So, after some time not using Vegas, once my favorite editor, I upgraded to 15, and did this
- On a new timeline I added a 15 seconds iPhone 1080p 59.94 clip
- Added a Vegas title onto the clip
- Selected File -> Render As
- Magic AVC/AAC MP4
- Internet HD 59.94fps
- Got "An error occurred while creating the media file <file> - The reason for the error could not be determined
Now, using Sony AVC/MVC worked, but seriously guys. I really thought I was going to be able to come back to Vegas on my main PC some time in the future. I am going to continue trying a bit, but at the moment, if I need work done, FCPX and Motion on my MacBook seems to be the user friendly solution. I really don't like to work in Premiere.
