Whar Output Format do I Render To from Vegas Pro 13 to get DVD Architect to make an ISO for a 4K Blu Ray ?
No way to do this with the DVDA - since the DVDA is limited to HD.
Is there another program that can be used ? When is the next version of DVDA and Vegas Pro due ? Surely it will be updated for 4K.
There will be authoring tools for UHD/4K for sure. But the question will be the price I think. Beside that most users seems to tend to render to files and stream the files with media player to their UHD displays. Maybe the simple solution, if you can live without menus.
