“Hi, all, I’m planning on buying a Sony RX10 II which is able to shoot 4K footage in XAVC S format. I’m working with iMovie, I have seen that iMovie supports XAVC-S from Sony, but I do not know if 4K XAVC-S is supported too. Any ideas?”

Our quick answer
As far as we know, the most recent version of iMovie can edit 4K in timeline and supports XAVC S. But there are user complains about unstable and unreliable issues. So we still think XAVC S 4K footage is not fully supported by iMovie. If you encounter any problems importing Sony RX10 II XAVC S 4K video to iMovie, we would recommend transcoding them to a format that is best suitable for use in iMovie, such as Apple’s InterMediate Codec, iMovie’s favorite editing codec, which iMovie will recognize and handle well. To process format conversion, third party converter software is required. Considering the ease of use and excellent output quality, we would recommend HD Video Converter for Mac. Read on to find a quick guide on how to convert Sony RX10 II XAVC S 4K files to AIC .mov for iMovie editing.
