Imagine if they do this with the A7sii. If they use the same type of sensor as in the A7s, they could get 20, maybe 30 stops of DR. Lol.
There are good algorithms to rebuild the missing lines without aliasing.
The decision to do it well will be more related to market strategies, give to the low budget people a good hdr image or keep the aliasing free image for expensive cameras.
the 24 megapixel sensor is 6000 x 4000. If they crop the video recording to 5760 x 3240 each exposure will be 5760 x 1620. 5760 is 1920 x 3 and 1620 is 1080 x 1.5, this resolution in a full sensor readout is good maths for a good reconstruction.
if they build a sensor with 33 megapixels so they can do 7680 x 4230 pixels for video recording and each exposure will be 7680 x 2160 enough for 4k hdr or even 8k hdr, but I do not believe they will do this now, maybe in the future.
in doom9 forum they have the QTGMC deinterlace which proves that a aliasing free reconstruction is possible. they just need to be willing to do it, with a powerfull processor in the camera with theys own algorithms, not the QTGMC because it is slow processing.
