Processing amplifier, commonly called ProcAmp, is used to alter, change or clean video or audio signal components or parameters in real time [1].
Form factor
Broadcast professionals prefer to use hardware rack-mountable ProcAmps that helps them make video broadcast safe by correcting video inconsistencies. They may also be chip based, part of other larger multi-purpose devices in professional environments.
Software ProcAmps are also available, as code thats embedded in media players like VLC, encoders or decoders like ffdshow that process video, either on the CPU or GPU [2].
Video ProcAmp
Video ProcAmps[3] can be used for processing standard definition 525/30 (NTSC) 625/25 (Pal) or high definition video signals [4]. ProcAmps can process video signals ranging from analog composite to SDI video signals.
Common ProcAmp Controls:
- Brightness (Luminance)
- Contrast (Gain)
- Saturation (Amplitude)
- Hue (Phase)
