Bash Script: Video Contact Sheet Generator & ImgChili Uploader | 3:4 Aspect Ratio

Peter South · Oct 1, 2013

This is a Bash script I wrote some months back that does the following:

Uses the Dhyana.pl PERL script to generate contact sheets of videos.
Uploads the contact sheets using cURL to an imgChili account.
Retrieves the URLs for each contact sheet.
Formats the links into [BBCode] which can be then copied and pasted into DDL sites.

Please Note:

This script specifically for use on a directory of videos which have a 3:4 standard aspect ratio.
For my similar script for 3:4 standard aspect ratio videos please see:
Bash Script: Video Contact Sheet Generator & ImgChili Uploader | 16:9 Aspect Ratio
This script also works well with my LuckyShare Bash Uploader Script:
Bash Uploader For LuckyShare v1.30923

Code:

#! /bin/bash
# Script: /usr/local/bin/thumberSD.sh
# Version 13.1001
# Written by SpecialEd @ irc.fileguide.org
# Generates a contact sheet for all videos in a directory that the script is run from.
# This script intended only for videos with a 3:4 standard aspect ratio (SD).
# Once all images are generated they are then uploaded into an authenticated imgChili account,
# retrieves the images' links and formats the URLs into [BBCode] for forums & blogs.
