# Video Processing Guide

# About this document

The Video Processing Guide describes how to prepare and process video materials into digital video clips for 3DO (tm) title development, discusses hardware options, and suggests a number of software solutions.

# Audience

This document is for 3DO developers-including programmers, video specialists, graphic artists, and project managers-who want to use digital video in a title.

# How this document is organized

- Video Preparation Overview summarizes major steps in video preparation and indicates appropriate chapters. A flowchart of the process is included.

- Selecting Hardware discusses possible hardware combinations and costs.

- Capturing and Processing Materials explains how to prepare materials for capture, how to capture them, and how to process them in preparation for compression.

- Compressing and Playing Your Movie discusses compression, decompression, and related issues.

- Video Tools covers the video processing tools provided or supported by 3DO. These include:

  - The 3-2 Pulldown tool for processing video that was originally based on film.

  - MovieCompress for compressing movies using Apple QuickTime codecs. MovieCompress lets you specify frame rate, key frame rate, data rate,

  - Quality, depth, and codec. It also offers a drag-and-drop feature for opening a movie file, and is AppleScript-scriptable for the four standard events (Open, OpenDoc, Quit, Save).

  - ConvertToMovie, a third-party tool with functionality similar to that of MovieCompress.

  - MovieEdit, which lets you play and edit QuickTime movies. Dynamic displays of time code, time unit, and frame number information give users greater flexibility and precision in editing movies.

  - MovieProcess and MovieProcess PPC (both in the Pioneers folder of this release), which deinterlaces to 20 frames per second (fps), offers variable save options for archiving during different stages of processing, and is scriptable with AppleScript for the four standard events (Open, OpenDoc, Quit, Save).

- EZ Squeeze describes a new 3DO video compression codec found in the Pioneers folder of Toolkit 1.5.
