The Sony Cyber-shot RX100 III was one of the best cameras we saw in 2014 and now there’s a new version, the RX100 IV. The RX100 IV offers a 1-inch, 20-megapixel sensor like the RX100 III, but it uses a different technology dubbed “stacked CMOS sensor” and branded Exmor RS. This sensor allows not only a significant improvement in burst capture rate (now up to 16 frames per second at full resolution) and electronic shutter capability up to 1/32,000 second, but also provides 4K video capture, and high frame-rate video at up to a staggering 1,000 frames per second.

The XAVC S 4K (QFHD 3,840×2,160 pixels) footage delivers much clearer image, but may also cause incompatibility issues while editing in Apple iMovie. In this situation, we would recommend transcoding RX100 IV 4K footage to AIC .mov for use in iMovie smoothly. This requires third party software like HD Video Converter for Mac. Read on to find a step-by-step guide talking about how to transcode RX100 IV XAVC S 4K footage to AIC .mov format for working with iMovie.
