Video Overlay: Motion Compare
Compare motion, frame by frame
$59.99
One-time purchase, no subscription. Overlay two motion clips, sync the key moment, and scrub in slow motion — the film room that fits in your pocket.
Video Overlay is a pocket film room for comparing motion, side by side or stacked as one overlay.
Load two video clips — the same athlete on two different days, two swings, two pitches, whatever you're trying to compare — and sync them to the exact moment that matters: release, contact, plant, or impact. Then study the difference in slow motion, frame by frame, with both clips always playing from one shared clock.
WHAT'S INCLUDED
• Overlay two clips with independent opacity, or view them side by side
• Sync clips by tapping the same key moment on each, or nudge them by hand
• Play together at 0.25x, 0.5x, 0.75x, or full speed
• Step forward or backward one frame at a time, or jump 5 or 10 frames
• Precision scrubbing timeline with frame number and timecode always visible
• Loop a short window around the key moment
• Capture still frames for coaching notes
• Toggle center, ground, and body-angle guide lines
• Mirror a clip horizontally to compare a lefty to a righty
• Export the finished comparison straight to your Photos library
BUILT FOR ANY SPORT
Baseball pitching mechanics, a golf swing before and after a lesson, a softball swing at contact, a sprinter's stride — Video Overlay works for any motion you can capture on your phone.
PRIVATE BY DESIGN
Your videos never leave your device. Video Overlay has no accounts, no ads, no analytics, and does not collect any data.
ONE PRICE, NO SUBSCRIPTION
Video Overlay is a one-time purchase. Pay once and every feature is unlocked — no trial, no recurring charge, no in-app purchases.
Ratings & Reviews
What's New in Version 1.3
This is our biggest update yet! Video Overlay has a whole new look that puts every control right next to your video, and some powerful new ways to break down every rep.
All-new workspace. Play, step frame by frame, scrub and change speed from one clean control bar right under your video. Your tools sit in simple tabs, one at a time, so the video stays front and center.
Frame-perfect trimming. Trim both clips at once, right down to a single frame. Tap "Match Lengths" and both reps line up to exactly the same length.
Align on the body. In Overlay, line up two reps using body points like the lead foot and head, then fine-tune the timing a frame at a time.
See the numbers in full screen. Full screen now truly fills your iPhone and iPad, and the angle comparison comes with you, so you can see exactly how many degrees changed between two reps.
Save exactly what you see. Save your comparison with the skeleton and angles burned right in, ready to share with athletes and parents.
Beautiful on every screen. A brand-new launch screen and layouts built for iPhone and iPad, in portrait and landscape.
Polished everywhere. Clearer time display, easier-to-tap controls and lots of smaller refinements.
Thank you for coaching with Video Overlay. We can't wait to see what you and your athletes discover!
