Some cameras only export video in 1080i (interlaced) format on their HDMI output port. SlingStudio can work with such cameras by de-interlacing (or converting) their 1080i video to 1080p (progressive) format.
SlingStudio can connect to those cameras in two ways:
In either case, the 1080i video from the camera is de-interlaced (converted) into 1080p video, which is then used internally by the SlingStudio unit—your SlingStudio production is processed in progressive format. And all of your input recordings from these cameras, plus program video recordings, are saved in progressive format.
Some cameras can have their HDMI output ports set to output 1080i video, or else 1080p or 720p video. If your camera offers the option of outputting video in a progressive ("p") format, then it's best to use that. SlingStudio can then work with the camera’s video with no de-interlacing necessary.
