Streamlined Workflow

Compare → Inspect → Select → Export

From importing media to selecting keepers and dragging to export, everything runs smoothly in one dedicated macOS workspace.

Side-by-Side Compare

Drop folders or files in. Arrange 2–6 images and videos into clean grid layouts without resizing windows manually.

Frame-by-Frame Inspect

Pan and zoom in lockstep across all views. Sync video playback to exact frames with single-key step controls.

Precise Select

Pin winning variants and collect them into the built-in Tray as you review, keeping decisions organized.

Direct Drag-to-Export

Drag selected files directly from the Tray into Finder, editing software, or sharing folders without extra export dialogs.

Why FrameSight

Stop Switching Between Windows

Why not just use macOS Finder, Preview, or QuickTime? Because professional review requires zero-friction comparison.

Traditional Multi-Window Friction

• Open multiple Preview or QuickTime windows and manually tile them across displays
• Zoom into one image, then manually scroll and zoom all other windows to find the same spot
• Manually drag video scrubbers, constantly missing exact frame alignment
• Cycle through Cmd + Tab repeatedly with flickers that tire your eyes and confuse variants
• Remember the winners mentally, then search Finder folders to copy them manually

Average: 10–15 minutes per review session with high eye fatigue

FrameSight Professional Review

✓ One drag imports all. 2–6 assets auto-arrange into clean, focused comparison grids
✓ Synchronized zoom & pan: zoom into one detail, and all windows track identically
✓ Frame-locked video playback: play, pause, seek, and step frame by frame in absolute sync
✓ Side-by-side clarity: instantly discern subtle sharpening, noise, and color variance
✓ Collect winners directly into the Tray and drag straight into Finder to deliver

Outcome: Turn a 10-minute comparison chore into 10 seconds of clear verification

Frequently Asked Questions

Everything You Need to Know

How is FrameSight different from macOS Preview or QuickTime?

Preview and QuickTime are designed for single-file viewing. FrameSight Pro is custom-engineered for side-by-side comparison workflows: auto-tiling 2–6 media items, synchronized pan and zoom, frame-locked video sync, single-key frame stepping, and direct drag-and-drop export from an integrated Tray.

See the full comparison with Preview and QuickTime →

What file formats are supported?

Images: JPEG, PNG, HEIC, TIFF, WebP, AVIF, GIF, BMP, and JPEG 2000, plus DNG (RAW) and PSD with Pro. Videos: MOV, MP4, and M4V using codecs macOS decodes natively — H.264, HEVC (H.265), and Apple ProRes, plus AV1 on Macs with hardware AV1 decoding (Apple M3 or later).

Are my media files uploaded to any servers?

Never. FrameSight Pro operates 100% locally within the strict macOS App Sandbox. All decoding, playback, and rendering happen on-device. Zero personal or media data is collected or transmitted.

How does the 14-day free trial work?

FrameSight Pro is free to download and includes a free Lite tier for 2-way comparison. To unlock Pro — 3–6 way comparison, DNG (RAW) and PSD support, and more — start the 14-day free trial of the yearly subscription inside the app. The trial is billed and managed by Apple: unless you cancel in your App Store account settings at least 24 hours before it ends, it renews as a paid yearly subscription. Monthly and one-time lifetime options are also available.

What are the minimum system requirements?

Requires macOS 13.0 (Ventura) or later. Runs natively on both Apple Silicon and Intel-based Macs.
