Has anyone else had this problem. I'm using vegas pro 19 I haven't been able to render any 4k videos in hdr10 . Everytime I hit render it says an error occured while creating the media file. The reason for the error could not be determined. It says this message if I try to render in magix AVC/AAC (Mp4) and Magic HEVC/AAC (mp4) but it allows me to render the video in a mov file(apple prores) but the file size are to big to upload to the internet they are 450gb-1tb depending on the length of a video. How do I fix this so I can render it in a mp4 file format without getting an error?!
