Instagram video automator

This is a 2-stop process with 2 scripts.

Pre-requisites.

1. Make sure that the input file does NOT have spaces in it. You can use the command: for i in *;do mv "$i" "${i// /_}";done on the command-line to replace all spaces to underscores in all files in the current dircetory.
2. FFMpeg must be installed. brew install ffmpeg

Step 1 - Listener

The listener is used to populate a CSV file located in $CSVFILE (see config) which can then be intercepted and updated depending on needs of the file. Namely:

• start time
• duration
• file renaming
• LUT to use.

The listener has two modes. The first is Active listening, which will sit there running until something is placed into the input folder, which will then create the CSV file.

The second is not a listener at all. You just give the ./listener.sh script a single argument of anything, like ./listener.sh once and it'll execute the listener command once only. This is good for placing files into the input folder once and THEN running it.

Step 2 - Converter

The converter will pick up the CSV file and pipe it into the convert_with_ffmpeg script to process.

Config

The config file will allow you to customise the folder locations, filenames and default CSV rows. Also allows you to set whether the intermediate files are deleted and the output files are overwritten.

## list.csv

This list.csv file that is created at the intermediate step is used for any renaming / cutting purposes. The columns are as follows:

filename	start seek point	duration of video	output filename	LUT
filename1.mp4	0	60	newfile	nolut
myvideo2.mov	0	60	original	Alien
KVF645382D.m4v	10	30	original	Drive

Output filename

Use the word 'original' as the output filename to keep the original filename.

LUT

The LUT to be used is a .3DL format. The ones provided are from Triune

Output

The output format is .mov so that iPhone compatibility is at maximum.
