tubanation

Hi, I am new to this forum. I have been using video pad daily on my pc laptop for quite a while but I really am not an expert. What I do is record music practice videos using OBS studio, I remux them to mp4, and then import them to Videopad where I add reverb and to correct video and audio sync. I then export the video to my pc and upload it to Onedrive, download it from one drive to my phone, then share to instagram. (I do the whole upload part because instagram videos have to be over a minute to upload from a pc). Starting a couple of days ago something changed. After uploading the video to Onedrive (I have also tried Google Drive with the same results) the video will not play correctly, even though it played fine on my pc before the upload. I get a message from one drive saying Video can not be played at this time. It gives to option to play the video with another app like Video Player, but when I do that the audio plays fine but the video is frozen on the first frame. If I upload my mp4 to onedrive skipping the videopad part everything is fine. I must have accidentally changed some setting of is this something else? Any thoughts
