I was trying to save a step during my DVD authoring and rendered my project out to AVCHD with AC3 audio. I have been using TMPGenc to author DVDs for years now, and noticed that when I added the videos to the project they seemed to think about it a while before finally accepting the file. After I had built my menus and what-not, I started the encode only to have it pop up with an error saying that the format was wrong. I am going to hate to have to re-render this entire project, but it's looking like that is going to be the case. Any ideas?

What is the workflow you used prior to trying AVCHD? And what NLE software do you use?

AVCHD is the very last thing I would ever use as an "intermediate" file - it's very highly compressed. If you're wanting TMPGenc to create the MPEG-2 DVD file from your finished clip, I'd use an .avi codec with 4:2:2 color as the intermediate that is exported from the NLE.

Thanks

I always use a intermediate codec (hqavi) from edius which give me a fast and very reliable workflow in tmpgenc.
