I cannot get DVDA to accept any video from Vegas without forcing a re-encode... I started with the 4K MAgix AVC exports I made, expecting to let DVDA produce the BD and DVD encodes, but it wouldn't take those, nothing but black frames. So, I decided to encode a Magix AVC DVD Artchitect preset (23.97p) in Vegas. I did NOT use NVENC because I've read here that DVDA will force re-encoding if you do. Problem is, it forced me to anyway even with Mainconcept CPU encoding (I left the stock DVDA preset alone, no changes were made). So, not wanting to lose much quality on a re-encode, I tried to re-export the avc file as a super high bitrate (135mbps ) file, but when I loaded it into DVDA, it too produced nothing but black frames. So, I tried to encode to a Sony MXF file instead, but it too produced nothing on the DVDA timeline, just black frames.

I was able to get the 135mbps AVC clip to play the very beginning, but then it cuts off a short way into the video.

So, it appears the only option I have left is to do another 25mbps DVD Architect Blu-Ray encode, then let DVDA RE-encode that file again, ruining the quality. I can't find any format DVDA will accept.

Before Vegas 15, I was able to just use the main concept templates and no re-encoding was required. What happened? Magix, please look into this.
