compareMatik puts 2 to 9 videos or photos side by side on your computer and plays them frame by frame, in perfect sync, so you see exactly what changed between versions, takes, grades or AI models. Stop on any frame, zoom to the pixel, mark it up and paste it into a chat.
Side-by-side video & photo comparison · Mac & Windows
For editors, colourists, VFX and AI-video artists. Two grades of one shot, two upscales, nine renders of the same prompt from different models: drop them in, and the difference shows. Try the wipe on the right: it's a paper model of the real thing.

Every feature · most important first
01Sync
Drop 2 to 9 videos or photos onto the window. Different frame rates, sizes and lengths are fine. One master clock drives every pane, so whether you play, pause, scrub or step, they all show the same frame. Give a clip an offset and it stays locked from there.
Space Play / pauseJKL reverse · stop · forward←→ one frame⌘1⌘2 Row · Grid
Add or remove panes: the grid follows compareMatik's own rule (4 → 2×2, 5–6 → 3×2, 7–9 → 3×3).
02Wipe
Two sources in one picture, split by a divider you drag. A on one side, B on the other: the classic before/after for grades, retouches, denoise and upscales. Press W to turn it horizontal. Pick any two panes as A and B, swap them with ⇧\. Two photos work just as well as two videos.
⌘3 WipeW Wipe orientation⇧\ Swap A/B
03Overlay · Difference · Flicker
Lay B over A with an opacity slider, like an onion skin. Switch the blend to Difference and only what changed lights up; identical pixels go pure black. Or Flicker: A and B alternate every few frames (or every time you press \), and your eye catches the jump at once.
OverlayAB04Copy & paste
⌘C copies the selected pane's frame at full source resolution, with your notes on it. ⇧⌘C copies the whole layout as you see it. It lands on the clipboard as an image, not a file, so it pastes straight into a chat or an email. A small note confirms what went where: pane, timecode, size. You can also drag a frame out to Finder or into a chat window.
⌘C05Annotate
Press D and draw right on the picture: pen, highlighter, arrow, line, rectangle, ellipse and text, in eight colours with a background box so text stays readable on bright footage. A note belongs to the frame it was drawn on and stays glued to the picture through zoom, pan and relayout. Markers on the timeline show where the notes are; ⌥← ⌥→ jump between them.
Your turn: draw on the frame, press ⌘C (or Copy), then paste it anywhere.
06Zoom
Scroll or pinch to zoom from 10 % to 1600 % around the cursor, pixel-accurate at every level. Zoom and pan are linked across panes, so every source shows the very same detail; unlink them when you need to. ⌘0 goes to 100 %, F keeps everything fitted.

07Magnifier · Colour Dropper
Press M and drop a Magnifier (200–1000 %, nearest-neighbour for pixel peeping); it sits on the same spot in every pane. Press E for the Colour Dropper: 8-bit and 10-bit RGB, float, hex and Rec.709 luma, live during playback, read from the decoded source. Click a value to copy it.
Your turn: move over the frame (on a phone, touch and drag). Arrow keys move one pixel, ⇧ ten.
08Timeline
Every source gets its own track. Drag to offset it frame by frame, snap to the playhead, or align everything by source timecode in one click. Set I and O to loop a range. Hide a track, solo its audio, reorder panes by dragging headers.
09Export
Export the pane, the whole layout, or every pane as separate files: PNG (8 or 16-bit) or JPEG, with the colour profile. Render the comparison itself as ProRes, H.264 or HEVC video, In/Out respected, with labels, timecode and info burned in if you like. It uses the same renderer as the viewer, so the file matches the screen. ⌥⌘E repeats the last export in one go.

10Overlays · Guides
The info overlay (N) shows file name, label, resolution, frame rate, codec, bit depth and frame number. The timecode overlay (T) reads the source timecode, drop-frame correct, or counts record-run, frames or seconds. Turn on safe areas and aspect masks: 2.39, 1.85, 16:9, 9:16, 4:5, 1:1, centre cross and thirds.
plate-lightbox.mov · 992×43211LUT · Sharpen
Load .cube LUTs (1D or 3D, up to 65³) for every pane or just one, with a mix slider; they're saved inside the project. A real-time sharpen per pane helps you see whether an upscale really added detail. The colour dropper can read before or after them.
warm-print.cubeLUT mix12Photo Mode
Drop only stills and compareMatik switches to Photo Mode: ← and → flip through the photos. Perfect for picking the best shot of a burst, or checking a set of retouches one after another. JPEG, PNG, HEIC, TIFF, WebP, AVIF and DNG, with EXIF orientation and colour profiles honoured.

13Presentation Mode
⇧⌘P hides every bit of interface and fills the screen with the comparison. Move the mouse and the transport appears; the keys keep working. Made for review calls, client screens and the big monitor in the grading suite.

Save the whole comparison as a .cmk project: media, offsets, layout, notes, LUTs. Moved the footage? Point at the folder and it relinks by name, size and duration.
