I like DVD Architect just fine, but I prefer Encore CS4 because of its easier integration with Photoshop. Problem is, Vegas exports markers that are read by DVDA, but not Encore. Is there any way to do this other than switching back and forth between them?
I've been using sub files as sort of crude markers. Place region markers where you need them then use the "export regions as subtitles" script. Import this to Encore. (Encore can't 'see' .sub files... it's looking for .txt files.... just click "all files" for file type then click on the .sub file).
I will add though that Encores subtitling system is a bit of a pain to work with when compared to dvda.
I just found a script export markers as SRT subtitles which allowed me to get my regions into TMPGEnc Authoring Works as subtitles. Maybe it will work for Encore too. Apparently it's good for closed captions in YouTube also.
A very useful addition to my script menu!
Edit: Version 1.1 of this script has a bug whereby subtitle numbers 100-109 come out numbered as 10-19. Likewise 200-209. Very easy to manually add a zero into the numbers in the .srt file but I'll contact the author about it.
I like the fact that it doesn't let you screw up a project as easily as DVDA does. It's more user-friendly in that sense. It's pretty powerful the interface isn't the most logical so some of the commands can be difficult to find. However if you're making DVDs to a "formula" then it's very fast to get a DVD or Blu-ray authored once you've got your preferences and template set up.
It's super-robust. It nor its predecessor TMPGEnc DVD Author have never crashed or even glitched on me. And the DVDs it produces seem very compliant (e.g. No error messages from PcgEdit like DVDA projects give).
The biggest disadvantage for me is that there are only 2 subtitle tracks.
... and the big ADVANTAGE of TMPGEnc Authoring Works for me is that it will use my HDV file (1080-60i) as is for a Blu-ray project, i.e. smart render, whereas DVDA re-renders.
There is another bug in that SRT subtitle script that I'm working with the author on fixing then publishing. In the meantime if anyone wants a near-perfect copy, send me a PM.
