Hi, Steve,

The current Helix producer uses the audience index to set
the a/v bitrate, we have found a couple of issues that we
like to get some suggestion.

1. The order of audience files is varied for different file
systems on different computer/os, sometimes it even changes
on the same os on the same machine, so the index we set can
actually pointed to different audience files depending on
different installation, which gives us surprising encoding
setting
.  How to make the index fixed for the audience files? Shall
we simply use one audience file we chose and put it into the
directory and move other audience files out of that audience
directory? or there is some better elegant solution?

2. For a single audience, e.g., 256k DSL or cable, it only
encoded upto 225k bps with the split between video and audio
bitrate being 190k for video and 33k for audio (voice).
Question: can we specifically set the split between audio
and video so that our video will take more bits since we
don't care audio that much, for this example, we like to
have the split to be something like 210kbps for video, 15k
bps for audio to get the total 225k bps encoded rm file?

thanks,

Frank

IF I am not mistaken, those audiences can be deleted,
created, overridden
etc, if the user has helix producer.  Thus, you can't rely
on them.

If I do understand what you are saying, you may want to
create some
yourselves and name them after your product.  Then you can
install them
when you install your product.  Thus, you can rely on the
one's you need
to have there, being there....

I'm sure Steve will correct me if I'm wrong about this.....

Thanks,
Brian
