Titling framework using HTML, GSAP, and WebVFX for MLT.
Tested on Linux only (Ubuntu 16.04 LTS).
You need melt and the WebVFX plugin from the MLT project. While melt is generally avaiable in most distros, WebVFX is not. Two options:
Build it all from source.
sudo apt-get install libmlt-dev libmlt++-dev build-essential qt4-dev-tools libavcodec-dev libavdevice-dev libavfilter-dev libavresample-dev libavutil-dev libswscale-dev
Build and install:
Install Shotcut, the MLT based video editor, from a all-inc tarball.
https://www.shotcut.org/download/
Unpack somewhere and update your environment.
e.g.
cd ~/opt/
tar -xjvf shotcut-debian8-x86_64-160901.tar.bz2
export PATH=~/opt/Shotcut/Shotcut.app/:$PATH
export LD_LIBRARY_PATH=~/opt/Shotcut/Shotcut.app/lib/:$PATH
(Quick hack because Wirecast dropped support for Animation Codec temporarily with Version 6)
./render_all_lt_next.sh
Puts renders in ~/Videos/egx/*day/lowerthirds/
./render_all_slates.sh
Puts renders in ~/Videos/egx/*day/slates/
Just edit the render_*.sh scripts, it's all in there - just check for quotes and bash special chars, etc (or rather, don't use 'em) ;-)
The <key>="<val>" pairs are for template variable substitution. See templates and scripts for examples.
Render a template to an Apple Animation Codec MOV file, which has transparency for use in Wirecast. Duration is seconds.
bin/qtrle_render_slide.sh -d <duration> templates/<template>.html <output>.mov [<key>="<val>" ...]
Render an MP4 which can be used when no transparecny required.
bin/render_slide_noalpha.sh -d <duration> templates/<template>.html <output>.mov [<key>="<val>" ...]
