Frab-Based Into- and Outro-Generator
===========================================
This is a scripted pre-, postroll and pause-clip generator. It takes a Frab/frab schedule-xml and artwork as svg and generates .dv-clips ready-to-use with the [VOC](https://c3voc.de/)-CRS (Conference Recording System) or any other System. It can aĺso be modified to generate Lossless h264 or something different if reqired.

Following the requirements of the CRS-Setup it generates one postroll, one pause-sequence and multiple prerolls - one per Talk in your Schedule-xml, but it should be simple to modify this if your Setup needs it.

- Install python3, python3-lxml, python3-cssutils, inkscape and libav-tools
- Fork this repo on github and clone your personal fork to your local system.
- Copy one of the existing setups (I'd suggest Datengarten `dg` for a start).
- Open `artwork/intro.svg` (preroll template) in inkscape and modify it. You can also just create a new one. For the VOC-Setup you should use a Pixel-Resolution of `1024x576` (16:9 Aspect Ratio).

- Group things together that should be animated together (like subtitle and speaker-text)
- Use Flow-Text (in Inkscape drag an Area of Text instead of just placing a single line). This way the text will automatically wrap inside the specified area if it gets too long.
- Type Placeholder-Texts where the script should substitute content from your schedule.xml. By default the following placeholders are substituted

- modify outroFrames and pauseFrames like before an test them using `./make.py yourproject/ --debug`

- You can use any debianesque linux (can be headless) to generate the videos. More cores help more.
- Run `./make-snapshots.sh yourproject/` to generate a png from a specific time-index of your .dv-files. You can run `./make-snapshots.sh yourproject/ 5` to get a png for the frame at the 5th second of all your dvs. Default is 3 seconds.

Generating an Live-Stream-Overlay
---------------------------------
While your working on your Video-Artwork you can create another required asset: the stream overlay. When we'll live-stream your Talks we can't send prerolls ovet the live-stream. To let your viewer now what program they are watching at, we usually overlay a transparent image over the live-stream like most television programs do, too.
Just create another SVG of the size 1024x576 and throw your logo into your prefered corner. To have it looking good we would suggest
Just create another SVG of the size 1920×1080 (or 1024×576 if you're only targeting the legacy SD-Pipeline) and throw your logo into your prefered corner. To have it looking good we would suggest
- to test it on dark as well as bright background and add a glow or a backround-box if neccessary
- avoid thin lines or small text that will not be visible in the final size
- set an opacity of 0.8 to 1.0 (below 0.8 it usually won't be recognizable on a bumpy background)
Save your file as `artwork/overlay.svg`
When you're done, call `./make-overlay.sh yourproject/` which will generate two .pngs in your artwork directory. One of them looks squeezed - don't worry, that is correct.

It works! It doesn't work!
