Archived

Please see Patrick330's fork of this script.

ClassDojo changes their site regularly, so a script like this needs regular maintenance. I have decided to archive this project and stop providing updates. Patrick330's fork linked above may be a good alternative.

Original Purpose

ClassDojo is a classroom communication app used to share reports between parents and teachers. Teachers track student behavior and upload photos or videos. The gamification style system teaches developmental skills through real-time feedback.

git clone myusername@myserver:/home/git/myrepo

// A pattern I often find myself using consists of a report-type page that
// displays any amount of data. At the top of that page is a `<form>` containing
// one or more `<select>` elements whose purpose is to filter the data on the
// report.

// The form uses `method="GET"`, which is great to make sure that the URL stays
// in line with what the page shows. A user can bookmark/favorite the URL and
// come back to it later. A user can share the URL so other users can see
// exactly the same page.

# Takes a video file and trims it to a specified time range, while also
# adjusting quality for a smaller, shareable size.
#
# Example usage:
# .\shrinkvid.ps1 video.mp4 00:00:10 00:00:20
#
# This will invoke ffmpeg with the following command:
# ffmpeg -i "video.mp4" -vf scale=-2:720 -r 60 -crf 28 -ss 00:00:10 -to 00:00:20 "video_small.mp4"
#
# Make sure ffmpeg.exe is in your PATH
