Author here. Synchronization is an issue I forgot to mention, I guess that's because it's the first problem I addressed. Right now I'm shooting indoors so I just switch lights on/off at some point in the video and then synchronize the videos over the average between the maximum changes of luminance with a simple python script. It's not a generic solution and the accuracy you get is not very high, but it's simple and it works well enough for a first test. Resolution at 30fps is 3840x2160 pixels for the A77, but yes it's probably upscaled. Again at this point I am not too concerned about resolution at this point.
