How ReelMarkr works

Everything happens on your machine. No cloud account, no upload, no hidden database. Your work is ordinary files in predictable places.

The two places data lives

1. Next to your footage. Anything tied to a clip travels with that clip, in a ReelMarkr_data folder beside it:

• Notes / markers: ReelMarkr_data/Markers/<clip>.markers.json
• Takes: ReelMarkr_data/Takes/<clip>.takes.json
• Screenshots: a Screenshots folder (configurable, see below)
• Canvas boards: by default, .rmic boards save to ReelMarkr_data/ImmersionCanvas next to the footage

Copy a project folder to a drive or a NAS and the notes, takes, and boards come along. All three apps read the same files, so a note made in RM Player appears in the full app and on the canvas.

2. The app’s own data folder. Machine-local settings and caches: on Windows %LOCALAPPDATA%\ReelMarkr\ReelMarkr_data\, on macOS ~/Library/Application Support/ReelMarkr/:

What	File / folder
Main settings (colors, folders, options)	settings.json
Immersion Canvas settings	imc_settings.json
Notes/markers index	data.db
Thumbnail cache	thumbnails/
Color presets	presets/
Watermark images	watermarks/
Default export output	Exports/
Logs	logs/

Deleting this folder resets the app without touching any footage, notes, or boards.

Choosing where screenshots go

Settings ▸ Export controls the stills workflow. RM Player and the full app share these keys, so set it once:

• Location: a Screenshots folder next to the media (default), or a custom root folder where every screenshot lands.
• Organization: keep everything flat, or organize per video so each clip’s grabs get their own subfolder.

Screenshots are frame-numbered, so every grab stays tied to its exact frame. See Stills gallery & screenshots.

The canvas project folder

Saving a board creates a self-contained project folder named after your board:

Canvas_<name>/
    <name>.rmic        the board itself
    Screenshots/       PNG exports and grabs
    Pasted/            images you pasted from the clipboard
    Audio/             recorded voice memos and audio
    Docs/              documents created on the board
    Moodboards/        moodboard stills
    Tasks/             task-list data

Subfolders appear as you use the matching features. Pick the location at first save or Save As. The default is ReelMarkr_data/ImmersionCanvas next to your footage; set your own default save location from the canvas top bar.

Pasted images

Ctrl + V images are written to disk immediately. Before the first save they stage in the app-data folder; when you save the board they move into Canvas_<name>/Pasted/ and travel with the project.

Keeping a board self-contained (important for shared storage)

Media dragged in from elsewhere is referenced in place by default: the board points at the original rather than copying it. So the Canvas_<name>/ folder alone is not the whole board. Move it to a NAS or send it to a teammate and externally-referenced media won’t come along.

To make the folder self-contained, right-click a node ▸ Copy to shared folder. The file is copied into the canvas folder and the board re-points to that copy. Do it for items that came from outside the project, or flip the Settings toggle that copies imports automatically (they land in an Imports_<user>/ folder inside the project). If the board is leaving your machine, copy to shared first.

Where templates live

Canvas templates (Ctrl + Shift + T) are saved on your machine. Point the canvas at a custom templates folder in its Settings to keep them on shared storage and share a library with a team. Portable .prmic clusters are files: save them anywhere, send them to anyone.

The AI stack is local too

Image generation runs on your GPU. Its heavyweight Python packages (PyTorch, Diffusers, Transformers) are not in the installer: the in-app Requirements dialog downloads them into a private runtime at %LOCALAPPDATA%\ReelMarkr\python_runtime\ on first use. Models live on disk, with a configurable models folder. See Local AI setup.

Resetting

Quit the apps and delete the app-data folder above for a fresh install. Your footage-side ReelMarkr_data folders stay untouched until you delete them yourself.
