<p><b>New page</b></p><div>'''RoQ''' is a full motion video format originally developed for [http://www.mobygames.com/game/dos/11th-hour The 11th Hour] by Graeme Devine. The format was later used as the FMV format for [http://www.mobygames.com/game/windows/quake-iii-arena Quake III: Arena] and derivative games.<br />
<br />
According to excerpts of Devine's ''11th Hour'' development journal published in Wired at [http://www.wired.com/wired/archive/3.08/shipping.html http://www.wired.com/wired/archive/3.08/shipping.html], the RoQ format was named after Devine's newborn daughter, Roqee.<br />
<br />
3DGE implements full support for ROQ, both as triggerable cinematics and rendering to a surface in the game world. A pre-rendered cinematic also replaces the 3DGE splashscreen (inherited from [[1.32]]). The videos can not be compressed into a WAD, but rather in a subfolder named "/cin". This folder name is hard-coded and cannot be changed - 3DGE will always look in this folder if it is present. If the splash cinematic is not found, 3DGE will skip rendering it entirely. <br />

== File Format ==<br />
A RoQ format is comprised of a series of chunks. These chunks may indicate the format signature or playback parameters, or may contain encoded pieces of video frames or audio wave forms.<br />
<br />
=== Chunk Format ===<br />
Each chunk has the following format (all multi-byte numbers are little-endian):<br />
<br />
bytes 0-1 chunk ID<br />
bytes 2-5 length of chunk payload<br />
bytes 6-7 chunk arguments<br />
bytes 8.. chunk payload<br />
<br />
Note that bytes 2-5 only contain the length of the chunk payload, not the entire chunk including the 8-byte header. Also, the RoQ_SIGNATURE chunk contains 0xFFFFFFFF for this field and should only be used for format validation purposes.<br />
<br />
=== 0x1084 - RoQ_SIGNATURE ===<br />
A signature chunk has a length of 0xFFFFFFFF and no payload. The chunk argument represents the movie playback framerate.<br />
<br />
=== 0x1000 - RoQ_QUAD ===<br />
<br />
=== 0x1001 - RoQ_INFO ===<br />
<br />
=== 0x1002 - RoQ_QUAD_CODEBOOK ===<br />
<br />
=== 0x1011 - RoQ_QUAD_VQ ===<br />
<br />
=== 0x1012 - RoQ_JPEG ===<br />
A JPEG chunk contains a plain JFIF file that can be decoded with a standard JPEG image decoder.<br />
<br />
=== 0x1013 - RoQ_HANG ===<br />
The purpose of this chunk type is unclear.<br />
<br />
=== 0x1020 - RoQ_SOUND_MONO ===<br />
<br />
=== 0x1021 - RoQ_SOUND_STEREO ===<br />
<br />
=== 0x1030 - RoQ_PACKET ===<br />
This chunk is known to occur in RoQ files from The 11th Hour. It's use appears to be related to audio processing.<br />
