--------------------------------
Edmore,
Thanks for your info - I did see your issue, a slightly different link to the
discussion is also in the first comment of this issue!
Adam,
FWIW, I have been running some "silent pilot" captures of camera/screen
captures and a lot of them (usually 1 hour or 1.5 hours) do end up with
captures that are within one second of each other (they range from being off by
.1 - .5 seconds). The class that has the most trouble is a 2h 15m capture that
often has a user on Skype on the screen capture. So, I am wondering if the
additional movement on Skype is making this issue more pronounced; though the
odd thing is that the last capture (which may not have been "Skyped" on the
screen capture), the length was actually short on the video capture side.
In any case, I am wondering:
a) what is the default bitrate for these captures?
b) are they (or can they be set to) constant bitrates? [and would this actually
help performance?]
