The test video was shot with a Sigma 18-35mm which does not communicate with the camera and is a manual focus lens. Seems like it works very well with the GH4.
So I downloaded the 4K Panasonic footage from youtube. My editing system, Edius 5.51 does not do 4k. I dumped the 4k footage into Edius AVCHD Converter and converted it to Edius HQ 1080p .avi file. Is there any benefit to doing this other than being able to edit it? Keep in mind that Edius 5 is 8-bit.
