Exporting CDXL Files: What FileViewPro Can Do

CDXL is a chunk-stream video format from the Amiga era, relying on sequential frame chunks and tiny headers instead of advanced compression like H.

CDXL was intended as a basic, sequential video container to let Amiga computers play footage straight from disk with minimal processing, with "stream-friendly" signifying that chunks are ordered for smooth, forward-only reading rather than random seeking or heavy decompression, typically using a cycle of small headers and frame data (sometimes audio) that repeats throughout the file, enabling a simple "read → show → repeat" routine suitable for older CD-ROM speeds and limited CPUs.

When CDXL is called a "video container," it reflects that the format wasn’t targeting modern amenities like subtitles, chapters, or deep metadata layers but rather providing a simple wrapper of frames (with optional audio) optimized for fast Amiga playback, whereas MP4/MKV manage many stream types and sophisticated indexing, and CDXL’s lower resolution, slower frame rates, and occasional lack of audio were necessary compromises to guarantee consistent realtime streaming.

CDXL appeared most often wherever Amiga titles wanted to include real video without requiring costly decoding chips, particularly on multimedia-focused systems such as the CDTV and CD32 that shipped discs mixing menus, images, audio, and brief video; developers leaned on CDXL for things like intros, narrative cutscenes, animated segments, and product demos, and its straight-from-disc streaming approach also made it a natural match for edutainment and reference CDs filled with short video snippets.

CDXL also had a place in more professional Amiga multimedia—kiosks, trade-show installations, training discs, and internal corporate or educational productions—because its straightforward playback made it perfect for short looping presentations, and when you encounter a CDXL today it usually comes from an old Amiga CD, intended as a cutscene or interactive-menu video rather than a full modern movie.

A CDXL file is typically arranged as a linear stream of small chunks read in strict order, each starting with a compact header describing how to interpret what follows—details like frame sizing, pixel packing, and sometimes audio flags—followed by the payload containing a full frame’s data (or part of one), with some variants interleaving audio; the player simply reads the next chunk, uses the header to display the frame, and repeats, which avoids the need for complex indexing and suits Amiga-era CD-ROMs designed for continuous forward streaming.
