EmConvert

Introduction

EmConvert is a utility to convert sequences of image files to uncompressed Replay files. By use of one of the compressors in the Replay starter kit they can then be converted into a compressed movie that can be played on any machine.

EmConvert includes the facility to crop and scale the input frames so that best use of the source data can be made.

Input formats

EmConvert can accept data in the following formats

  1. Text file
  2. Directory tree
  3. Sprite file
  4. ViA file

Text file

The text file should contain a list of file names. Each image should be the same size and format and will be used in the order they appear in the file.

Directory tree

The files in the directory tree should all be the same size and format. The tree is scanned in alphabetical order, descending to lower levels at the appropriate points.

Sprite file

All the sprites in the file should be the same size and format. The sprites are used in the order they appear in the file.

ViA file

This file type was created by the Irlam Instruments ReplayDIY software (version 1). Scaling and cropping is not available when converting this file type.

Image formats

Acorn's ChangeFSI application is used to preprocess the image files before scaling and cropping in cases where the file is not handled internally, thus any format that ChangeFSI can handle can be processed.

Requirements

The conversion process is multi-tasking but may well use up a large amount of memory, especially if the frames are large.
