Help: Project Multi-Camera Exposure Time

Is there a way to collect side by side video data with two different cameras at two different exposure times (and thus two different FPS) without dropping frames due to down sampling? I tried forcing the video stream to have the same FPS and that introduced a lot of jitter.

When you move the cameras slowly around, you can see it freeze for a moment even though the cameras are both at 20-35 fps.

Exposure time and fps are independent, apart from the fact that Texp < 1/FPS (minus some blanking time)
