What are Time Base Correctors & WHEN do you need them? (for glitch art)

Time Base Correctors (TBC) are devices that make sure you don't get signal dropout on your non-CRT monitors whenever you're doing hard analog video signal glitches (for glitch art purposes). In my demo I take a basic dirty mix of two video signals and send the output directly to a CRT TV and a DLP projector to understand how the former handles glitches fine, while the latter drops the signal (shows blue screen of death, searching for new source, etc). Then, one at a time, I put a Sima SFX-9, Panasonic WJ-AVE 7, Roland/Edirol V-8, and a Prime Image TBC/Freeze II in between the dirty mix and the projector to get an idea of how each device stabilizes the video glitch so there's (ideally) no more signal dropout.


The DLP projector in this demo is simply acting as our example of any display that is NOT an old tube TV monitor, meaning similar signal dropout can occur in other types of displays and capture devices (with varying degrees of severity). BUT, if you're lucky, some older LCD displays actually do a decent job of not dropping the signal and can handle glitches better by themselves, than if you were to run the signal through a Roland/Edirol or Panasonic mixer first.



By the way, in this video I'm not getting super technical or nit-picky about models, manufacturing dates, and terms (there's a more in-depth resource here: http://www.digitalfaq.com/forum/video.... I'm just trying to put this info in purely practical and time-saving terms from a glitch artist's perspective. There's of course a lot more you can research about this topic if it interests you, but it's not for this video's intended audience.
