Remaps the colours of the original image to the black, white (blue, red/orange) colours.

Normalizes the pictures as the pictures need to be fairly bright or they are hard to make out on the CoCo screen.

Handles picture levels (black, white and gamma controls).

Resizes the pictures to 128×192 (necessary for making artifacts).

ImageMagick is used to do the following things: Next the script uses a picture processing tool called ImageMagick. The images are stored in a folder called pics and are compress LZW – TIFF images. It outputs the scaled video as individual still frames/images and numbers them as it produces them. The format that FFMPEG outputs is 256×192 and will automatically generate black bars on the screen if needed.

It also scales the input video width and height so that the aspect ratio is perfect for the CoCo PMODE 4 screen. It will take just about any video or audio file as input and convert with filters and effects to many other formats.įirst I use FFMPEG to set the frames per second to 23.3 which the CSM player requires. The videos can be found here and here, don’t mind the mess on the floor, I usually have my CoCo 3 hooked up but wanted to show this on an actual CoCo model 1 with a 6309 CPU and 64k of RAM.įirst we use a fairly recent version of FFMPEG, which is the most amazing video and audio conversion tool there is. As an example of what you can expect from this video conversion I’ve uploaded two youtube videos showing the player on a CoCo 1. Below I’m going to explain how this all works and how you can make your own. Using some awesome free tools a bash script and a little C program I wrote it’s possible to make PMODE 4 colour videos that playback at 23.3 fps with sound and have four colours – black, white, and the two artifact colours blue and red/orange.
