Interlaced signals from camera #
Some cameras and devices only output interlaced signals, these will be one of the following formats: 60i, 59.94i, 50i and 48i. This will generally be your shooting base rate (shooting fps) x2.
Although it is possible to stream an interlaced signal it is much better to deinterlace the footage to create progressive single frames ready to stream.
Our app can do this, there are just some changes to the settings of the source that need to be made
| Base Rate FPS | Interlaced FPS | Stream FPS |
|---|---|---|
|
24p |
48i |
24p |
|
25p |
