The complete matrix
A split for every review.
Portrait or landscape, one clip or nine. NinePlay treats 2 × 1 and 1 × 2 as different tools because orientation changes what you can see.

Privacy is the architecture
Your footage never needs to leave the field.
Videos decode on your device. NinePlay does not upload selected footage or saved sessions to its servers, so private training clips, road footage, and work files stay under your control.
