I have finally gotten to the point where I have files in my CGO3 4k camera and files from my ST-10. Can someone point me to a place where I can learn how to combine the drone video with the ST-10 video? And how to synchronize the two files? I have been trying to use Dashware but I'm getting errors when I try to load the video file. The data file loads OK. One more question. Is there a way to make mp4 files smaller? I tried 7Z but the file didn't get much smaller. I wanted to email one to my son but even the 5 minute sessions are too big to attach to an email. Thank you very much... Happy New Year!
