When watching back my first flight test footage, it seemed to stutter quite a bit. (4k 30fps) So, I noticed the stutter was consistent in certain parts of the video (during a slow pan). Opened the video in Adobe Premiere, advanced frame-by-frame. Sure enough, at the point of stutter, there are 2 consecutive video frames. The inspire USES THE SAME FRAME as the previous, perhaps if it cannot keep up? This is using the included SD card. If I delete the rogue frame, that section of video looks normal again. Computer too slow? No - Core i7, GeForce GTX 680. SD card to slow? This SD card came WITH the Inspire. Video was copied to an SSD, same result. Converted video to 1080p to rule out performance issue, no change. This makes the video look like crap. I encourage you to test your footage frame-by-frame if you are suspicious, and report similar findings.
