CAM File

What are CAM files and how to open them

Are you having problems opening a CAM file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your CAM files.

What is a CAM file?

CAM files have multiple uses, and Casio QV Digital Camera Image is one of them. Read more about the other uses further down the page.

Casio QV Digital Camera Image File

The CAM file format is used for an image file type created by Casio for one of their digital camera product models in the mid-1990s. Also known as Casio QV digital camera image files, files in this format use the .cam file extension.

Casio QV digital cameras generate these CAM image files. A .cam file contains bitmap graphics and digital photos taken using a Casio QV digital camera.

The Bitberry File Opener software, which is a program for Windows PCs, can be used to open and view these CAM files. In addition, other photo editing applications and bitmap graphics authoring programs for both Windows PCs and Mac OS X computers may be used to open and view the digital image content of these CAM files. These applications may also be used to export these .cam files to other more standard image formats like JPG, BMP, and so on.

How to open CAM files

We have identified three CAM openers that are compatible with this specific type of CAM file.

All known file formats using extension .CAM

While Casio QV Digital Camera Image File is a popular type of CAM-file, we know of 8 different uses of the .CAM file extension. Different software may use files with the same extension for different types of data.

Aegis ProMotion/Videoscape 3D Camera File

Aegis ProMotion/Videoscape is a 3D video animation software for the Commodore Amiga home computer.

While we have not verified the apps ourselves yet, our users have suggested ten different CAM openers which you will find listed below.

Air Warrior Camera Replay

Air Warrior Camera Replay files store recordings made by the gun-camera feature in the Air Warrior series of flight-simulator games by Kesmai. These "films" capture all or parts of a flight session, including aircraft movement, radio traffic, viewpoint changes, and external vs cockpit views, and allow playback after the flight or when exiting to the films library.

The recordings are created during gameplay: pressing the camera-key (typically <9>) begins filming, pressing it again stops. Multiple start/stop cycles introduce break points in the recording. Temporary files are assigned sequential character names (for example Film0000.cam, Film0001.cam) during a flight. Upon exiting the flight, the player is prompted to save the temporary file into the game's film directory; if not saved, it may be overwritten in subsequent sessions. The player can later choose a saved film and play it, using controls to rewind, fast-forward, change speed, switch between external and in-cockpit views, zoom, or even "enter" the film (take control of the plane while other aircraft fly their recorded paths).

The file format is machine-independent ASCII, storing the filmed data in a way that is not tied to specific processor architectures, so that it can be played back on different systems regardless of speed or platform. Internally, files begin with a distinctive signature in their first bytes: ASCII "AWFILM@!" starting at offset 0 (hex values 41 57 20 46 49 4C 4D 40 21).

Fallout Tactics Campaign

Fallout Tactics Campaign files are used by Fallout Tactics: Brotherhood of Steel to define all the high-level data for a single-player campaign. They are written by the Campaign Editor tool (distributed with version 1.27 of the game) and hold information such as the world map background, placement of missions and bunkers on that map, lists of random, special, and core missions, and configuration for recruits and the quartermaster.

These files are read by the game when selecting or playing a campaign, determining what missions are available where on the map, how often random and special encounters occur, what recruits are unlocked, what inventory the quartermaster offers, and what image is shown as the world map. Changes to campaign content are made by editing an external text version ("campaign.txt" in the game's Tables folder), then importing that data into the Campaign file using Campaign Editor's import functions.

Technically, the file's internal structure begins with header fields storing size of world map in tiles, its dimensions and tile-size in pixels; followed by raw image data for the world map and a movement bitmap, then sections for tile spacers and mission definitions. Various data blocks follow: core missions set positions; special encounters; random encounter definitions; landscape maps used for random events; and prefab character lists. The file can be identified by byte signature ".campaign" at offset 0 and the presence of the string "CAMPAIGN_TILE" somewhere in the file.

Flight Commander 2 Campaign Data

We know that one CAM format is Flight Commander 2 Campaign Data. We have not yet analyzed in detail what these files contain and what they are used for. We're working on it.

Gerber CAM Processor Job

This format is the job specification file used by EAGLE's CAM Processor to automate the export of manufacturing-related data (Gerber files, drill files, silkscreen, masks, etc.) from a PCB board layout. It defines a "job" made of one or more named sections, each section specifying which board layers to include in an output file, what output device/format (e.g. Gerber RS-274X, Excellon drill), how to name the output files (including placeholders for board name and layer), and optional transformations like mirroring, rotating, scaling and offsets. The job file lets a user set up all required files beforehand so that with one command ("Process Job") EAGLE generates the full set automatically.

The file is plain text, editable, and uses specific keywords (such as Section, Layers, Device, Scale, Offset, Output, etc.) that correspond to the fields in each section. When exporting, EAGLE processes each section in order, generating output files according to the specified Device (e.g. GERBER_RS274X, EXCELLON etc.) and filename patterns, using any placeholders defined in the job file. Users often start from existing job files like "gerb274x.cam" or "excellon.cam", then modify or add sections as needed.

Internally the format can be recognised by a signature at the very beginning: it starts with the ASCII string "[CAMProcessorJob]" at offset zero. The file also typically contains many of the following keywords: DESCRIPTION, TOLERANCE, EMULATE, SECTION, COLORS, DEVICE, LAYERS, OFFSET, OUTPUT, PROMPT, FLAGS, SCALE, SEC_1, SHEET, WHEEL, NAME, PAGE, RACK.

MSN Messenger Video File

MSN Messenger Video File is a video recording made during webcam conversations in MSN Messenger (and its successors such as Windows Live Messenger or aMSN). It stores the video stream encoded in the ML20 codec when two users use the webcam feature in chat. Such files are useful for preserving or reviewing frozen video chats from older MSN-style instant messaging systems.

The file is created by recording tools built into Messenger or by related utilities like MSN Webcam Recorder, Mercury Messenger, or Mercury's "Webcam Recorder" feature. After creation the file can be played back for review, or converted into more common video formats using tools that support the ML20 codec.

The ML20 video codec encodes video in native YUV 4:2:0 color space, using both intraframes and interframes. The encoding uses 8×8 blocks per color plane (Y, U, V, in YVU order). Intraframes are compressed via discrete cosine transform (DCT), quantization, zigzag ordering, and variable length coding of AC coefficients with runs of zeros. Interframes allow blocks to be copied from previous frames (or from up to 15 earlier frames for luma) when unchanged, otherwise recoding them similarly to intraframes.

These files often include a signature at byte offset 12 consisting of the ASCII string "ML20", identifying the codec in use.

Opticks Camera File

Opticks is a ray-tracing software for the Commodore Amiga home computer.
