Dual View

To compare two media items side by side, create a Dual View setup via right-click in the Dual View bin or File > New Dual View.

The setup has LEFT and RIGHT tracks. Drag media into each track, or drop it directly into the viewport. If image sequences are loaded, each will have its own cache progress bar.

How frame sync works: Both media items are decoded in parallel and written to a shared memory-mapped texture. Each side of the viewer UV-maps to its half of that texture, which guarantees accurate frame alignment. Sync is time-based rather than frame-based, so media with different frame rates will align by timestamp.
