My videos are recorded in 720p, 30fps. When I edit them in MM and save it, the new video is of a lower resolution. Yes, I have the latest version of MM. Yes, I have created a custom profile that matches the original video's output. I'm using Windows 10. I have tried pretty much every different solution and most of them say to create a new custom profile and it doesn't matter bit rate I set it to, whether it match the original video's or just be put to max, the video's always come out the same, in what appears to be a 360/480p video.

The custom profile I have made sets the bitrate at 6000 kbps. The video comes out at 4984, at least that's what it says when I right click the video and view "Properties". How do I get it to stop downgrading? 

Thanks.
