I'm curious about the experience of others who have tried to take video with their D4 cameras. I've experienced some unexpected bumps along the way:
1) Some of my movie segments have been smooth, but a few show a pronounced stutter, or interrupted flow in both video and audio. I encountered this in darker indoor settings. I noticed that the camera was struggling to stay in focus; perhaps that interrupted the audio-video quality.
2) The ISO for the still camera goes up to 12,800 but I was only able to get ISO 400 or less in video mode, despite an effort to make a manual adjustment. I did not see that mentioned in the D4 technical specs.
3) The D4 offers the opportunity to clip still frames out of movie sequences. Unfortunately, these images seem to have a resolution of only 1mb, which is less than ideal for enlargement.
If anyone else encountered these issues and found solutions, I'll be interested!
