Live capture brings external video sources into Hippotizer using a hardware capture card.
Live video from external sources such as cameras or computers may be brought into Hippotizer and used as a video source. A capture card is required.
Before using Live Capture
Before using live capture, it is important to ensure the card has been properly detected by Hippotizer. This information is best accessed within the Live Capture Tab in the configuration page of Zookeeper.
In the above image an SDI capture card has been detected.
| Note: If an installed capture card is not detected, this is commonly due to a driver issue. To fix it, stop the engine and Zookeeper and re-install the Datapath drivers. See the Hippotizer release notes for the currently supported driver version. |
Once detected, live capture inputs will appear as a list of buttons in layer source.
De-interlace
The De-interlace setting in the Live Capture source window triggers the Software De-Interlace. Software de-interlace should not be used as well as the hardware de-interlacing found in the Video Capture tab of the configuration page.
- Disabled The default. No changes are applied to captured signals.
- Enabled Interlaced signals are converted to progressive adding one frame of latency.
Using Live Capture
Acquiring a capture stream will take some time (several frames). For this reason, we recommend capturing onto a dedicated mix and using relays to send captured video around the system.
Delay in Live Capture
It is often desired to have as little latency in live capture as possible. Properly configured, Hippotizer will add 4-5 frames of delay.
For best practice guidelines please see the section on reducing live delay
