Did my first set of flights yesterday using the latest firmware from early April and I do not see anything as an improvement. I get video glitches in about a third of the flights and when I do it's usually a single glitch per flight. My first flight with the latest firmware I had 13 video defects in that single 16 minute flight. I'm working to upload the video and hope to have that done later today at which time I'll report back to let you know. These 13 defects are not all the same type of defect and in fact I count 3 or 4 different defects types.
The first defect is a jump, forward or back, of about 1 second and this happened 7 times. The second defect, a tearing of the image lasting a second or two, occurred 5 times. The third defect is a large blocking up of the video where the entire right third or so of the video changes color relative to the rest of the video. This isn't the banding we see in the sky but something entirely different. This defect started at the 13:00 mark and continued 3 minutes until the end of the video. The forth defect, the color shift, is related to the previous defect and so perhaps defect 3 and four should be lumped together.
I flew 2 more flights yesterday and I don't think I saw any of these defect in either of the other 2 videos -- I've had the first 2 defects in previous flights using earlier firmware going back to early December so clearly these issues have not been fixed. With prior firmware these defects would usually show up in about 30%-40% of the flights and in most cases there was just a single instance of the defect in that flight though there have been a few flights with 2 or at most 3 defects per flight so to go from that to 13 defects in a single flight is a problem.
The settings used were: 4K30 (UHD), ISO100, f/5.6, SS 1/1000, WB=6000, D-Cinelike, -1,0,-1, MP4, and H.265.
