ReplayFlow
Practice with a reference video, record yourself, then compare the two side by side.
Import the reference clip you want to practice, slow it down, loop it, or mirror it to see the details. Then record yourself and review it next to the reference.

Practice should not mean switching tools all the time.
A clip moves too fast, the part you need is short, and after recording you have to find the reference again. Those little interruptions make practice feel fragmented.
- Want to repeat a few seconds but keep missing the right place?
- Forget the move as soon as you switch from the video to the camera?
- Have to find the reference video again after you record?
ReplayFlow puts those steps into one repeatable practice flow.
Three steps. One practice session.
Start with the few seconds you want to practice. Study them, follow along, then review both videos together.
Record while watching the reference
Keep the reference on screen, follow along, and record your own version at the same time.
Review side by side right away
When recording ends, go straight to a synced comparison of timing, direction, and positioning.
Already recorded? Choose an existing practice video instead. You do not have to record again.
Learn about imported comparisonsWhile practicing
Keep the reference in view while you record.
The reference and camera are visible together. Follow the move while you practice and record—without jumping between apps.
- Choose picture-in-picture, top-and-bottom, or side-by-side layouts.
- Set a countdown, choose a camera, zoom, and focus before recording.
Two ways to compare
Choose the right view. See the difference.
Record yourself or choose an existing practice video, then review it in sync with the reference. Compare directly instead of relying on memory, with slow motion and frame stepping when needed.
- Record in the app and go straight to a synced comparison when you finish.
- Choose an existing video and align it manually; it is used only for the current comparison.
- Switch among stacked, side-by-side, and picture-in-picture views, and play the reference audio, practice audio, or neither.
Slow down complex parts and break them down clearly.
Use slow motion, looping, frame-by-frame review, and mirroring to study the details. Crop the frame and organize the segments you practice often, then pick up where you left off. Export a video whenever you need it.
Loop a segment
Mark the segment you want to repeat and keep playback within that range.
Slow motion
Slow the reference down to see timing, balance, and direction more clearly.
Frame stepping
Pause and move one frame at a time to check position and timing.
Mirror practice
Flip the reference video horizontally so you can practice in the same direction more easily.
Crop the frame
Crop out distractions to focus on the movement you want to practice.
Save and organize
Name, categorize, and save the segments you practice often so you can get back to them faster.
Build your practice library
Come back to your saved segments and settings.
Saved segments keep their A/B range, playback speed, mirroring, and mute settings. Name and categorize your videos and segments to find the ones you practice often.
