi, this is a simple script to rename image sequences. Namely, it does two things:

1. Renumbers the image sequence from 0

2. Looks at the directory’s name in which the sequence is held and prepends that name to the entire sequence.

Some programs do not accept image sequences that do not start from 0, so this script fixes that. Some programs rely on the image sequences files being named itself and not the directory, this script fixes that too.

Using this Script

First download the script. One way is through git:

git clone https://github.com/sludgeFudge/make-seq

I move the script to ~/Videos/ for easy access.

If you wish to rename an image sequence, simply rename the folder containing the image sequence. It’s best practice to not use spaces so use hyphens - or underscores _.

Then go into the directory and run the script. Ensure only the image sequence is within the directory because this script renames everything in the directory it’s run in.

sh ~/Videos/make-seq.sh

Modifying the Script

You may want to change the character that is used to separate the name and sequence number. By default the script uses an underscore _, resulting in files like sequence_0000.tiff.

If you wish to change this, go to line 33 in make-seq.sh and change the underscore _ to whatever you like.

Or you can use the sed command. Here I replace the underscore _ with a hyphen -:

sed -i.bak '33s/_/-/' make-seq.sh
