Processing amplifier

Processing amplifier, commonly called ProcAmp, is used to alter, change or clean video or audio signal components or parameters in realtime.[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, as part of other larger multi-purpose devices in professional environments.

Software ProcAmps are also available as code embedded in media players like VLC, or in codecs like ffdshow. Software ProcAmps can process media either on the CPU or GPU.[2]

Video ProcAmp

Video ProcAmps can be used for processing standard definition 525/30 (NTSC) 625/25 (PAL) or high definition video signals.[3] ProcAmps can process video signals ranging from analog composite to SDI video signals.

Common ProcAmp Controls:

Common ProcAmp features:

  • Regenerate sync and color burst
  • Adjust sync amplitude
  • Boost low light level video
  • Reduce video wash out
  • Chroma clipping
gollark: And yet they don't have usable keybords for writing things, sufficiently large screens to do video editing and such without æ, OSes which are designed to allow data sharing between apps for purposes, a sufficiently non-locked-down system for basically any sort of scripting/programming outside of somewhat isolated environments, etc.
gollark: I only do it in emergencies or when heavpoot asks for OIR:EM or something because it's quite irritating.
gollark: Phones are not designed for content creation.
gollark: The solution is of course to replace my calculator's innards with some sort of high end microcontroller with a 2G modem, relabel the buttons, and install SSH on it.
gollark: Or, well, the connection is okay, mosh can compensate for latency, but æ the bad phone IO.
