I have the FDR-X1000V action cam and sometimes when recording towards the sun the video has a small red dot in the middle of the image. This issue seems to happen more often when I use the hard lens protector or the waterproof case. Is there a video FX that can remove this red dot from my video. I use Movie Studio Platinum 13. I also have the HDR-AZ1 and it does the same thing, so don't think it is a hardware issue.
