DVD-A Always re-renders 16:9 files

Either I'm missing something obvious or this is a bug...

Whenever I render video using main concept mpeg2 in Vegas 4 and select a 16:9 aspect ratio from Vegas's custom render menu, DVD-A wants to re-render it when I choose to 'prepare dvd'. Regardless of the aspect ratio of my DVD-A project or the settings I choose in the 'optimize dvd' dialog box, I'm always forced to re-render 16:9 files - which wastes alot of time and lowers the quality.

When I render at 4:3 in Vegas, DVD-A doesn't require me to re-render video even I'm working on a 16:9 project in DVD-A.

Has anyone else seen this

ok, so strangely enough if I render to a 2.2:1 .mpg file using main concept in Vegas 4.0 then DVD-A doesn't want to re-render. But if I use 16:9 then DVD-A always wants to re-render. I know I can render to a 16:9 .avi file and then use that in DVD-A to avoid having to render to mpeg-2 twice, but its kind of a waste of time and disk space.

I just came out here to post the exact same problem. I just spent 2 days encoding a 160 minute video using the "DVD Architect NTSC Video Stream" template. The only setting I changed from the default was to change the Aspect Ratio to 16x9. DVD-A seems to load and preview it fine, but claims that the video needs to be re-encoded. It would be nice if the UI gave some clue as to why.

I tried to load the file in Media Player and it just hung. I tried to load the file in Dazzle's DVD Creator Deluxe, and it says it has a non DVD compliant aspect ratio and needs to be re-encoded. What is odd, is that I encoded the same file in VV 3.0 with 16x9 aspect ratio and I beleive it worked fine in DVD-A without being re-encoded. I've since deleted that file as I decided to re-encode it in VV4. I've done about 30 test encodes in VV4 with various sources and settings. DVD-A claims it needs to re-encode every single one I created with 16x9.

Everything I do is 16x9. My source is several hundred GBs of raw AVI, so I don't have the disk space to have DVD-A encode it all for me. I need to encode portions of it using VV4, then delete the source to make room for different source.

I have just tried a 16:9 clip in DVDA

If I choose optimize and set the properties for the clip to PAL not PAL wide it does not try to recompress the clip.

Not sure of the logic you would expect to choose PAL Wide.

Irrespective of what I set (from Project, PAL or PAL wide) DVD-A reencodes the files. This is unacceptable since I then don't have full control over the encode. This far I have only tested with the MainConcept encoder but this might not be my prefered encoder (I plan to make tests with TmpgEnc and ProCoder and that will not work if DVD-A reencodes my files).

16:9 MPEGs will always be re-encoded... this is, sorry to say, a bug. This problem will be fixed in the very first DVDA update. Until the update is released you are advised to use 16:9 avi source files rather than MPEGs- DVDA will do the encoding to MPEG and the quality will be much higher than a re-encoded MPEG.

We regret that this slipped out.

Thanks for the note - there is nothing worse than spending hours trying to fix something that you can't fix.

SonicEPM - I appreciate your honesty in the matter. To be quite frank, I purchased DVD-A not because of what it can do today, but rather what it will do in the future. I am simply blown away by the features and quality of Vegas that I could not pass up the oppertunity to buy DVD-A. I have struggled with other DVD Authoring apps that were rushed to market with very little testing and an inappropriate number of support staff available to help out. I am sure that over the coming months (and years) that DVD-A will emerge as the premier DVD Authoring application not only because of its price, but also because of its rich and professional feature set.
