Sony Vegas Pro 13 forgets to render some frames in my video
I know this reply is 4 years past, but hopefully its of some use to someone. But I found that matching your project/raw files to match your output fixes that issue for me personally, so if I have a 1080p30fps raw file, the final render needs so also match 1080p30fps, if you &quot;upscale&quot; to 60 fps, you'll have ungodly render times and paused/skipped frames.
