Note: When working with HDV sources, you may find there is up to two seconds of
delay from the video first being captured by the camera, to it showing up in Wirecast.
This is a hardware limitation of the HDV connection and cannot be corrected by
Wirecast. Many HDV cameras also have a lower resolution DV mode that, when used,
will not have the HDV delay.
DV Cameras
Generally, you should not attach more than one camera to a FireWire or USB bus, even
when using high-speed busses. The main reason for this is that most cameras will
conflict with other devices on the same bus. For example, on FireWire bus each camera
is expected to negotiate the channel it will use to transmit. Some cameras do not
negotiate at all or ignore the results of the negotiation and a conflict will result. This
causes problems in Wirecast because the incoming signal is from two cameras.
Also, since some cameras randomly pick a transmission channel, there is always a
chance that two will choose the same channel.
Sleep Mode
When a computer puts a monitor in sleep mode (screen saver mode) it also turns off the
video card. Since Wirecast uses your video card for streaming, your stream is
interrupted when the computer enters sleep mode. Wirecast automatically tells the
operating system not to put your monitor in sleep mode, but if you force your monitor
into sleep mode, your stream will stop.
Note: Wirecast will not prevent your computer from entering sleep mode. Therefore,
to ensure uninterrupted streaming, you should disable sleep mode on your computer
while using Wirecast.
S-Video & 2nd Display
You can select an external display for the output of Wirecast. For example, if you have a
projector connected to your computer using S-Video, select that projector from the
Broadcast menu to display the output of Wirecast on it. If you have a dual-head
graphics card, you can select a second monitor to display Wirecast Output.
Note: If you have two graphics cards, Wirecast may not be able to display to any
devices (monitors) on the second graphics card.
