SeminarAssembler™ — это инструмент для эффективного монтажа семинаров, докладов и прочего образовательного видео, когда важно сшивать несколько разных источников — несколько камер, скринкасты, слайды, и делать это очень быстро и много. (примеры видео см. в http://lib.custis.ru/it-talks).

Образовательное видео?
Что такое правильное обучающее IT-видео, как его смотреть, и немного — как готовить, см мой доклад на Software People-2012:
Этимология: Assembler .-.
- «Сборка»
- Множества гетерогенных медиапотоков:
- Камер
- Скринкастов
- Слайдов
- Переговоров (скайп, IM…).
- Screen2Log-cкринкастов из блоков
- Множества гетерогенных медиапотоков:
- Ассемблер
- «Двухтермовый, строчный» DSL для программирования сцен:

Оно надо? .-.
Перегруженность, Мелкая мышиная моторика, Неавтоматизируемость, Ремесло, Немасштабируемость…
Кому? .-.
- Программистам
- Тестировщикам
- Advanced Users
Требующим эффективность!
Понимающим, что такое:
- Файл
- Код
- Проект
- Сборка
Основная идея .-.
Матрешка .-.
Принципы .-.
- Agile-видеомонтаж
- Быстрая draft-версия (матрешка!)
- Инкрементальные улучшения
- WYSIWYM — What You See Is What You Mean
- Максимальная компактность и гибкость:
- Краткий код + дизайн-шаблоны
- Целостность
- Коллаборативный видеомонтаж
- Максимальная компактность и гибкость:
If the product is used as a tool, its interface should be as unintelligent as possible. Stupid is predictable; predictable is learnable; learnable is usable. ©
- Сборка
- Автоматизируемая
- Инкрементальное обновление
- Переносимость проекта (абсолютные пути в видеоредакторах)
- Прозрачность
- Масштабируемая
- Сборка/по сети
- вся [ночная]-мощь компьютеров компании.
- Сборка/по сети
- Free & open-source.

- Необходимо
- AVISynth, 32bit, >= 2.6.0
- Скачать SA.EXE, положить в любой каталог, включенный в PATH.
- Очень желательно, практически обязательно, если не уверены в обратном (для видеоверстки)
- Кодек x264vfw 32-бит (даже, если Win764bit)
- Другие кодеки по источникам (Cedocida для DV и т.п.).
- Inkscape
- VLC
- Рекомендую
- ConferenceRecorder или просто Screen2Log для скринкастов.
