When you create a combined recording with multiple participants in the Editor, Riverside lets you export the final composited video with a higher resolution than the individual recorded tracks in it.
Depending on how you customize it, the Editor effectively increases the resolution of the final video. For example, if you combine multiple video tracks in a square, Riverside crops each slightly and adds them to a grid. Together, the tracks are arranged in the export with a greater height than the individual tracks.
By displaying each track at a smaller scale than the recorded video, the effective resolution increases while maintaining sharpness and detail.
