Hi All,<br>
<br>
I'd prefer if we keep the audio in stereo too. I try and pan the
audience mic slightly away from centre to give some separation
between the two which give a hint as to who is speaking, and once we
start adding in reverb etc effects we will definitely benefit with
having the signal in stereo.<br>
<br>
Regards,<br>

<div>Also just for a comparison between the x264 and
theora encodes, the x264 average bitrate is 190kbps
with 96kbps audio (very good quality) and video is
almost as good as original DV at full 25fps. Perhaps
there's some magic theora encoding options but it
really just doesn't compete. It's also much slower
at encoding than x264 as it's single threaded...</div>

It may be negligible, but we could possibly drop the audio
bitrate down to mono 48kbps on the x264. I'm interested to
know what the VP8 stuff is like now - its been a year since
we last compared VP8 and x264.</div>

<div>We're only talking 100MB for 1hr 15mins so for x264 we
don't really need to save any more space and I really want the
good quality audio :)</div>

<div>
Yes we should do some more testing with VP8, the git version
of ffmpeg on the laptop has the VP8 codec support built in so
I should be able to do some testing.</div>

<div class="im">We need to have a workshop where we throw
the video into Flumotion. We can define a workflow for
Flumotion to do an on-site encode to a 500 kbps stream,
and send it off-site to another Flumotion host which
transcodes this 500 kbps stream to other protocols at this
bit rate, and also at a much lower bit rate (100 kbps?),
and possibly even an audio-only stream?</div>

<div>We'd just do on-site encoding to x264 since the laptop is
able to do that at approx 4x real-time. That's a 190kbps
stream for full quality everything. Off-site we could use
Flumotion to re-encode and provide other options if necessary.</div>

<div>I'm a bit slammed the rest of this week so I will plan to
do some VP8 testing next week and take a peek at flumotion.</div>
