MultiAngleVideoPlayer

This is the most important chapter in the manual. None of it is obvious from looking at the interface, and everything else in the app makes sense once these ideas do. If you read only one chapter, read this one.

Some footage arrives as a single file with the camera angles recorded back to back — angle 1 plays, then angle 2, then angle 3, all in one video. To review those angles side by side you first need them as separate files, one per tile. This app can do that split for you, inside the app, without any external editing tool, and without ever changing the original file.

The app holds up to four videos at once, one per tile. There are four ways to load them. All of them need Unlock Mode — in Lock Mode the videos are treated as one aligned group, and adding to the group mid-review isn't allowed (the app tells you so in the status display if you try).

The transport bar at the bottom of the window is mission control. Its left-hand buttons change with the mode; everything from the scan buttons rightward is the same in both modes.

This chapter describes a real operational issue, not a rare edge case. If you run four tiles of high-resolution video on a busy machine, read it — the symptom looks exactly like an app fault but isn't, and knowing what it is saves a lot of confusion.

Race review is a lot of play–pause–step–step–step. Doing that from the spare buttons of a many-buttoned mouse — one-handed, eyes on the video — is the point of this feature: map a Razer mouse's extra buttons to transport actions.

The gear button in the top-right tool cluster opens the Settings window: a filterable list of name/value pairs with an edit panel, in the same style as the track database.

The app narrates what it's doing — load results, alignment notes, warnings, save confirmations, clipboard copies — so you're never left guessing whether something worked.
