| - | ====== Sequences Understanding ====== | ||
| - | |||
| - | ===== IMPORTANT NOTE ===== | ||
| - | This article assumes you're running FreeStyler on a PC using a little endian processor (x86 core) | ||
| - | You may have to consider swapping the data on a big endian processor (ned xcheck) | ||
| - | |||
| - | ===== What is a sequence file (*.chb) ===== | ||
| - | |||
| - | The sequence file is generated by the sequence editor. See [[sequence_editor|the sequence editor]] for further information. | ||
| - | This file contains the DMX values and other informations to allow Freestyler to play back your scenes. | ||
| - | |||
| - | ===== Structure of the sequence file ===== | ||
| - | |||
| - | The sequence file is divided as below: | ||
| - | |||
| - | **Word0:** Number of steps contained in the file | ||
| - | |||
| - | 0x0200: Sequence has 2 steps | ||
| - | |||
| - | Then all steps are added with the following syntax: | ||
| - | |||
| - | all steps are using 1618 words (1 + 1 + 1536 + 79) | ||
| - | |||
| - | **Word1:** Time for the fade (multiplier for 500ms) | ||
| - | 0x0100: (fade time is 500 ms) | ||
| - | 0x0300: (fade time is 1500 ms) | ||
| - | **Word2:** Time for the scene (multiplier for 100 ms) | ||
| - | 0x0A00: (scene time is 1000 ms) | ||
| - | 0x0D00: (scene time is 1300 ms) | ||
| - | **Word3 to Word1539 (included): | ||
| - | * First word is the DMX value for the channel | ||
| - | |||
| - | From 0x0000 to 0xFF00 | ||
| - | (0x0100, 0x0200, …, 0x7F00, 0x8000, …, 0xFE00, 0xFF00) | ||
| - | |||
| - | * Second word is the usage of the DMX channel | ||
| - | |||
| - | 0x0100 = Fade | ||
| - | 0x0200 = Snap | ||
| - | 0x0300 = OFF | ||
| - | |||
| - | * Third word seems to be unused for now | ||
| - | |||
| - | Always 0x0000 | ||
| - | |||
| - | **Word1540 to Word1617 (included): | ||
| - | |||
| - | ===== How can I see/edit the sequence file content ===== | ||
| - | Get an Hex editor such as PSPad for example and open the file in HEX format. | ||
| - | |||
| - | {{: | ||
| - | |||
| - | |||
| - | In this example, the sequence has 5 steps. //0x0500// | ||
| - | |||
| - | **In step1** | ||
| - | * Channel1 is 255 snap //0xFF00 0x0200 0x0000// | ||
| - | * Channel2 is 255 fade //0xFF00 0x0100 0x0000// | ||
| - | * Channel3 is 255 fade //0xFF00 0x0100 0x0000// | ||
| - | * Channel4 is 255 snap //0xFF00 0x0200 0x0000// | ||
| - | * Channel5 is 255 fade //0xFF00 0x0100 0x0000// | ||
| - | * Channel6 is 255 snap //0xFF00 0x0200 0x0000// | ||
| - | * Channel7 is 255 fade //0xFF00 0x0100 0x0000// | ||
| - | * Channel8 is 255 snap //0xFF00 0x0200 0x0000// | ||
| - | * Channel9 and follow are unused | ||
