This is my first post. Sorry if I mess anything up. OK....I've been using VRD since 2006. Purchased several "upgrade" licenses since, now running Ver 6. What gets me is that even after all these years using this program for simple trimming of videos, it's still VERY buggy. What's now got me pulling the last few hairs from my head is it's failure to render simple cuts using video taken from my new DJI Mavic Mini Drone! They are MP4 files. Two resolutions are available to shoot. Regular 1920x1080 and 2720x1530. Drone has NO microphone, so no audio. I CAN work with the regular full HD size ok. I can do nearly anything I want, including lowering the bitrate and generating a new clip just fine. BUT when I try the 2700x1500 size, full fail! All I have to do is simply try to render a simple cut from the source file and hit save, BOOM! The progression box shows up for like 700ms then gone! Program does NOT crash, just the progression box disappears. No error or anything. In the past, many files from other sources will crash VRD and the whole program just goes bye bye! Poof, gone! Very frustrating to say the least. I am NOT a video guru, ok? So, I am asking for suggestions as to what may be wrong here.
