1. If you’re talking about the open-source program, I don’t have it. If you referring to my media information, it’s 2256×1504, and the bitrate is 3649 kbps. Also 60 fps.
2. I use Sony Vegas on two computers, the first one is an HP Pavilion with a Intel(R) Core (TM) 17-4790 CPU @ 3.60 GHz processor with 8 gb of ram. The second is a Microsoft Surface with an Intel(R) Core(TM) 15-7200U CPU @ 2.50GHz 2.71 GHz processor with 4 gb or ram. Both computers experience the same problems when the same video is in Vegas.
I’ve tried all your steps, but nothing worked. Including the reset. Now I’m starting to get a tad bit worried.
