Video production toolchain

These tools take raw video and adds a (optional) pre-roll, title card, and endcard.

Setup

Yes, it's in Perl. It works. Maybe I'll convert it to Python some day. Probably not.

To use generate_title you might need to:

sudo cpan install Text::Wrap
sudo cpan install Getopt::Long

You will also need to have mlt-melt and ImageMagick installed. On Fedora, that's:

sudo dnf install mlt
sudo dnf install mlt-freeworld # MP4 support, available in rpmfusion repo.
sudo dnf install newt
sudo dnf install ImageMagick

Next, you need to create the following files:

template_title.png
endcard.png
preroll.mp4 (optional)

The various EXAMPLE files will give you a template to work from, and an idea of necessary file formats/sizes/resolution for YouTube.

The process for generating a video is:

For each video:

Trim off any dead air at the beginning (and, optionally, end) of the video:

./trim raw_video.mp4 "00:01:23"

./trim raw_video.mp4 "00:01:23" "17:18:23"

Note: Trim retains a backup copy of your original video, in case you do this part wrong.

Generate the title card using generate_title

./generate_title "Template File" "Event Name" "Title" "Speaker(s)"

Generate the final video using:

./merge_all raw_video.mp4

This will generate raw_video_final.mp4 which will contain all of the various components, in order.

In case you prefer a guided step-by-step flow, run:

./generate.sh

Credit where due:

All of the mlt tricks came from Brian Proffitt.

The generate_title stuff all came from the ImageMagick docs.
