This is really neat! I am looking at the footage from the A77 on Youtube. The resolution doesn't seem to be 4K. Apeman seems to do a lot of software upscaling.

I am looking at the footage from the A77 on Youtube. The resolution doesn't seem to be 4K. Apeman seems to do a lot of software upscaling. Their highest-end model, the A100, claims 20MP resolution, 4K video, and an Panasonic MN34120 sensor.
Panasonic claims 16MP resolution -- so 4MP less than Apeman claims, and a maximum of 22fps at 4k. This isn't a linear slide, and I think the best Apeman could do is grab 1080p at 30fps and upscale.

The A77 doesn't say what chip it uses, but it's a model down. And looking at two Youtube videos, I'd say it's grabbing at best 720p and upscaling, likely less, but most of the video has enough action that I could be wrong (compression relics do things as well when scenes change quickly).
OP: Can you post some video frames and see if this setup works as claimed? If it does, it'd be really neat to play with. I'd even be happy with true 1080.
I'd consider this setup more for photos. Lightfield video will be hard without frame-synchronized videos. But once you get photos, one can think about how to invest in videos next.

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.
