#Sync problems
Heres a few questions for the Video techie inclined folks out there,
1. I have some hardware that needs two video sources to be "sync-locked" in
order to allow overlayed switching. The manual says only "in cases where the
sources can be sync locked to the same time base, it becomes possible…." My
question is: How do I sync-lock two video sources? I thought I might have to
route through a TBC but I'm not sure I can run both video sources through one
TBC. And if I run through two TBC's would the sources be "sync-locked"? I AM
confused!!
2. The hardware also has an input for an external keyer for choma keying. The
manual refers to "feeding the unit signals produced by an external chroma keyer
(sometimes also called color keyer) or any other type of keying device." It
goes on to say "you may find theres keyers from such suppliers as Sony,
Intelligent Memory, etc" Does anyone know of such an animal, what it does or
where a person might pick one up?
3. Last question, I promise. (For now anyway 😉 ). There is a I2C serial
control bus input on the box. The manual says "The VTU has a RJ-type plug-in
jack that will permit the commection of other I2C compatible devices, as well
as external analog control devices, (such as sliders, etc)". What the heck is
an I2C serial control bus and what other devices are out there for it? BTW,
it is I squared C actually.
Any and all comers are welcome to comment, suggest, harrass, poke fun at or
enlighten me. The unit I am referring to is an IV-24 for the Amiga but the
questions refer to the video side of the house. Thanks in advance to any
answers or suggestions on finding the answers.
