My friends and I are recording a project for school on my apple iphone 7. I have edited my video and everything, and when i go to render it will get about near to mid way with rendering and then it would just go black. Please help!!!
Try losslessly rewrapping your iPhone .mov files to .mp4 files with ffmpeg. They will behave better in Vegas. See this post and the one below it. You could may be able to make this process more user-friendly with an ffmpeg GUI such as ffe. There are many others.
