I am going to borrow a Sony FDR-AX100 and can choose to shoot some footage in 1080p or 4K. I do not have a need for 4K right now, though if I shoot it in 4K I would edit it and downconvert it to 1080p so I could always go back to the master footage and re-export in the future at 4k.
1. Will CS6 ingest 4K footage from this camera?
2. Will I have any issues editing the footage and just exporting as h.264 1080p when I'm done?
