Review and compare videos faster on macOS

Stop opening clips one by one just to check differences.

Video Multi-Player lets you load a folder once and instantly watch 1 to 4 videos side by side in a clean native macOS interface. Whether you're comparing takes, reviewing exports, checking alternate versions, or scanning a folder of footage, it gives you a faster way to see more without jumping between windows.

Why this is useful

When you are reviewing video files, the slowest part is usually not playback. It is the constant switching:

open a clip
compare it with another
go back to the folder
open the next file
try to remember what changed

Video Multi-Player removes that friction by turning your folder into a simple comparison workspace.

You can move through videos in pages, display multiple files at once, switch between sequential and random review modes, and keep playback looping while you focus on what actually matters: the footage.

Best use cases

Compare alternate takes

Review multiple takes side by side to spot differences in framing, movement, pacing, timing, or performance.

QA video exports

Check several export versions at once to catch subtitle issues, compression artifacts, color shifts, aspect-ratio problems, or timing inconsistencies.

Review motion tests and iterations

If you create animations, product demos, reels, or social content, this makes it much easier to compare versions without repeatedly opening and closing files.

Scan large folders more efficiently

Open a folder once and move through your library in a structured flow instead of manually launching every clip.

Study reference footage

Useful for editors, motion designers, researchers, students, and creators who need to analyze several clips in parallel.

Core features

1 to 4 simultaneous videos

Choose how many videos you want to display at the same time. The layout automatically adapts into a clean grid for side-by-side viewing.

Sequential mode

Move through your folder in a stable, predictable order when you want a consistent review workflow.

Random mode with reshuffle

Generate a shuffled queue for a fresh review session, then reshuffle again whenever you want a new order.

Fast page-based navigation

Use Prev / Next controls to move through the library by the current visible group size instead of opening files one by one.

Keyboard shortcuts

Navigate with the left and right arrow keys for faster hands-on review.

Click-to-jump sidebar

See the loaded videos in a sidebar and jump directly to the page that contains a specific clip.

Automatic looping playback

Each video loops automatically, making it easier to spot small differences and repeat sections without extra clicks.
