No need to use interframe compression. Just JPEG will get you around 50x ratios with virtually no discernible artifacts at pixel densities that high (for mostly-text input). And there's no slow-motion about it; the whole point of compressing is to allow for very high framerates. If you can't get the E Ink to push 30hz, then there's probably not much reason to use lossy compression anyway. If you can get over 30hz, then lossy compression will keep you from totally saturating the USB 3 bus.
