Vegas, DivX and AAC

I am attempting to render a video that I can stream from my server to my dlna compliant bluray player. The player is a LG BD390. My tests so far indicate I can get better quality for a given bit rate with DivX that other available codecs. But to stream to the BD390, I believe I need to render the audio as AAC.

In Vegas 9c, when I select DivX 6.85 as my Video for Windows format, AAC isn't an available audio codec. I know it is available the audio codec for Sony AVC. Does this mean the AAC in Sony AVC is limited to only that video codec and that I need to acquire an AAC codec that works with DivX, if there is such a thing. I'm new to DivX so I would appreciate your insights on how to proceed with this. Basically I need to render to an avi wrapper using DivX video codec and AAC audio codec.

Try using the DivX 7 encoder. Just render out of Vegas to a format that you can imput (such as mpg2 or another AVI file that the encoder can read).

Jeremy, I have the DivX encoder but I'm hoping I can find a way to render to DivX and AAC firectly from within Vegas.

Vegas uses VFW AVI codecs, which do not support audio encoding that can use VBR, thus AAC is not available, along with a few others.

VFW doesn't understand B-frames either, so it's really pretty crippled by today's standards.

Musicvid, that is very informative. I've heard some grumbling in the past about vegas use of VFW, but didn't understand the implications that brought with it. Out of curiosity, I went to my CS4 Premier Pro (which I don't actually use) and it to uses VFW for accessing codecs that don't provide a custom plugin for PP.

I saw an interesting comment in their Help file:

DivX uses temporal compression which is not suitable for editing. Using DivX files as source clips will cause you a lot of grief. Convert them to “uncompressed AVI” or “DV AVI” before importing them into Premiere Pro.

That interested me because I just finished a project that used DivX source and I had some weird problems with it. Maybe I now know why, because I dkd not convert it.
