I can't seem to get an answer to my question. Maybe you can help me? The video footage I take on either my DJI Osmo or DJI Phantom 3 Professional at either 4k or 1080p is very good as expected, but after I do a simple edit like shorting the clip or clips in iMovie the exported video is poorer quality...significantly. How can I fix this? Do I need to get a better editor?
